Chem question 2

1. Reaction DHf0 / kJ mol-1
C(Graphite) + 2H2(g) ---> CH4(g) -75.0
C(Graphite) + O2(g) ----> CO2(g) -393.5
H2(g) + 1/2O2(g) ---->H2O(l) -285.9

Calculate the enthalpy change DDH2980 for the reaction:
CH4(g) + 2O2(g) ----> 2H2O(l) + CO2(g)


Must use born-haber cycle to finish the question.
