Here in this problem, an unbalanced equation is given.
00:08
And we have to first balance it, then we have to write the coefficient of aluminum.
00:14
Now, first we will balance it.
00:16
Here, on the reactant side, one aluminum atom.
00:20
And on the product side, two aluminum atoms.
00:24
So, in order to balance, we can try to write two here.
00:29
Now we have to balance the number of oxygen atoms.
00:34
Here on the reactant side, two oxygen atoms.
00:38
And on the product side, there are three oxygen atoms.
00:42
We have to balance it.
00:43
So, let's write two here.
00:46
So two times three, six oxygen atoms on the product side.
00:51
And in order to balance on the reactant side, we must write three here...
