Answers
All the metal carbonates in Group 2 undergo thermal decomposition to give the metal oxide and carbon dioxide gas. As you go down Group 2, the carbonates have to be heated more strongly before they will decompose. So calcium carbonate is more stable than magnesium carbonate and would need to be heated more strongly in a test tube than magnesium carbonate before it decomposes .
