On heating which of the following release `CO_(2)` most easily ?

A

`K_(2)CO_(3)`

B

`Na_(2)CO_(3)`

C

`MgCO_(3)`

D

`CaCO_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Thermal stability order
`K_(2)CO_(3)gtNa_(2)CO_(3)gtCaCO_(3)gtMgCO_(3)`
Therefore `MgCO_(3)` releases `CO_(2)` most easily
`MgCO_(3)overset(Delta)toMgO+CO_(2)`.
