Sulfur dioxide in the effluent gases from coal-burning electric power plants is one of the principal causes of acid rain. One method for reducing SO2 emissions involves partial reduction of SO2 to H2 S, followed by catalytic conversion of the H2 S and the remainingSO2 to elemental sulfur:2 H2 +SO2 => 3 S + 2H2O
How many moles of a reducing agent are used in a reaction containing 1.5L of this material which possesses a density of 0.8 and a molecular weight of 56
