Calculate the volume of carbon dioxide at N.T.P evolved by strong heating of 20 g of calcium carbonate.

Answer»


Solution :The balanced chemical equation is :
`UNDERSET(underset(100G)("1 mol"))(CaCO_(3))rarrunderset(underset("22.4 L at N.T.P")("1 mol"))(CaO+CO_(2))`
100 g of `CaCO_(3)` EVOLVE carbon dioxide = 22.4 L
20 g of `CaCO_(3)` evolve carbon dioxide `= ((22.4 L))/((100g))xx(20G)=4.48L`.
