Question: Using values from Appendix C, calculate the value of H for each of the following reactions: (a) CaO(s) + 2 HCl(g) CaCl2(s) + H2O(g)

Using values from Appendix C, calculate the value of ΔH° for each of the following reactions:
(a) CaO(s) + 2 HCl(g) → CaCl2(s) + H2O(g)
(b) 4 FeO(s) + O2(g) → 2 Fe2O3(s)
(c) 2 CuO(s) + NO(g) → Cu2O(s) + NO2(g)
(d) 4 NH3(g) + O2(g) → 2 N2H4(g) + 2 H2O(l)
