Calcium carbonate decomposes on heating ...

Calcium carbonate decomposes on heating to give calcium oxide and carbon dioxide. How much volume of `CO_2` will be obtained by thermal decomposition of 50g `CaCO_3` ?

11.2 L

44 L

22.4 L

Text Solution

Verified by Experts

`underset(100g)(CaCO_3) to CaO + underset ("1 mole " = 22.4L)(CO_2)`
100g of `CaCO_3` at STP gives 22.4 L of `CO_2`
50g of `CaCO_3` will produce `(22.4)/(100)xx50=11.2L " of " CO_2`
