In this question we have been asked to balance the given reaction, so we have fe2o3 plus co.
00:10
This gives us fe and co2.
00:16
So first of all, let's consider the iron atoms on both sides.
00:21
So we can see on the reactant side we have two iron atoms.
00:25
So what we're going to do is we're just going to place a 2 over here, so that we have two iron atoms on the reactant side and two iron atoms on the product side.
00:36
Now next let us consider the oxygen atoms.
00:39
Now on the reactant side we have 3 plus 1, that's 4 oxygen atoms.
00:44
And over here we have two oxygen atoms.
00:46
So what we can do is we write a 2 over here, so that we end up with 2 times 2, that's 4 oxygen atoms.
00:53
Now if we do this we have 2c, so that means we have two carbon atoms, and so we're going to have to write a 2 over here.
01:01
But if we do that we end up with 3 oxygen atoms plus 2 oxygen atoms, which is 5 oxygen atoms.
01:07
But on the product side we only have 4 oxygen atoms, so this is not working...
