methyl benzene + oxygen

is this just a combustion reactions so CO2 and H2O are produced?

Yes if heat is applied.
How would I balance the equation then. I`ve tried several times but it's not working out.
C7H8 + 9O2 ==> 7CO2 + 4H2O
Why is it C7H8? Dosen't every C in benzene, with the exception of the C attacthed to the methyl group, have 2 hydrogens attactches to it since C needs to make 4 bonds?
Benzene is C6H6 (each C in the benzene ring has a single carbon and alternating double bonds around the ring. So the phenyl group is C6H5 and you add a methyl group to that so it is C6H5CH3. It I didn't add wrong, that's C7H8.
By the way, the trivial name for that is toluene. Here is a page you can read about it.

Thanks so much :)
