One method proposed for removing SO2 from the flue gases of power plants involves reaction with aqueous H2S. Elemental sulfur is the product.
(a) Write a balanced chemical equation for the reaction.
(b) What volume of H2S at 27 °C and 760 torr would be required to remove the SO2 formed by burning 2.0 tons of coal containing 3.5% S by mass?
(c)What mass of elemental sulfur is produced? Assume that all reactions are 100% efficient.
