Preparation of Calcium Oxide: Calcium oxide, CaO, is obtained by the thermal decomposition of calcium xocarbonate(IV). Industrially, lumps of limestone are heated strongly in a furnace called a lime kiln leading to the decomposition of the limestone at around a temperature of 900 C to yield calcium oxide and carbon(IV) oxide. This reaction is a reversible reaction and the forward …
