What is the chemical equation for the combustion reaction between methanol and air?

CH4 + O2 ==> CO2 + H2O.

All hydrocarbons produce CO2 and H2O when they are combusted in air. The above equation isn't balanced. I assume you can do that? If not, ask OR take a shot at it and I can tell you if it is correct.

Whats CH4? Isn't methanol CH3OH?

Well, you are SO right and I am SO confused. Of course methanol is not CH4 (methane). The products still are the same. Trust me, that's right. :-)).
CH3OH + O2 ==> CO2 + H2O

The equation is not balanced.

2 CH3OH + 3 O2 → 2 CO2 + 4 H2O
So would that be right?

yes, that is balanced.
