Calculate the standard enthalpy change for the reaction between calcium oxide (CaO) and water (H2O) to form calcium hydroxide (Ca(OH)2), given that all species are in their standard state and that the balanced chemical equation is:CaO(s) + H2O(l) → Ca(OH)2(s)The standard enthalpies of formation of CaO(s), H2O(l) and Ca(OH)2(s) are -635.1 kJ/mol, -285.8 kJ/mol, and -986.2 kJ/mol respectively.
