Vedclass · Answer

(B) The general thermal decomposition reaction for alkaline earth metal carbonates $(MCO_3)$ is:$MCO_3(s) \xrightarrow{\Delta} MO(s) + CO_2(g)$Where $M$ represents an alkaline earth metal $(Be, Mg, Ca, Sr, Ba)$.From the reaction,it is clear that the products are a metal oxide $(II)$ and carbon dioxide $(I)$.Therefore,the correct option is $B$.

The carbonates of alkaline earth metals decompose on heating to give:
$I$. $CO_2$
$II$. Metal oxide
$III$. $H_2 O$
$IV$. $CO$
