[00:00:04]Hi, hello dears. Welcome to Jainam learning.

[00:00:36]Yes, hi, hi, hi. Ashwin, hi. Good evening, sir.

[00:00:43]Do I look like a sir?

[00:00:45]Okay, yeah. It's a sir, a a teacher is a line of gender in the Okay, fine.

[00:00:51]Hi, Simi. Hi, hi, hi.

[00:01:10]My name is Tarumo.

[00:01:15]My name is Tarumo.

[00:01:17]Variety beta and all.

[00:01:20]And I already said and I could tell everyone to do it and then so No matter how you must have actually module unit exam exam module exam exam chemistry chapter exam So, basically exam exam exam proper exam because >> So, you will get your timetable. And you science and the exam are in the middle of the moon. Okay, I didn't even need to do the revision class.

[00:02:17]Number exam.

[00:02:19]proper garden pattern questions in the So, time questions I'm going to analyze You are you exam Ready?

[00:02:44]I'm a exam timetable exam science exam is on May 30th, I think.

[00:02:54]May 30th Okay.

[00:02:59]proper Don't you worry Okay. So, shall we begin?

[00:03:11]Mom looks tired. Mom It would have Oh my God.

[00:03:25]The love, the amount of love you guys have for me.

[00:03:32]Okay.

[00:03:34]Okay, yes. I I'm I'm I'm science I'm I'm I'm I'm I'm science Huh?

[00:03:45]I'm I'm I'm I'm science I'm I'm How many subjects you have? in Tell me.

[00:04:01]Hey, there you go, little butter.

[00:04:04]But I you make a leap bio chem physics. You guys all know that, right?

[00:04:15]Separate down and enjoy getting out soon though.

[00:04:20]I wish you had a big guy. Hello. I know.

[00:04:22]I know number and I do you know that number? On in love subject.

[00:04:28]So I don't need me out. Can the moon on the channel by Kendall? He said that by Donald buying in the each chapter by Donald kind of party in the lemon scenario.

[00:04:38]She not really love. I never put your little darling you learn to do them all.

[00:04:42]Hey, I'm going to get that guy though.

[00:04:44]Set that guy when you tell me not to do that guy number one in the UK. So don't worry. I'm going to get that guy though.

[00:04:50]Ashwin.

[00:04:51]Pro Max Plus Ashwin Pro Max Plus.

[00:04:56]Okay, so shall we begin?

[00:04:59]Okay, Chris number two and I am. I'm going to number two and I'm going to want to. Number chapter number two and I'm going to revise the gym. I bought a lot of milk and I am.

[00:05:08]I can ready and I'm going to get a lot of milk and I am. What do you think how to take when that? What do you find emoji I got it? Number. Full fire. And I don't know. I'm going to number. Set. I do we learn? I'm going to fire. Number.

[00:05:20]I'm going to number one and I'm going to get.

[00:05:22]Number. I'm going to get.

[00:05:24]And I am. I'm going to fire. Number. I'm going to get. Number. I'm going to Number. I'm going to Number. I'm going to Number. I'm going to get.

[00:05:32]Okay.

[00:05:34]Give me some fire emojis, guys. Okay, very good. So let's begin. Number two and I'm going to number one and I'm going to chemical reactions and equations. So we will learn about the balancing and everything in the last section. First we will discuss. The type of chemical reaction. So that I have my own way of teaching. Okay.

[00:05:51]So basically each chapter love we are going to discuss about five type of reactions.

[00:05:59]Combination reaction decomposition reaction displacement reaction, double displacement reaction and redox reaction.

[00:06:27]Okay.

[00:06:33]Go along and colon and all.

[00:06:46]Okay.

[00:06:48]Yes.

[00:06:49]A chemical reaction changes and all that.

[00:06:52]There are two type of changes are there.

[00:06:56]First one in the beginning of chemical change and all.

[00:06:59]First one in the beginning of chemical change and all.

[00:07:03]Second one in the beginning of physical change and all. Second one in the beginning of physical change and all.

[00:07:10]Chemical change and all and all the way then a physical change and all that.

[00:07:18]Chemical change and physical change and all the way different and all that. And all that.

[00:07:25]And all that and all that and all that and all that and all that and all that.

[00:07:34]After so many years you guys it's been only one month. And all that and all that and all that and all that and all that and all that.

[00:07:41]Okay. And all that and all that and all that and all that and all that and all that and all that.

[00:07:45]Uh a ball or physical change chemical change at the beginning of it. It is a permanent item or change on it.

[00:07:52]I like or a permanent item or change on it.

[00:08:00]Okay.

[00:08:01]So, Okay.

[00:08:03]I like a ball and remover remove a ball temporary additional a ball a temporary change physical change and the Okay. And that and that a ball Okay.

[00:08:24]water physical a ball permanent So, or a permanent change chemical change a temporary change physical change a ball chemical change and a new molecules are formed new substances are formed Okay.

[00:08:49]new substances formed Okay.

[00:08:55]a ball complete new product So, new product or a new substance we can a chemical change whereas new molecules melt a ball water freezer ice a ball new molecules change or a temporary change and such reactions are called physical changes Okay. chemical physical change difference chapter a ball type chemical change a chemical change Okay. a chemical change a chemical change a chemical So, five type of chemical reactions Okay.

[00:10:15]So, combination As the name suggests, combine together.

[00:10:21]reactants that may combine to two or more reactants combine together or single product I tomorrow combination reaction in which a single from two or more reactants two or more reactants that may combine two or more reactants combine together combination reaction combination or reactants reactants combine single product I tomorrow and this is known as a combination reaction. Okay. I will combination reaction example Take small amount of calcium oxide or quick lime in a beaker. Okay. I will calcium oxide in the common name on the top common calcium oxide is CaO I will calcium oxide I will quick lime I will beaker and then slowly add water to this. Touch the beaker. Do you feel any change in temperature? Actually, basically number of cats quick lime in a tube quick lime in a water You better chemical reaction that I come. Okay. You could claim water I don't I don't know what you think. Thank you so much. It is slaked lime. Okay. I don't know what you think. water I don't know what you think. Thank you so much.

[00:12:20]I don't know what you think.

[00:12:23]I don't know what I don't know what you think. Thank you so much. It is slaked lime. Okay. I don't know what you think. Thank you so much. I don't know what you think. Thank you so much. I don't know what you think. Thank you so much. I don't know what you think. Thank you I don't know I don't know what you I don't know what I don't know I don't know what I don't know what you think.

[00:12:41]I don't know what you think. Thank you so much. It is slaked I don't know what you think. Thank you so much. It is slaked I don't know what you think. I don't know what you think. I don't know what you think.

[00:12:51]I don't know I don't know what you think.

[00:12:54]I I don't know what you think. Thank you so much. It is slaked lime. Okay. I don't know what you think. I don't know what you think. Thank you so much. It is slaked lime. Okay. I don't know what you think. I don't know what you think.

[00:13:00]Thank you so much. It is slaked lime.

[00:13:01]Okay. I don't know what I don't know what you think. Thank you so much.

[00:13:04]I don't know what you think.

[00:13:06]I don't know what you think.

[00:13:08]I don't know what you think. Thank you so much. It is slaked I don't know what you I don't know what you think. Thank you so much. It is slaked lime. Okay.

[00:13:15]I don't know what you think. Thank you so much.

[00:13:17]I don't know what you think. Thank you so much. It is slaked I don't know what you think. I don't know what you think.

[00:13:21]Thank you so much. It is slaked Is this a combination reaction?

[00:13:27]I don't know what you think. Thank you so much. It is slaked lime. Okay. I don't know what you think.

[00:13:40]Yes.

[00:13:44]Why? Because two reactants So, we can call it as a chemical reaction. Okay. I know.

[00:14:02]Quicklime in the Mariana calcium oxide on a water and slaked lime is calcium hydroxide.

[00:14:24]What a chemical reaction that can move?

[00:14:27]What type of chemical reaction that can move? Okay.

[00:14:33]Okay. Heat is not considered product heat is evolved here. Heat is energy.

[00:14:40]Energy is not a product. Energy is always there. Energy Okay.

[00:14:46]chemical reaction chemical reaction only either energy will be released.

[00:14:57]Okay. Only energy chemical reaction release energy is absorbed.

[00:15:09]energy absorb to do you do you do you only energy release to do you only chemical reaction energy release reactions exothermic reactions in reactions exothermic reactions Ready or not?

[00:15:36]chemical energy any form of energy energy in the bottom form of energy electrical energy of Okay. I don't know anything heat energy of Okay. I don't know anything light energy of at all.

[00:15:56]exothermic in the bottom in the release generally So, thermal energy heat energy light energy electrical energy energy release I don't know anything equation reactions I don't know anything exothermic I don't know energy absorb I don't know energy absorb I don't know I don't know I don't I don't know anything endothermic reactions Okay.

[00:16:30]I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know I don't know endothermic I don't know I don't know anything I don't know anything I don't energy involved energy involved reactions I don't know anything I don't know energy involved I think I exothermic by because you would have heat energy in the burning release the heat calcium oxide in the burning YouTube calcium oxide you would have water might have reacted with the power heat release the heat heat reaction classify the heat combination reaction on it in the burning combination of methylene reaction on the burning reaction classify combination I think exothermic reaction on it ready Okay, ready on it.

[00:18:31]combination reaction on it in the burning are you Okay, ready are you Okay, guys calcium oxide reacts vigorously with water to produce slake and lime releasing large amount of heat water react large amount of heat release the heat in the burning in this reaction calcium oxide and water combined to form a single product called calcium hydroxide.

[00:19:25]Okay.

[00:19:36]Okay.

[00:19:38]Set on off.

[00:19:48]See.

[00:20:06]Single product.

[00:20:08]Two reactants, two or more reactants combined together to form a single product.

[00:20:21]Combination reaction. And during a reaction if energy is released, it is known as an exothermic reaction.

[00:20:32]Exothermic reaction.

[00:20:36]Reactions in which heat energy is released is known as exothermic reaction.

[00:20:44]Burning of natural gas. And the burning of natural gas.

[00:20:51]CH4 carbon dioxide.

[00:21:00]Water.

[00:21:01]Exothermic on. Exothermic and the burning of energy release you do. Natural gas burn off. a semi energy is released I don't know anything so I can get out of the respiration respiration and the weather normal breathing and the kitchen with the kitchen and the food kitchen of food carbohydrate and digest the number energy cellular respiration and the kitchen so number food number energy and about carbohydrate digest the glucose in the glucose breakdown the body with energy release the chain okay so food energy release the chain I would eat the body energy release the chain energy release the chain it is also known as an exothermic reaction after the decomposition of vegetable matter and the banana number veggies number fruits number food items with the receipt of a food items microorganism breakdown chain I'm going to break down the chain of the semi energy take a release the chain of the chain energy release the chain of the decomposition of vegetable matter and the banana exothermic reaction I'm going to have a combination reaction and the clear number combination reaction number textbook examples and the number of the number combination reaction and the number of the number of the I hope a lot of the clear number of the number of the so two or more reactions and the number of the number of the combination chain single product and the number of the number of the combination reaction and the number of the number of the combination reaction and the number of the number of the and the number of the number of the and the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the energy is released and the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the number of the Yes.

[00:23:19]decomposition decomposition reactant in Thailand A B and the body single breakdown to the simple product decomposition Okay.

[00:23:41]reactant a single reactant breakdown to give simple product reactant breakdown breakdown simple decomposition Let's see.

[00:23:57]decomposition composition energy Okay.

[00:24:04]decomposition and then again energy and then energy heat energy electrical energy light energy example ferrous sulfate decomposition ferrous sulfate crystals ferrous sulfate sulfur seven seven water molecules chapter ferrous sulfate water molecules second chapter ferrous sulfate ferrous sulfate color color again ferrous sulfate crystals color color ferrous sulfate crystal color Ah, yes, I have a cookie. Very good.

[00:25:20]Always remember ferrous sulfate in the pale green pale green color color color So, ferrous sulfate Okay. ferrous sulfate crystal pale green pale green color color color fun only. Fun fun fun. Okay. Just for fun.

[00:26:29]>> [snorts] >> Okay.

[00:26:37]ferrous sulfate ferrous sulfate ferrous sulfate Okay. colorless Okay, oven colorless on it.

[00:27:04]heat energy to do that and all.

[00:27:09]You will heat energy in a absorb the heat energy.

[00:27:13]absorb the heat energy and absorb the heat energy.

[00:27:18]absorb color ferrous sulfate water data by ferrous sulfate and ferrous sulfate in a heat it again and again and again and again and again and again.

[00:27:33]color color and all.

[00:27:38]Okay, this one.

[00:27:41]What is the color and all?

[00:27:44]Ah, reddish brown and all.

[00:27:46]I have a damn colorless eye. White color, okay, white colorless. Okay. And then I will heat it again and again and again and again and again. reddish brown color and all. I don't know what it is and all. reddish brown color and all. I don't know what it is and all.

[00:28:02]ferric oxide ferric oxide and all. I reddish brown You don't open that and all. You don't open that and all.

[00:28:15]Ferrous sulfate dioxide and ferrous trioxide and all.

[00:28:21]So, what is going to happen to that? I don't know what ferrous sulfate crystals are there too. I have FeSO4.7H2O.

[00:28:29]You all don't know what heat is and all.

[00:28:30]You don't know what and all. You don't know what ferrous sulfate and all. You don't know what it is and all. You don't know what it is and all. You don't know what Okay, you don't know what ferrous sulfate and all. You don't know what heat is and all. You don't know what heat is and all. You don't know what heat in the absolute of J 2. Heat energy in the absolute of J 2 Fe2O3 sulfur dioxide sulfur trioxide in my tomorrow.

[00:29:00]Number of a single reactant in Daya now. I like other breakdown say that energy in the absolute of J 2 breakdown say that simple product I 2 Marie simple product I 2 Marie and this is known as a decomposition reaction. But even a what a single reactant breakdown say that simple product I 2 Marie and this is known as decomposition reaction. Pale green color in Daya now ferrous sulfate reaction going up all reddish brown color I 2 Marie in the kingdom. I like a reddish brown color I 2 ferric oxide I 2 Marie in the kingdom. But we are exothermic and or endothermic and or e reaction exothermic and or endothermic and or e reaction in the burning of the exothermic and or endothermic and or Either you would have energy absolute of J 2 and J 2 and J 2 and J 2. You would have absolute of J 2 and J 2 and J 2 and J 2 and J 2 and J 2 and J 2 and J 2 and endothermic reaction This is endothermic and or You would have heat energy in the absolute of J 2 and J 2 and and endothermic reaction. I feel it number of all example no comment calcium carbonate in the heat in the other calcium carbonate in the burning of the other and the kingdom. But we are calcium carbonate in the common calcium carbonate in the common name in the other and the kingdom in the common name in the other and the kingdom in the common name calcium carbonate in the heat in again even in the calcium carbonate heat energy in the absorb and even calcium oxide calcium oxide and the boiler carbon dioxide might be more calcium oxide carbon dioxide might be more Yes, very good. Limestone. Very good.

[00:31:22]chemical formula in the limestone Very good.

[00:31:31]calcium carbonate in the common name in the burning in the limestone and it all limestone limestone limestone in the heat the heat the gain number claim and get them a day boiler carbon dioxide and get them a boiler number chemical formula in the second video calcium carbonate in the burning in the CaCO3 and the heat the heat the gain number claim sorry calcium oxide carbon dioxide and get them a boiler in the boiler in the marble Heisenberg marble in the limestone and it all and it all in the generally known as limestone the marble in the in the limestone and it all >> [snorts] >> a boiler in the decomposition reaction and it all and it all and it all in the number in the single reactant in the and it all single reactant in the and it break down to the single product and it all money single reactant break down to the single product and it all money so this is and it decomposition reaction in the heat energy Okay.

[00:32:51]Okay.

[00:33:02]Who told you I don't know Heisenberg?

[00:33:05]Miss don't know Heisenberg I'm teaching chemistry.

[00:33:14]Okay.

[00:33:18]Okay.

[00:33:40]Okay.

[00:34:00]I am I am not fake.

[00:34:02]Why are you calling me fake? Why fake?

[00:34:05]What happened?

[00:34:06]Yeah, I don't know guys. You have any doubt?

[00:34:11]Wait, Maruti. Okay, wait Maruti.

[00:34:22]Come on.

[00:34:25]I don't know really.

[00:34:27]You know the same only.

[00:34:29]Really?

[00:34:38]>> Look. Look at that.

[00:34:40]Mridula Sebastian DOB female Why are you calling me fake?

[00:34:53]Okay.

[00:35:03]Mom smart beautiful 159 cm and beautiful beautiful fluent in English Huh?

[00:35:27]Okay.

[00:35:29]Okay, sure. Okay.

[00:35:36]Okay.

[00:35:38]159 cm and all that.

[00:35:41]I don't know what to call her.

[00:35:54]calcium calcium carbonate You mean calcium carbonate and water and Okay. So, guys Yes. some of you So, let colorless So, as you can see number of lead a lead a test tube a test tube number of lead a lead heat a lead nitrate >> [snorts] >> Okay.

[00:36:45]Uh, dissolve practically it is insoluble in water at all. In spite of myself yes calcium carbonate is practically insoluble in water so just water in tire I didn't you go down and see after you look.

[00:37:05]And then you would have gotten it there.

[00:37:07]Ah, yes Leon very good. We are seeing some brown fumes and then you So number color sign a lead nitrate in a heated it up with brown fumes and then we got to what happened. I'm going to knock out number 50 lead nitrate and then I do you know. I lay number 50 culture lead nitrate in the iron. I didn't heat it up with a decomposed lead oxide nitrogen dioxide nitrogen dioxide I think what they done with my clay. Oxygen gas and my tomato. Lead oxide in the nitrogen dioxide in the oxygen gas in the money. In nitrogen dioxide in the iron. I would have brown fumes in the reason and the burning. So first number lead nitrate in the iron.

[00:37:53]Lead nitrate in the burning of PB NO3 twice. You are number heated you are in the iron. Heated you are in the burning of PBO in the burning of lead oxide nitrogen dioxide or oxygen gas in the market. So can you tell me either either decomposition or earlier.

[00:38:11]Okay, you better number single reactant in the other break down cheated it up single product either money so this is also a decomposition reaction either or decomposition reaction example I know.

[00:38:25]Okay. Clear I So if the number of candidates are number of late night rate ferrous sulfate calcium carbonate in the heat it do if it alone heat energy absorb break down simple product and they are water electrolysis So basically number be careful water Okay. number be careful water number be careful be careful number water Okay.

[00:39:03]be careful be careful be careful number current current current electrode electrode test tube electrode number connect positive in the negative water current test tube bubbles change bubbles evolve So actually number some working are you water H2O water current current current current is splitting water break down hydrogen and I oxygen positive charge hydrogen and I number negative charge cathode cathode hydrogen gas release and they negative charge oxide and I positive charge anode cathode negative charge anode positive charge So anode oxygen gas I had to release the tape at home.

[00:40:28]What are electrical energy in the absorb to do what electrical energy in the absorb to do? Electrical energy in the absorb to do it that cathode and I have a hydrogen gas in kitty.

[00:40:42]Cathode and I have a hydrogen gas in kitty. Anode and I have a oxygen gas in kitty.

[00:40:52]Hydrogen and oxygen and ratio at the end of the money. Hydrogen and oxygen and ratio even at the end of the money and the money and the money.

[00:40:59]>> [snorts] >> But I am a calorie.

[00:41:06]You would have missed in the show the end of the money. Missed in the show the end of the money and the money. You would have hydrogen and oxygen and money.

[00:41:16]Either ratio and I have to get that hydrogen is to oxygen and I have to get that very good. 2:1 ratio and I have to get that very good.

[00:41:26]Because all the water molecule in there around the hydrogen and all the oxygen and all that. I like Sorry that I am on I like all the water and all that and all the hydrogen and all the oxygen and all that. So, I didn't know my break down to you more than I have to get that hydrogen and all the oxygen and get that and all that 2:1 ratio and I have to get that. Missed in the pill so happy.

[00:41:45]Though Okay, missed in the show.

[00:41:49]Yes. I believe that all the decomposition and I have to get that and all that and all that and all that and all that. What are in the iron or no?

[00:41:55]What are in the iron or electricity pass to do? Electricity pass to do? What are in the split to do? Hydrogen gas in the oxygen gas in the iron or no money market and all that. Hydrogen and I have to get that cathode and I have a oxygen and I have to get that iron or no money market and all that.

[00:42:14]Get that. up here it's again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and And again and again and again and again and again And again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and And again and again and again and again and again and again And again and again and again And again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again And again and again and again and again and again and again and again and again and again and again and again and again and again and again and again And again and again and again and again and again and again and again and again and again And again and again and again and again and again and again and again and again and again and again and again and again and again and again and again and again And again and again and again and again and again and again and again and again and Take some silver chloride in a China dish.

[00:44:34]white color sunlight in the container And then color change. Can you Can you see the color now?

[00:44:46]Okay.

[00:44:55]After we are keeping in the sunlight, it became Meenakshi, very good. It became green color.

[00:45:06]White silver chloride turns gray in sunlight.

[00:45:12]Number of silver chloride in a way that we want to make sure.

[00:45:24]sunlight on the light and the sun precaution light on the the light in the only light in the light in the energy light energy on the upper silver chloride in a way that we want to make sure that the silver chloride light energy in the absorb shadow. And then the silver chloride decompose shadow.

[00:45:48]Silver chloride decompose shadow to make sure that the silver room are they boiling chlorine gas to my tomato the silver solid on it the silver on it are they gray color in the make sure that the color in the make sure that the color in the make sure that the color in the make sure e silver chloride silver and chlorine might matter. e silver and I would take great color in the reason and the burning the clear io up a silver chloride absorbs light energy and decomposes to silver and chlorine gas.

[00:46:21]The great color is due to the due to the a formation of silver by the decomposition of silver chloride. silver chloride the decomposition of silver right to marry the one dollar you would take great color and I would take clear io and the good girl come back up either exothermic or endothermic or no Yes, be stopped at the sherry but you never get examined and I will have a headache and I It is okay I know.

[00:46:48]Clear on or in the good girl come back.

[00:46:50]Yes.

[00:46:53]Silver is great or very good so up even at the equation miss 80 to that you would have not going to the to ADC and I would recommend that break down say that and the silver room I think all the way chlorine gas to my tomorrow. It only would have not going to the chemical reaction and the burning the you would have not going to the chemical change and I would have not going to the chemical change already.

[00:47:16]very good very good Yes. The endothermic and the white energy is up so but I need to be the one dollar silver chloride for the one dollar and the one dollar number two silver bromide and the one dollar up or you would have not going to the end of the day and I would have not going to the silver bromide silver bromide and the one dollar and the one dollar silver chloride for the one dollar and the one dollar decomposition going to be the one dollar and I would have not going to the silver bromide you would have not going to the and the one dollar and the one dollar and the one dollar and I would have not going to the one dollar silver bromide and the color and the one dollar and the color of silver bromide What happens?

[00:48:13]Okay.

[00:48:18]Light energy absorbed to get decomposed to get silver a yellow silver bromide photolysis or maybe photolytic decomposition or maybe photo decomposition and for example because light energy is absorbed here.

[00:48:42]I can give you the AGCL I will write the equation with the answer. Silver bromide AGBR on it.

[00:48:53]AGBR on it. It will decompose to get silver and the boiling bromine gas might matter.

[00:49:01]Okay. About AGBR AGCL in the middle black and white photography You are the reaction going to be done.

[00:49:14]You will be ready to do black and white photography you see how it is.

[00:49:19]Okay. Yes. Apple It will be a number of decomposition reactions I can do that. But it will be a little bit again and again I can again and again. I need to do pink heart it to do it again.

[00:49:32]I need to do pink heart it to do it again.

[00:49:34]It will be a little bit again and again I need to do it again and again. So time up 8:30 class ended so we need to wind up wind it up by 8:30. So It will be okay again and again I need to do it again. Let's move on to D displacement reactions. I need to do displacement reactions Displacement reactions in the right in the I don't know what to do to find it out.

[00:50:18]photolytic decomposition photolysis photodecomposition in the right way no issues a displacement iron a more reactive metal displaces a less reactive metal from a salt solution.

[00:50:43]So more reactive metal replaces a less reactive metal from a salt solution.

[00:50:52]So potassium, sodium calcium magnesium, aluminum zinc, iron, nickel tin, lead hydrogen copper silver gold a beta and a reactivity series in the right way a reactivity series in the third chapter So number Let me check.

[00:52:19]I don't know many.

[00:52:21]It's all.

[00:52:22]It's going to go.

[00:52:28]Go for I don't know.

[00:52:37]Because So shock to me.

[00:52:49]Go for solution I don't know. I don't shock to Go for Go for Go for Go for Go for more reactive metal iron replaces less reactive metal copper from it's salted solution from its solution. Go for Go for sulfate. Go for sulfate.

[00:53:23]reactivity I don't reactivity Go for replace Go for I don't Go for Go for Go for Go for Go for Go for Go for sulfate in the ferrous sulfate ferrous color in the iron in the iron >> [cough] [clears throat] >> very good blue copper sulfate copper ferrous sulfate ferrous very good green color copper displacement Korean total solution copper MGS magnesium sulfate case case displacement Yes or no?

[00:54:57]>> [clears throat] >> Yes or no?

[00:55:16]>> [clears throat] >> My name is combination >> [clears throat] >> Wait Maridueña.

[00:55:25]Yes, not a killer. Why? Because magnesium magnesium copper copper magnesium copper reactivity is less than magnesium. magnesium Not possible I think you know.

[00:55:52]Not possible. So always remember a more reactive metal displaces a less reactive metal from a salt solution and it is known as combination reaction.

[00:56:02]It is known as displacement reaction.

[00:56:04]Clear?

[00:56:09]We are moving on to the next topic which is which is which is which is Okay.

[00:56:23]Displacement in the example on it.

[00:56:30]Zinc is more reactive than copper. So zinc copper in a displace copper chloride might react in you again. Lead is more reactive than copper.

[00:56:48]Displacement example on it. So next in the by double displacement on it. Double displacement in the by market. Reactants by the spiral ions in the ultimate exchange here. I think you are the number double displacement reaction in the by in the by. I think you are the number in the by which is sodium sulfate which is barium chloride with the mix here in the by which is young one in the by. So basically in the by which is sodium sulfate in the by. Sodium sulfate in the by in a 2 SO4. Barium chloride in the by BaCl2. I think you are the number mix in the by in the by in the by in the by. Number sodium in the by in the by sulfate in the by barium in the by in the by.

[00:57:27]I think you are the number in the by.

[00:57:28]Barium sulfate in the by in the by in the by barium sulfate in the plus barium in the by in the by in the by in the by in the Exchange of ions between exchange of ions between Are there reactants?

[00:57:55]Really?

[00:58:04]So reactants are just ions in a exchange upper even number of double displacement reaction in the body that is an exchange of ions between reactants and this is known as double displacement reaction.

[00:58:21]Sodium sulfate colorless on barium chloride and colorless on.

[00:58:29]A white Curdy substance a form to do Curdy substance in the form to do in the way A white curdy substance in the way Water insoluble like a normal precipitate precipitate at all. A white White Precipitate in the way it is even down a precipitate in the way barium sulfate on.

[00:58:55]Barium sulfate on white precipitate A pole or a guy in the way See now guy in the way to do The number of salt water in the way salt in the way to do guy in the way to do Water in the way guy in the way to do Salt in the way water in the way to do guy in the way to do salt in the way guy in the way to do in the way to do Now guy in the way to do Salt in the way water in the way to Just tell me any given salt salt in the way water in the way guy in the way to do Salt in the way water in the way guy in the way to do guy in the way to do in the way >> But you love because it is soluble in water.

[00:59:47]Insoluble in water. Because this substance is insoluble in water.

[01:00:00]Water insoluble Precipitate Precipitate Water insoluble substances are known as precipitate. And any reaction that produces a precipitate is called a precipitation reaction.

[01:00:32]Precipitation reaction in the weekend.

[01:00:37]Sodium sulfate and barium chloride Curdy precipitate to get them. A white curdy precipitate in the by the barium sulfate and which is insoluble in water.

[01:00:48]A precipitate on the other one is a double displacement reaction on the other. At the same time it will precipitate.

[01:00:55]Precipitation reaction A lot of double displacement reactions on Precipitate to produce Precipitate Potassium lead nitrate Let nitrate and potassium iodide and mix it. What do you observe?

[01:01:20]Lead nitrate and potassium iodide Color >> In spite of myself Arushi, that's because that compound has color.

[01:01:47]It will insoluble like it will come.

[01:01:49]Insoluble like it will come in the end.

[01:01:53]But I don't know what kind of a yellow precipitate in a number of garden with two.

[01:01:59]I like what you yellow precipitate in a number of garden with two. So this is yes Musin, this is an yellow precipitate in a number of observation in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate Potassium iodide in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate >> [snorts] >> Okay, number of garden with two.

[01:02:36]I had a potato I had a potato in the garden of a yellow precipitate in the garden of a yellow I had a potato in the garden of a yellow I had a potato in the garden of a I had a potato in the garden of a I had a potato I had a potato in the garden of a I had a potato in the garden of a I had a potato I had a potato in the garden of a I had a potato in the garden of a I had a potato in the garden of a I had a I had a potato in the I had a potato I had a potato in the garden I had a potato in the garden I had a potato in the garden of a yellow precipitate in the garden I had a potato in the garden of a yellow precipitate I had a I had a potato I had a potato in the I had a potato in the garden of a yellow precipitate in the garden of a yellow precipitate in the garden of a yellow precipitate here. Which is an yellow precipitate either double displacement or not.

[01:03:26]What do you think? Either double displacement or not.

[01:03:31]I'm going to only let her inspire me and let her talk. A lot of cases precipitate colorless liquids are the one and only uh never mind and the Bilal and the kind of prior and the personal the prior mean not to give bother you you can't believe I'm 29 over there Yes, this is a double displacement reaction and then Why? Because you would have exchanged of reactants and then I do let me take let me take potassium and then go to I think we're going to put that in exchange of reactants and then I do I don't need it or double displacement reaction and a very good.

[01:04:15]Very good. So it bring clear missing a vehicle or a pink heart today.

[01:04:21]vehicle or a pink heart today. I think we're going to look at the bottom oxidation and reduction and the guys we need to wind up the class by 8:30. I have another class. Okay.

[01:04:33]Okay. What is oxidation reduction?

[01:04:38]oxygen I had to get going and I think it not going to oxidation and we get I think it hydrogen remove it and we get reduction oxygen remove it and I think reduction and oxidized at the reducing and then reduce oxidizing and then we get Okay. I don't know what to do.

[01:04:58]I don't know what to do.

[01:04:59]Uh once who dominate check it out I think it don't generalize but they don't I think they don't understand what they So I'm going to get just imagine I don't know magnesium to burn to do I don't know magnesium oxide I don't know what to do.

[01:05:14]>> Okay.

[01:05:34]gains oxygen.

[01:05:44]upper gain of oxygen on again oxidation in the weekend So, magnesium is the reducing agent here. Okay.

[01:06:11]single oxide I don't react say that ball carbon monoxide to my tomorrow single oxide in the oxygen gain on again loss on some single oxide in a gain of oxygen on all loss of oxygen on another I am going to sing I do marry so loss of oxygen on a oxygen oxygen a nasty potato oxygen a nasty potato loss of oxygen on again reduction I'm going to marry single oxide in a you better reduction some reduction some to go there I'm going to number we can oxide icing a one who dominates carbon monoxide item already so carbon in oxygen and Kitty gain of oxygen oxidation gain of oxygen oxidation so carbon carbon oxidation reducing gain of oxygen oxidation oxygen for your reduction oxidation and not at the reducing reduction and not at the oxidizing okay balanced already balanced activity no copper color change so number of copper copper copper copper oxide upper brown copper black in the oxidation reduction even oxidation reduction what do you think oxidation reduction and or Either process either yes, very good.

[01:09:22]This is oxidation and then because copper and oxygen and kitty and then e process and then by then copper in a you would have oxidation some which are very good. Copper and oxidation some child copper and in the baby waking reducing agent and or oxidizing agent and or copper in a oxidation some which are even again in the baby oxidizing agent and or we get a reducing agent and or we get oxidizing agent and or we get a reducing yes, very good. Oxidation and then the good number coming in a reducing agent in the week in the week reducing agent in the week in a precipitate a soluble hour and solvent in the temperature increase in the day and or video basically number temperature good number solubility good but insoluble and I got a decent and then you are not in the missing check it up and then you are not a next time. Okay.

[01:10:25]shady Okay, very good. I think you know the number and then you are not a copper oxide in the morning watching water in the hydrogen and then you are not in the morning if you are not in the watching copper oxide in the evening and then you are not watching hydrogen and then you are not hydrogen and then you are not watching copper water might be money but copper oxide black color in the evening a black color in the evening copper oxide copper and then you are not in the evening watching brown color in the evening money I think you are not in the watching in the change and or in the morning and then you are not in the morning watching copper oxide in the evening and then you are not watching copper oxide in the area where copper I to marry.

[01:11:04]Open into the barrier between you and a copper oxide in the oxidation and reduction and also I am going to do today copper oxide in the oxidation and reduction and also I am going to do today copper oxide in the oxidation and copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide in the area oxidation and reduction and also I am going to do today copper oxide clear pink pink look hydrogen terms and another reaction mno2 mncl2 item added okay mno2 mncl2 item added it up even oxygen money chlorine so removal of oxygen added removal of oxygen reduction added in even HCL HCL cl2 item added HCL added a money chlorine added a money to the so HCL cl2 hydrogen added a boy to the so removal of hydrogen added money hydrogen hydrogen number added oxidation hydrogen a removal hydrogen oxidation hydrogen added a jada reduction so even mno2 added sorry HCL in added oxidation mno2 in a mno2 sorry mno2 in added reduction added oxidizing agent in a money to the mno2 reducing agent is HCL hydrogen only hydrogen sorry oxygen hydrogen a removal here even random number oxidation added oxygen removal hydrogen added added number by number by the reduction H2O number by consider consider so I don't believe in definition clear I don't okay I don't mno2 number by number by manganese dioxide compound okay I don't for her very good Congratulations and all super. Pin it.

[01:14:52]This question is marked. I think I must say that by marked, what do you mean by marked?

[01:14:57]What do you mean by that? MNO2 is manganese dioxide or a compound on it.

[01:15:02]Oh.

[01:15:03]Definition by the end of the double displacement in the matter that in the end of the definition by the end of the definition must have it in the end of the end and the last topic is corrosion and rancidity. Corrosion and rancidity.

[01:15:16]I don't know what the metals are. Uh moisture, acids, oxygen, air in the air that I take in. I don't know what I do in the end of the corrosion in the matter that I do. Iron in the case of the matter that I do in the rusting of iron in the matter that I do. I don't know what the silver in the matter that I do in the black coating in the matter that I do. I don't know what the copper in the matter that I do in the green coating in the end of the rusting of iron in the matter that I do in the corrosion example in the end. I don't know what I do in the end of the end of the silver in the matter that I do in the black coating in the matter that I do in the silver sulfide in the end. I don't know what I do in the end of the copper carbonate in the end. I don't know what I do in the end of the end of the ferric oxide in the end of the end of the end of the end.

[01:15:54]Okay.

[01:15:59]Huh. I don't know what I do in the end of the end of the end of the end. I don't know what I do in the end of the end of the end of the end of the end. I don't know what I do in the end of the end of the end of the end of the end of the end of the end of the end of the end. I don't know what I do in the end of the I don't know what I do in the end of the end of the end of the end of the end of the end of the end. So money. Money waste out.

[01:16:18]I don't know what I do in the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of the end of I don't know what I do I don't know what I do in the end of the end of the end of the end of the end of I don't know what I do in the end I don't know what I do in the end of the end of the end of the end I don't know what I do in the I don't know what I do in the end of the end of the I don't know what I do in the end of the end of the end of the end of the end of I don't know what I do in the end I don't know what I do in the end of the end of the end of the end I don't know what I do in the end of the end of the more minutes.

[01:17:01]like nitrogen helium What is the reduction of the oxidation agent? and a reduction oxidizing agent double displacement What was that messy?

[01:17:28]double display definition double displacement and the one that I like reactants that are similar. There is an exchange of ions between reactants.

[01:17:41]Ions and exchange and a double displacement balanced balanced You should definitely write it in a balanced physical physical physical physical Okay.

[01:18:05]balancing balancing of conservation of mass balancing balancing balancing equal So reaction number equal magnesium magnesium left side and then oxygen and and the right side and then oxygen and then and clear So one in here We will multiply by two. Then left number of atoms right side one magnesium two oxygen left side right side two magnesium two oxygen If the atoms are still balanced I think that the balance and the side of the magnesium equal to left side one magnesium or one in here two I can see here multiply by two two going to multiply left side two going to multiply two I mean number of atoms balance here two and the magnesium two magnesium two oxygen two oxygen the number of equation balanced I this is how we we balance a chemical equation in the equation of the H2 plus O2 gives H2O If the left side two hydrogen two oxygen right side two hydrogen one oxygen or two side the number of hydrogen equal but oxygen is not equal left side two oxygen in the right side one oxygen or one in here one in here one in here two one in here multiply by two going to multiply So now we two going to multiply two two going to multiply two I mean the number of atoms we count again one in here left side two hydrogen two oxygen the right side four hydrogen two oxygen or the number hydrogen again balanced I left side right side four hydrogen left side two hydrogen or or So two in here four I can one in here two or multiply by two or two going to multiply So left side one in here again or two to multiply 10.

[01:20:52]Yes, decomposition and the beginning of endothermic and example number 2 beginning of the day.

[01:20:59]Rancidity and oxidation and rancidity and the number and and fat oil and oil and the acid and the oxidation and the oxidation and the fat oxidation and the rancidity and the oxidation and basically rancidity and the oxidation reaction and the oxidation fat oil and the rancidity oxidation and the oxidation and the prevention and the oxidation and the oxidation antioxidants, okay.
