Calculate the enthalpy of combustion of methane if 2.56 g of methane was burnt completely in a bomb calorimeter containing excess oxygen, causing a temperature rise of 4.58 °C in the calorimeter, which has a heat capacity of 1.26 kJ/°C. The balanced chemical equation for the combustion of methane is as follows: CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) + energy.
