What is an example that shows that the combustion of methane produces 802 kJmol of energy?
When one mole of methane ($CH_4$) combusts, it releases 802 kJ of energy. The balanced chemical equation for this reaction is: $CH_4(g) + 2O_2(g) \rightarrow CO_2(g) + 2H_2O(g) + 802 kJ$.

What is molar enthalpy change?
Molar enthalpy change, also known as molar enthalpy of reaction, is the amount of heat energy released or absorbed during a chemical reaction per mole of a substance. It is usually expressed in units of kJ/mol. The molar enthalpy change can be positive (endothermic) if heat is absorbed or negative (exothermic) if heat is released during the reaction.
