Write an equation for the complete combustion of C9H20

Complete combustion is the oxidation of a fuel where the only products exist as CO2 and H2O.
C9H20 + nO2 ==> nCO2 + nH2O
C9H20 + 19O2 ==> 9CO2 + 10H2O
use the molecular formula of the hydrocarbon to infer the stoichiometry of the products. The number of oxygens can then be calculated
