Vedclass · Answer

(A) The correct answer is $A$. $MgCO_3$ is a carbonate of an alkaline earth metal,which decomposes on heating to form the metal oxide and carbon dioxide: $MgCO_3 \xrightarrow{\Delta} MgO + CO_2$. Alkali metal carbonates like $Na_2CO_3$,$K_2CO_3$,and $Rb_2CO_3$ are thermally stable and do not decompose upon heating.
