In this question, we have to write a balanced chemical equation for complete combustion of benzene.
00:12
Complete combustion means the reaction of benzene with enough amount of oxygen gas.
00:20
So, c6, a6 plus o2 produces co2 plus water.
00:31
Now we have to balance this equation.
00:36
The reactantside has six carbon atoms.
00:40
So let me put six before co2.
00:44
Reactant side has six hydrogen atoms.
00:49
So i'll put three before water to make six hydrogen atoms balanced.
00:55
And the reactants side has two oxygen atoms.
01:01
But the product side has 12 oxygen atom here and 3 oxygen atoms here so total 15 oxygen atoms but here two oxygen atoms already there so we have to put here 15 by 2 so this side the reactor side will have 15 oxygen atoms but we can cannot put fractional number, we have to put whole number for balancing a chemical equation.
01:39
So, we need to multiply both reactant and product side with 2.
01:46
Then we'll get 15 -o -2...
