Question

what happens when copper carbonate is heated? mention the type of reaction

Answer 1

hey mate here is ur ans

this is thermal decomposition
the light green copper carbonate when heated it gives copper oxide ( a black residue) and carbon dioxide is evolved

hope it helps

Answer 2

Investigating what happens when a compound copper carbonate is heated. When green copper carbonate{CuCO3} is heated it decomposes forming copper oxide {CuO} and carbon dioxide {CO2}.

CuCO3(s) + heat → CuO(s) + CO2(g)

(green)                            (black)
