Hi all, How could I balance this equation using the redox method ? CH3OH +O2 -->

Question

Explanation / Answer

CH3OH + O2 --> CO2 +H20 1) Balance C 1st. (already done) 2) Balance H 2nd. (4 hydrogen on left, so put 2 in front of H2O). CH3OH + O2 --> CO2 +2H20 3) Balance O last. Have 4 O on right, so need 4 right on left. You have 1 in CH3OH, so you need 3 in the O2. What number times 2 gives you three. (1 1/2) CH3OH + 1 1/2 O2 --> CO2 +2H20 4) But you can have 1 1/2 as a coefficient so go back and double everything to balance. 2CH3OH + 3O2 --> 2CO2 +4H2O
