Assuming standard conditions, calculate the standard enthalpy of combustion of methane (CH4), given that the standard enthalpies of formation of CH4 and H2O are -74.8 kJ/mol and -285.8 kJ/mol, respectively. The balanced chemical equation for the combustion of CH4 is:CH4(g) + 2O2(g) → CO2(g) + 2H2O(l) What is the standard enthalpy change (ΔH°) for this reaction?

A chemistry student wants to calculate the enthalpy change (∆H) upon hydrolysis of magnesium chloride (MgCl2). The student knows that the enthalpy of formation (∆Hf) of MgCl2 is -641 kJ/mol and the enthalpy of formation of water (∆Hf) is -286 kJ/mol. The balanced chemical equation for the hydrolysis of magnesium chloride is MgCl2 + 2H2O → Mg(OH)2 + 2HCl. Calculate the enthalpy change (∆H) of this reaction.
