[00:00:00]Good morning, students.

[00:00:08]Chemical reactions and equations. So, we have to get the chemical reactions and equations.

[00:00:24]And this is our So, students So, what will be chemical reactions?

[00:00:31]Chemical reactions Initially What do you call them?

[00:00:38]Reactant. Or chemical reactions So, What do you call them? We call them product.

[00:00:45]So, what do you call them? We call them reactant.

[00:00:48]Or Always Left hand side reactant Or right hand Product Example Through Some doubt I will tell >> [clears throat] >> Uh reactant Reactant is a product.

[00:01:06]Initially Chemical reaction Any chemical reaction Initially So, what Reactant. Or Chemical reaction Chemical Reactant Reaction Final After chemical reaction What do you call them? Product and chemical Chemical reaction chemical What example?

[00:01:31]Carbon and oxygen Carbon and oxygen Reactant Carbon dioxide Product Carbon And Oxygen Chemical Reaction Reactant Carbon And oxygen Our product Carbon dioxide In the same way Calcium oxide And water and water calcium oxide and students calcium hydroxide calcium oxide and H2O calcium hydroxide uh reaction product information question chemical reaction and equation question exam three marks three marks most question What is combination reaction? Give an example. What is combination reaction?

[00:02:53]Give an example. Give an example.

[00:02:56]Give a combination reaction.

[00:02:58]combination reaction combine combine combination reaction reaction reaction reaction are known as combination reaction reaction reaction reaction two or more than get together or combine two or more than two combine and form a single product such type of are called or as combination reaction two or more than reactants are combined and form a single product such type are known combination reaction Give an example.

[00:03:56]Easy example.

[00:03:59]Example of carbon plus oxygen and carbon. Oxygen.

[00:04:04]Carbon dioxide.

[00:04:07]Calcium oxide plus H2O and water.

[00:04:11]Calcium oxide plus H2O.

[00:04:14]Calcium hydroxide.

[00:04:18]What is the combination reaction? Give an example.

[00:04:21]When two or more than two reactants When two or more than two reactants combine and form a single product and form a single product.

[00:04:34]Such type of reactions are known as the combination reaction. Example, carbon plus oxygen it gives carbon dioxide.

[00:04:47]Carbon and oxygen.

[00:04:49]Product.

[00:04:51]Carbon dioxide. This example. Reactant.

[00:04:55]Calcium oxide and H2O. Product. Calcium hydroxide.

[00:05:00]What is the combination reaction?
