Hello students, in this question we have to balance some chemical reaction.
00:04
In our first reaction, we can see that carbon dioxide is reacting with h2o to give carbonic acid.
00:14
So let's balance this reaction.
00:17
If we compare number of carbon atoms in the reactants, it is 1 and in the product it is also 1.
00:22
If we look at number of oxygen atom in the reactants, it is 3 and in products it is also 3.
00:28
And the number of hydrogen atoms in reactants is 2 and in the product it is also 2.
00:34
This reaction is already balanced.
00:36
Now let's look at the second chemical reaction.
00:40
In this reaction, we can see that lamonide that is fes2 is reacting with 15 moles of o2 and 10 moles of h2o and it is giving us feooh 4 moles.
01:02
So here was also 4 moles of fes2.
01:06
We have to predict all the other products that will be formed.
01:11
So this reaction formed two products.
01:13
One is ammonite that is feooh and second will be sulfuric acid that will be h2so4.
01:21
Now balance this chemical reaction.
01:24
You can see that number of hydrogen atoms in the reactants are 20 and in the product we have already formed 4 hydrogen atoms.
01:35
So h2so4 must contain 16 more hydrogen atoms.
01:40
Therefore number of moles of h2so4 formed will be 8.
01:45
Now you can see that number of sulfur atoms in products are 8 and in reactants these are also 8.
01:53
Number of oxygen atoms have also been balanced.
01:56
This will be the balanced chemical equation and 8 moles of sulfuric acid will be formed.
02:02
Now let's look at our third reaction.
02:05
In this reaction we have been told that the feldspar is converting into edularia.
02:18
Now we know that the feldspar get hydrated to form edularia.
02:27
So edularia is a hydrated form of feldspar.
02:30
So this must be adding up to n moles of h2o to give this reaction in which feldspar will form edularia.
02:40
This will be the balanced chemical equation.
02:42
Now let's look at fourth reaction.
02:47
In fourth reaction we have been told that magnetite that is fe3o4 is converting into hematite that is fe3o4.
03:02
Hematite is actually fe2o3...
