Consider the following reactions:1. Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g) ΔH₁ = -454.9 kJ/mol2. MgO(s) + 2HCl(aq) → MgCl₂(aq) + H₂O(l) ΔH₂ = -131.3 kJ/mol3. H₂(g) + ½O₂(g) → H₂O(l) ΔH₃ = -285.8 kJ/molUsing Hess's Law, calculate the enthalpy change for the following reaction:MgO(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g) given that the enthalpy change for the reaction Mg(s) + ½O₂(g) → MgO(s) is ΔH = -601.6 kJ/mol.
