The heat of combustion of decahydronaphthalene (C10H18) is −6286 kJ/mol . The heat of combustion of naphthalene (C10H8) is −5157 kJ/mol . (In both cases CO2(g) and H2O(l) are the products.)

You may want to reference (Pages 1041 - 1047) Section 24.3 while completing this problem.

Substance ΔH∘f (kJ/mol)
CO2(g) −393.5
H2O(l) −285.83
C2H6(g) −84.68
C2H4(g) 52.30

A. Calculate the resonance energy of naphthalene.

Express your answer using three significant figures.
