`100 g CaCO_(3)` reacts with `1 litre 1 N HCl`. On completion of reaction how much weight of `CO_(2)` will be obtain

Options

A. 5.5g
B. 11g
C. 22g
D. 33g

Answer

C

Explanation

`underset(100g)(CaCO_(3)) + underset(2N)(2HCI) to CaCl_(2) + underset(44g)(CO_(2)) + H_(2)O`
100 g `CaCO_(3)` with 2N HCl gives 44 g `CO_(2)`
100 g `CaCO_(3)` with 1N HCl gives 22 g `CO_(2)`
