Assignment:
Limestone(CaCO3) is used to remove acidic pollutants from smokestack flue gases in a sequence of decomposition-combination reactions. The limestone is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite. Assuming a 74.7% yield in the overall reaction, what mass of limestone is required to remove all the sulfur dioxide formed by the combustion of 90000 kg coal that is 0.42 mass % sulfur?
Provide complete and step by step solution for the question and show calculations and use formulas.
