Fruits and vegetables commonly show bruising and fungal growth when they are decomposing. Similarly for animals and insects.
If you think to lithium carbonate the reaction is:Li2CO3------------------Li2O + CO2
Examples: calcium carbonate, potassium carbonate, sodium carbonate. These compounds are decomposed before melting.
Calcite (calcium carbonate) is decomposed by heating.
Calcium carbonate is decomposed and the products CO/CO2 form a gas shielding for the weld.
Two compounds that can be decomposed by heating them in a Bunsen burner are calcium carbonate (CaCO3), which decomposes into calcium oxide (CaO) and carbon dioxide (CO2), and copper(II) carbonate (CuCO3), which decomposes into copper(II) oxide (CuO) and carbon dioxide (CO2).
Lithium carbonate is thermally decomposed by heating.
If you think to lithium carbonate the reaction is:Li2CO3------------------Li2O + CO2
The reaction is:Na2CO3--------------Na2O + CO2
Examples: calcium carbonate, potassium carbonate, sodium carbonate. These compounds are decomposed before melting.
Calcite (calcium carbonate) is decomposed by heating.
A carbonate not decomposed by heat is sodium bicarbonate. The bonds of sodium bicarbonate is so strong that too much energy is required to break them down.

no
Carbonates are decomposed by heating in oxides and carbon dioxide; the temperatures of decomposition are: - Beryllium carbonate: decomposed at room temperature. - Magnesium carbonate: 400 0C - Calcium carbonate: 900 0C - Strontium carbonate: 1 280 0C - Barium carbonate: 1 360 0C - Radium carbonate: I have not yet found data.
Magnesium carbonate is a metal carbonate that does not decompose easily at room temperature or below.
No, it is not. Calcium is a metal but calcium carbonate is not.
Calcium is a metal
