Calculate the standard enthalpy change for the following reaction: [CoCl(NH3)5]2+ (aq) + 4H2O (l) → [Co(H2O)6]2+ (aq) + 2Cl- (aq) + 5NH3 (g)Given that the standard enthalpy of formation of [Co(H2O)6]2+ (aq) is -1518.5 kJ/mol, [CoCl(NH3)5]2+ (aq) is -426.9 kJ/mol, and the enthalpy of vaporization of water is 44.0 kJ/mol.

Calculate the enthalpy change and the entropy change of the reaction where 2 moles of HCl(g) reacts with 1 mole of CaO(s) to produce 1 mole of CaCl2(s) and 1 mole of H2O(l). Given the bond dissociation enthalpies (in kJ/mol) of H-H is 436, Cl-Cl is 243, H-Cl is 431, and O-H is 463. The standard entropies (in J/mol K) of HCl(g) is 186.9, CaO(s) is 38.2, CaCl2(s) is 223.0, and H2O(l) is 69.9.
