ces Mailings Review View observation does not violate the second law of thermodynamics. (d) Find the enthalpy change AHrxe for the following reaction: MgO(s) + 2HCl(g) MgCl (s) + H2O(l) Given these reactions and their associated AH's: Mg(s) + 2HCl(g) MgCl2(s) + H2(g) AH-456.9 kJ/mol Mg(s) + O2(g) MgO(s) AH-601.6 kJ/mol H2O(1) H2(g) + 1/2O2(g) AH = +285.8 kJ/mol [4 Page 2 of 5
