Hydrogen sulfide is an impurity in natural gas that must beremoved. One common removal method is called the Clausprocess, which relies on the reaction:8 H2S1g2 + 4 O21g2¡S81l2 + 8 H2O1g2Under optimal conditions the Claus process gives 98% yield of S8from H2S. If you started with 30.0 g of H2S and 50.0 g of O2, howmany grams of S8 would be produced, assuming 98% yield?
