Sulfur dioxide so2 can be reduced by hydrogen disulfide h2s

Question

Sulfur dioxide (SO₂) can be reduced by hydrogen disulfide (H₂S), producing sulfur in its elemental form and water (H₂O). Using Hess's law and the reactions below, determine the overall enthalpy for the reaction between SO₂ and H₂S.  Make to clearly show your work.

H₂ (g) + S (s) → H₂S (g)                         ΔH = -20.6 kJ

SO₂ (g) → S (s) + O₂ (g)                         ΔH = +296.8 kJ

2H₂ (g) + O₂ (g) → 2H₂O (g)                   ΔH = -285.8 kJ
