Arrange carbonates fo group `2` in increasing order of thermal stability.

Explanation

To arrange the carbonates of Group 2 in increasing order of thermal stability, we need to consider the factors that affect the stability of these carbonates. The carbonates in question are:

1. Beryllium carbonate (BeCO₃)
2. Magnesium carbonate (MgCO₃)
3. Calcium carbonate (CaCO₃)
4. Strontium carbonate (SrCO₃)
5. Barium carbonate (BaCO₃)
