Propane (C3H8) burns according to the following balanced equation:
C3H8(g)+5O2(g)→3CO2(g)+4H2O(g)
Calculate ΔH∘rxn for this reaction using standard enthalpies of formation. (The standard enthalpy of formation of gaseous propane is -103.9 kJ/mol.)

Now you need dH<sup>o</sup><sub>f</sub> fpr H2O gas.

dHrxn = (n*dH products) - (n*dH reactants)
