Answer #1

CH3OH(l) + 2O2(g) ------------> CO2(g) + 2H2O(g)   

\DeltaH0rxn = [bond energy of reactants] - [bond energy of products]

\DeltaH0rxn = [3(414) + 360 + 2 (498)] - [2(799) + 2(2(464))]

\DeltaH0rxn = [1242 + 360 + 996] - [1598 + 1856]

  \DeltaH0rxn = [2598] - [3454]

\DeltaH0rxn = - 856 KJ/mol
