Answer 2

Answer:

The correct sequence of thermal stability of the following carbonates is,

option (C) $MgCO_{3} < CaCO_{3} < SrCO_{3} < BaCO_{3}$

Explanation:

Thermal stability is directly proportional with the size of the cation in carbonates.

Hence, Alkaline earth metal carbonates grow more thermally stable as we proceed down the group because they need more heating to breakdown.

Hence the increasing order of alkaline earth metal's cationic size is,

Mg<Ca<Sr<Ba

So, the most thermally stable carbonates are of Barium carbonate followed by Strontium carbonate followed by Calcium carbonate and then Magnesium carbonate.

Hence, the correct order is,      $MgCO_{3} < CaCO_{3} < SrCO_{3} < BaCO_{3}$.
