Ethanol, C2H5OH, is being promoted as a clean fuel and is used as an additive in many gasoline
mixtures. Calculate the ΔH°rxn for the combustion of ethanol. ΔH°f [C2H5OH(l)] = -277.7 kJ/mol;

ΔH°f [CO2(g)] = -393.5 kJ/mol; ΔH°f [H2O(g)] = -241.8 kJ/mol

1. C2H5OH + 3O2 ==> 2CO2 + 3H2O
dHfrxn = (n*dHf products) - (n*dHf reactants)
Solve for dHf rxn.
