I need help with the following question: A bacterium obtains energy for growth by the oxidation of ethanol?

first to ethanal and then to ethanoic acid. Using the data calculate the change in H for the second oxidation. We were given the heat of combustion for ethanol, ethanal and ethanoic acid as -1371 kJ/mo, -1168 kJ/mol, and -876 kJ/mol respectively. Please help and I would appreciate if you outline the steps as I am extremely lost...!

A Hess Cycle approach would show you that the enthalpy change for the second oxidation is -1168 -(-876).

CH3CHO + [O] ----> CH3COOH
