Limestone containing 82% of calcium carbonate, 13% of magnesium carbonate and 5% of silica (insoluble) is calcined by heating to 1273 K to drive off carbon dioxide gas and form calcium oxide and magnesium oxide. Calcination of calcium carbonate is 95% complete and that of magnesium carbonate is 90% complete. (a) What is the analysis of lime obtained by calcinations (b) What weight of carbon dioxide obtained by the calcination of 1000 kg of limestone? MW : Mg=24.32 g/mole

Question

Limestone containing 82% of calcium carbonate, 13% of magnesium carbonate and 5% of silica
(insoluble) is calcined by heating to 1273 K to drive off carbon dioxide gas and form calcium oxide and
magnesium oxide. Calcination of calcium carbonate is 95% complete and that of magnesium
carbonate is 90% complete. (a) What is the analysis of lime obtained by calcinations (b) What weight
of carbon dioxide obtained by the calcination of 1000 kg of limestone? MW : Mg=24.32 g/mole
