10. The combustion of methanol is described by the following equation: CH3OH + O2 → CO2 + 2H2O Use Hess's Law to calculate the enthalpy of combustion (AHC) of methanol given the following standard enthalpies of formation (AHP). OHP methanol =- 2380Kl/mol AHO H2O =-285.5 k I/mol AHP CO2 = - 393.51 kl/mol AHO O2 = 0k/mol
