When balancing combustion reactions, do the carbon and hydrogen first, then the oxygen last.

Step 1: 6 carbons on the left, so you need 6 CO2 on the right.

Step 2: 12 hydrogens on the left, so you need 6 HOH on the right.

Step 3: count the number of oxygen atoms on the right = 18

step 4: divide oxygen atoms on right by 2 to get number of oxygen molecules needed on the left.

18/2 = 9

Balanced equation is:

C6H12 + 9 O2 --> 6 CO2 + 6 HOH
