PLEASE I REALLY NEED HELP Using the following equations, calculate the H 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) H2S (g) H = -19.9kJ
SO2 (g) → S(s) + O2 (g) H = +297.01 kJ
H2 (g) + 2 O2 (g) → H2O (g) Η = -286.3 kJ ​
