in 1986 an electrical power plant in Taylorsville, Georgia, burned 8376726 tons of coal, a national record at that time. Part A Assuminf that the coal was 80% carbon and 2.9% sulfur and that combustion was complete, calculatw the number of tons of carbon dioxide produced by the plant during the year. CO2= tons Part B Assuming that the coal was 80% carbon and 2.9% sulfur and that combustion was complete, calculate the number of tons of sulfur dioxide produced...
