Vedclass · Answer

(B) The thermal stability of alkaline earth metal carbonates increases down the group,while alkali metal carbonates are generally more stable than alkaline earth metal carbonates.The order of thermal stability is: $K_2CO_3 > Na_2CO_3 > CaCO_3 > MgCO_3$.Since $MgCO_3$ has the lowest thermal stability,it decomposes most easily upon heating to release $CO_2$ gas.The reaction is: $MgCO_3 \stackrel{\Delta}{\longrightarrow} MgO + CO_2$.

On heating,which of the following releases $CO_2$ most easily?
