Flue gas from a coal-burning power plant was collected and tested. A) Verify the identity of one of the pollutants in the emissions from the plant using the following data. The gas is 50% sulfur by mass and 50% oxygen my mass. Under the same conditions, He effuses at a rate of 20.0 mL/min while the pollutant effuses at a rate of 5.00 mL/min. You must show all of your work using the data provided in this problem for credit. B) This pollutant is an irritant itself and is involved in the production of acid rain. Therefore, it should not be emitted into the atmosphere. One way to clean up the emissions is to "scrub" them and remove the pollutant by reacting it with hydrated lime, which is a solution of calcium hydroxide (actually more of a slurry than a true solution, but written as "aqueous"). Sulfur reacts with oxygen gas to produce the pollutant identified in part (a). The pollutant is the only product in that reaction. The pollutant gas then reacts with calcium hydroxide and more oxygen gas to produce calcium sulfate and water. Write the equations described in the preceding paragraph and then calculate the mass of calcium hydroxide needed to remove the pollutant gas from the power plant emissions for every 15.00 kg of coal burned, assuming the coal is 3.5% sulfur by mass. c) The calcium sulfate is solid waste that must also be disposed. C) Calculate the mass of calcium sulfate produced (per 15.00 kg of coal burned).
