Question

What happens if calcium carbonate is heated and then water is added to it ?​

Answer 1

Answer:

Hence, when CaCO3 is heated it decomposes to give calcium oxide and carbon dioxide. So, the correct answer is Option B,C . This reaction is important in the erosion of carbonate rock and ions that even lead to hard water.

Answer 2

If CaCO3 is heated it produces CaO and if we add water to CaO, it gives calcium hydroxide or slaked lime [Ca(OH)2].
