Calcium carbonatedecomposes on heating to give calciumoxide (quicklime) and carbondioxide. It occurs naturally as theminerals calcite (rhombohedral; r.d.2.71) and aragonite (rhombic; r.d.2.93). Rocks containing calcium carbonatedissolve slowly in acidifiedrainwater (containing dissolved CO2)to cause ...
When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gas via the reaction: CaCO3(s) CaO(s) + CO2(g). What is the mass of calcium carbonate needed to produce 93.0 L of carbon dioxide at STP? When heated, calcium carbonate decomp...
