What is the correct order of increasing thermal stabilities of-

1.Pottasium Carbonate

2.Magnesium Carbonate

3.Calcium Carbonate

4.Beryllium Carbnate

Expert Answer:

The temperature at which group 2 carbonates start to decompose increases down the group.

Potasium Carbonate is very difficult to decompose.

Beryllium carbonate is so unstable that it does not exist at room temperature.
