FREE Expert Solution

For this problem, the reaction is the combustion of C3H8:

C3H8 + O2 → CO2 + H2O


This equation is not yet balanced. 


Balance C: We have 3 C on the reactant side and 1 C on the product side – add a coefficient of 3 to CO2:

C3H8 + O2 → 3 CO2 + H2O


Balance H: We have 8 H on the reactant side and 2 H on the product side – add a coefficient of 4 to H2O:

C3H8 + O2 → 3 CO24 H2O


Balance O: We have 2 O on the reactant side and 3(2) + 4 = 10 O on the product side – add a coefficient of 5 to O2:

C3H8 + O2 → 3 CO24 H2O

Now that we have a balanced equation, we can proceed with the problem.
