Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.

Copper carbonate (CuCO3) turns black when heated because it decomposes to form copper oxide (CuO), carbon dioxide (CO2), and water (H2O). This color change is a result of the chemical reaction taking place during the decomposition process, which leads to the formation of copper oxide, a black colored compound.
Here are the equations for the thermal decomposition of copper carbonate (notice that a metal oxide is formed, just as it was with calcium carbonate): Copper carbonate → copper oxide + carbon dioxide CuCO3 → CuO + CO2
When copper carbonate is heated, it changes from its green color to black copper oxide.
Carbonate by itself is an ion that does not contain copper and therefore could not produce copper if heated. However, because carbonate is a negatively charged ion, no substantial number of carbonate ions can exist stably except in association with an equal number of positively charged cations to neutralize the electrical charge of the carbonate ions. If these cations are cations of copper, then copper oxide can be produced by heating the copper carbonate salt.
When copper carbonate is heated, it decomposes into copper oxide, releasing carbon dioxide gas. The remaining ionic compound is copper oxide (CuO).
When copper carbonate is heated, a thermal decomposition reaction occurs. This reaction causes copper carbonate to break down into copper oxide and carbon dioxide gas, which is released as a byproduct.
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.
The symbol for the reaction that occurs when copper carbonate is heated is: CuCO3(s) → CuO(s) + CO2(g)
This compound is the copper(II) oxide, CuO.
Either sodium carbonate or copper carbonate
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.
They form magnesium oxide, copper oxide etc. and will form carbon dioxide as a byproduct.
