What is the combustion of cyclohexane C6H12?

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
