Question

burning of lime to give calcium oxide is which process

Answer 1

Explanation:

Burning of the lime to give calcium oxide is by heating process. By heating the lime to certain temperature , the molecule of lime breaks in many compounds and gives calcium oxide . This types of reaction is also called as Exothermic reaction.

Answer 2

Answer:

The process of burning of lime to give calcium oxide is by Calcination.

Explanation:

•Limestone is used to make calcium carbonate, calcium oxide and calcium hydroxide. All these have important applications in home and industry, so it is important to know how they are made.

•Calcium carbonate is occurs naturally in limestone. When limestone is heated strongly, the calcium carbonate present in it absorbs heat (endothermic) and decomposes to form calcium oxide. When limestone is heated, it gives off an orange glow. This process is called Calcination

• The word equation for the reaction is:

calcium carbonate → calcium oxide + carbon dioxide

The Chemical reaction for the reaction is:

CaCO3(s) → CaO(s) + CO2(g)

Calcium oxide (also known as quicklime) is a key ingredient in the making of cement and is also used to make certain types of plaster.
