CBSE Class 11-science Answered
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.
