Question

Why thermal stability of carbonates
increases while of hydrides
decreases in grp 2 elements.? Pls explain in detail​

Answer 1

Explanation:

Both carbonates and nitrates of group 2 elements become more thermally stable down the group. The larger compounds further down require more heat than the lighter compounds in order to decompose. All the carbonates in this group undego thermal decomposition to the metal oxide and carbon dioxide gas.
