Explanation:

At first we check Assertion

As we know that -

  • When we heat Calcium Carbonate (CaCO3) then it give Calcium Oxide (CaO) and Carbon dioxide gas (CO2).

It shows that Assertion is incorrect.

And

In Reason -

  • Reason is correct, because on heating Calcium carbonate, decomposition reaction take place.

Hence,

Assertion is incorrect and Reason is correct.

Decomposition reaction -

  1. The reaction in which compound break down into two or more compound is called Decomposition reaction.
  2. Decomposition reaction is opposite of Combination reaction.

There are three type of decomposition reaction -

  1. Electrolytic decomposition
  2. Thermal decomposition
  3. Photo decomposition (Light decomposition)
