9. Calculate the standard enthalpy change of combustion of ethanol from the following standard enthalpies of formation: C₂H5OH (1) C(graphite) + O2(g) → CO2(g) H2(g) + 1/2O2(g) → H₂0 (1) 2 C(graphite) + 3 H2(g) + 1/2O2(g) → C₂H5OH(1) +302(g) → 2 CO2(g) + 3 H₂O(1) AH (CO₂) = -393.5 kJ/mol AH (H₂O) = -285.8 kJ/mol AH, (ethanol) = -277.1 kJ/mol
