10 g `CaCO_(3)` on heating leaves behind a residue weighing 5.6 g. Carbon dioxide released into the atmosphere at STP will be

A

2.24 L

B

4.48 L

C

1.12 L

D

0.56 L

Text Solution

Verified by Experts

The correct Answer is:
A
`CaCO_(3) to CaO + CO_(2)`
Thus 100g `CaCO_(3)` gives 22.4 L `CO_(2)` at STP. Hence 10 g will give 2.24 L `CO_(2)` at STP.
