(11 points) 3. Using the following equations, calculate the AH of the reaction in which solid sulfur and water vapor combine to form sulfur dioxide (SO2) gas and dihydrogen sulfide (H2S). Show all steps of your work. H2(g) + S (s) HZS (g) H= -19.9 kJ
SO2 (g) – S (s) + O2 (g) H = +297.01 kJ
H2 (g) + 12 O2 (g) g) H=-286.3 kJ
