heat it :) with a Bunsen burner
Magnesium carbonate is a metal carbonate that does not decompose easily at room temperature or below.

Sodium Carbonate
Not all carbonates decompose when heated; their behavior depends on the specific type of carbonate. For example, some carbonates, like sodium carbonate, are stable and do not decompose upon heating. However, many metal carbonates, such as calcium carbonate and magnesium carbonate, do decompose at elevated temperatures, releasing carbon dioxide gas and leaving behind metal oxides. The decomposition temperature and products can vary widely among different carbonates.
Copper(II) carbonate (green copper caebonate): desintegrates into solid black copper(II) oxide and gaseous carbon dioxide. CuCO3 --[heat]--> CuOsolid + CO2,gas
Tungsten is a metal that does not decompose when heated with a Bunsen burner due to its high melting point of 3422°C. This property makes tungsten ideal for use in the filament of incandescent light bulbs.
Sodium carbonate
Metal carbonates decompose when heated, to form an oxide. For example: Calcium + Oxygen = Calcium carbonate oxide Some carbonates decompose more easily than others, in other words, it happens at a lower tempreture.
Lithium carbonate (Li2CO3) is thermally unstable compared to other alkali metal carbonates like sodium carbonate (Na2CO3) and potassium carbonate (K2CO3). This is because of its smaller ionic size and higher charge density, which leads to stronger lithium-oxygen bonds that are more easily broken by heat, causing the compound to decompose at lower temperatures.
Sodium Carbonate
no
No, it is not. Calcium is a metal but calcium carbonate is not.
