The reactions given are already balanced so we proceed to gather the standard enthalpy of formation values from the table. ###### 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 =
