Combustion reactions always contain products of CO + H2O with the addition of O2 (oxygen) in the reactant.
In this case it would be:
C3H7OH OR C3H8O (if you count up all the H’s)
We’re just going to use C3H7OH since that’s what you were given so it’ll be easier for you that way.
C3H7OH + O2 -> CO2 + H2O
Balanced:
2 C3H7OH + 9 O2 -> 6 CO2 + 8 H2O
