8. Considering the structural changes on going from methane to ethane along with the AH, for the combustion of the reactions, what can you infer about the role of the number of carbon atoms to the amount of energy released from combustion? 9. Calculate and compare the specific enthalpy (magnitude of enthalpy of combustion divided by gram of substance, kJ/g) obtained from combustion of 1.0 g of the carbohydrate sucrose (C12H22011) with the specific enthalpy obtained from the combustion of 1.0 g of the lipid oleic acid (fatty acid derived from olive oil, Ci8H340z). Postulate why the carbohydrate or lipid has a larger specific enthalpy C12H22011+12 02 12 CO2 + 11 H2O C18H3402 + 25.5 02 18 CO2 + 17 H2O
