A chemistry student needs to calculate the standard enthalpy change for the combustion reaction of methane (CH4) to produce carbon dioxide (CO2) and water (H2O) at 298 K. The student is given the following information: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) ΔH°rxn = -890.4 kJ/molThe enthalpy of formation of CH4(g) and H2O(l) are -74.8 kJ/mol and -285.8 kJ/mol, respectively. Using this data, what is the standard enthalpy change for the combustion reaction of methane (CH4) to produce carbon dioxide (CO2) and water (H2O) at 298 K?
