Well it makes carbon dioxide and water.
CO2
and
H2O
Meaning there are three lots of oxygen in there..:S

Or...
It might make CO2 + 2H2O, using 2O2... (hint: start from methane, CH4, and work from there)

that's not how it works
CH4 + 2 O2 = CO2 + 2 H2O
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
for example

Edit: sorry, edited. I initially used fucking ">"

Or just this:
Less confusing.

I still find it somewhat confusing

but meh
