Solution

The correct option is D $100$ g
The reaction is $C a C O_{3} ⇌ C a O + C O_{2}$ .

One mole of calcium carbonate on decomposition gives one mole of calcium oxide.

The molecular weight of calcium carbonate and calcium oxide are $100$ g/mol and $56$ g/mol respectively.

Thus, the decomposition of $100$ g of calcium carbonate will give $56$ g of calcium oxide.
