Answer

The enthalpy change (ΔH) for the complete combustion of methanol is a measure of the energy released during the reaction. This reaction is exothermic, meaning it releases heat. To determine the correct answer, one can refer to standard enthalpies of formation for the reactants and products involved in the combustion of methanol.

Generally, the heat released in the combustion of methanol is typically around -1452 kJ mol⁻¹. Hence, the correct answer is:

C. -1452 kJ mol⁻¹.
