Sodium carbonate is easily decomposed by heating: Na2CO3----------Na2O + CO2
when carbonate is heated lyperdermus thiosulfate kindogranite maglesemium magnesium gindopickranate is formed.
CuCO3 is bluish-greenish-white. If it is heated to a high enough temperature, it will decompose into Carbon Dioxide and Copper II Oxide, which is black.

Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
Copper(II) carbonate (green copper caebonate): desintegrates into solid black copper(II) oxide and gaseous carbon dioxide. CuCO3 --[heat]--> CuOsolid + CO2,gas
Sodium carbonate is easily decomposed by heating: Na2CO3----------Na2O + CO2
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.
