Question

CH3OH + O2 & WHAT'S THE RESULT?

Answer 1

Take a count of what you have first

CH3OH + O2 --> CO2 + H2O

H = 4 H = 2
O = 3 O = 3
C = 1 C = 1

Match H first, then O, then N then C. Since there is no N, the order of balancing is H -> O -> C

CH3OH + O2 --> CO2 + 2H2O

which increases O to 4 on right and 3 O on left

2CH3OH + O2 --> CO2 +2H2O

add 1 more CH3OH to try to get the Os to equal; but that increases number of Hs so increase the H2O on the left to 4 so that the Hs match up. It also increases Cs so Os jump again and so do Hs

2CH3OH + 3O2 -> 2CO2 + 2H2O

with a need for more Hs you can add more Hs by increasing H2O to 4. O2 on left can now be balanced to make up difference of O

2CH3OH +3O2 --> 2CO2 +4H2O
