What is the balanced chemical equation for: Liquid methanol (CH3OH) combusted in oxygen gas to yield carbon dioxide gas and liquid water?

The balanced chemical equation for the combustion of liquid methanol in oxygen gas to yield carbon dioxide gas and liquid water is:

##"2""CH"_3"O""H""(l)"## + ##"3""O"_2"(g)"## ##rarr## ##"2""CO"_2"(g)"## + ##"4""H"_2"O""(l)"##

If you multiply the coefficients (the numbers in front) times the subscripts for each element in each formula, you will find that there are 2 atoms of carbon, 8 atoms of hydrogen, and 8 atoms of oxygen on both sides of the equation, so it is balanced.
