When 0.2490 moles of methane, CH4(g) is burned in excess oxygen at thermodynamic standard state, 221.74 kJ of heat is released. What is ΔHfor the combustion for 1 mole of methane, CH4(g)? CH4(g) + 2 O2(g) -> CO2(g) + 2 H2O(l) ΔHrxn= ______________________ 2) What is the enthalpy change for making exactly 2 moles of methane (instead of combusting the methane) by the following reaction: CO2(g) + 2 H2O(l) -> CH4(g) + 2 O2(g)
