Which one of the following reactions is an example for calcination process?

Options

  1. A2 A g + 2 H C l + ( O ) → 2 A g C l + H 2 O
  2. B2 Z n + O 2 → 2 Z n O
  3. C2 Z n S + 3 O 2 → 2 Z n O + 2 S O 2
  4. DM g C O 3 → M g O + C O 2

Correct answer

D. M g C O 3 → M g O + C O 2

Step-by-step solution

The process of heating the concentrated ore in the absence of air is known as calcination. The carbonate ore gets decomposed to form oxide of metal on calcination.
