(choose chapter or problem)

The gasification of coal is a method of producing methane by the following reaction. C(s) + 2H2(g) CH4(g) H = ? Find H by using the enthalpy changes in the following combustion reactions: C(s) + O2(g) CO2(g) H = -394 kJ H2(g) + _1 2 O2(g) H2O(l) H = -286 kJ CH4(g) + 2O2(g) CO2(g) + 2H2O(l) H = -891 kJ A. 75 kJ B. -75 kJ C. 1856 kJ D. -1856 kJ
