Question

steps of formation of compound calcium oxide​

Answer 1

Preparation of Calcium Oxide

Calcium oxide can be produced by thermal decomposition of materials like limestone or seashells that contain calcium carbonate (CaCO3; mineral calcite) in a lime kiln.

The process that is used to prepare burnt lime is known as calcination. It is a process that starts with thermally decomposing the reactants at high temperatures but ensuring that the temperature is kept well below the melting point.

Calcium carbonate undergoes calcination at temperatures ranging between 1070oC-1270oC. These reactions are usually held in a rotary kiln. The products formed as a result of the reaction are burnt lime and carbon dioxide.

CaCO3 → CaO + CO2
