Question

State the process of preparation of CaO​

Answer 1

Answer: Calcium oxide or lime is prepared by the process called calcination. This is achieved by heating the material to above 835 °C (1,517 °F), a process is known as calcination or lime-burning, to release a molecule of carbon dioxide (CO₂), leaving quicklime.

Melting Point: 2,572°C (4,661°F)

Compound Name: Calcium oxide.

State: Solid

Boiling Point: 28500 C

Answer 2

Answer:

it's written down in explanation

Explanation:

calcium Oxide (CaO) is generally known as quicklime or burnt lime , it si commonly used chemical compound . It is solid at room temperature . It is prepared by heating calcium carbonate (e.g , limestone ) in a distinct like kiln to about 500°c to 600°c , decomposed it into the oxide and carbon dioxide .
