Question

Calculate ∆H˚ for the following reaction using the given bond dissociation energies.

CH4 (g) + 2O2 (g) --> CO2 (g) + 2H2O (g)

Bond.......∆H˚ (kJ/mol)
O-O........142
H-O.........459
C-H.........411
C=O........799
O=O........498
C-O.........358

∆H˚ = ________kJ/mol

This reaction is endothermic or exothermic?

Please help! I'm so confused!
