Calculate the standard enthalpy change for the reaction between hydrochloric acid (HCl) and ammonia (NH3) to produce ammonium chloride (NH4Cl) if the reaction is carried out in a solution of water (H2O), given the following information:HCl(aq) + H2O(l) -> H3O+(aq) + Cl-(aq) ΔH1 = -74.8 kJ/mol NH3(aq) + H2O(l) ⇌ NH4+(aq) + OH-(aq) ΔH2 = -51.8 kJ/mol NH4Cl(s) → NH4+(aq) + Cl-(aq) ΔH3 = 15.2 kJ/mol Ensure that the answer is in kJ/mol.
