Coal fired power plants freqently encounter coal that is 3.90% sulfur by mass. when this coal is burned at a power plant the sulfur is converted into sulfur dioxide gas, which is a pollutant. to reduce sulfur dioxide emissions, calcium oxide is used to react with the sulfur dioxide and form solid calcium sulfite. assume coal is C26H54.
