Problem Details

Using values from Appendix C in the textbook, calculate the standard enthalpy change (kJ) for each of the following reactions. 

2SO2(g) + O2(g) → 2SO3(g)                              ΔH°rxn =


Mg(OH)2(s) → MgO(s) + H2O(l)                         ΔH°rxn =


N2O4(g) + 4H2(g) → N2(g) + 4H2O(g)                ΔH°rxn


SiCl4(l) + 2H2O(l) → SiO2(s) + 4HCl(g)              ΔH°rxn =
