$Na$

Vedclass · Answer

(A) The correct answer is $A$. Alkali metal carbonates,except for $Li_2CO_3$,are highly stable and do not decompose upon heating. $Na_2CO_3$ and $K_2CO_3$ are thermally stable. In contrast,alkaline earth metal carbonates (like $MgCO_3$) and other metal carbonates decompose upon heating to form their respective oxides and $CO_2$ gas. As we move down the group,the thermal stability of carbonates increases.

Which of the following metals forms stable carbonates that do not decompose upon heating?
