Endothermic because thermal decomposition is the breakdown of a compound using heat. Remember endo means more energy is taken in breaking the bonds of copper carbonate than there is given out when making the bonds of copper oxide and carbon dioxide.

Why does green copper carbonate go black?
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.
Why would the thermal decomposition of calcium carbonate require a higher temperature than that required for copper carbonate?
As it requires more energy to break the bonds of calcium carbonate,as it is more reactive meaning it combines with elements in the air and atmosphere, and copper is a less reactive metal.
What type of reaction occurs when calcium carbonate is heated?
Thermal decomposition.
Which gas is produced when a carbonate undergoes thermal decomposition?
Carbon Dioxide
What is the equation for heating calcium carbonate?
Calcium carbonate --> Calcium oxide + Carbon dioxide Its an example of thermal decomposition.

Write a symbol equation for the reaction when copper carbonate is heated?
The thermal decomposition in this case is: CuCO3 -------------CuO + CO2
Symbol equation when copper carbonate is heated?
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
What is the chemical equation of thermal decomposition of ammonium carbonate?
Decomposition of ammonium carbonate:(NH4)2CO3 --> 2 NH3 + CO2 + H2O
What is the name when calcium carbonate decompose?
i think its thermal decomposition
Why would the thermal decomposition of calcium carbonate require a higher temperature than that required for copper carbonate?
As it requires more energy to break the bonds of calcium carbonate,as it is more reactive meaning it combines with elements in the air and atmosphere, and copper is a less reactive metal.
From the thermal decomposition of copper carbonate how can you use conservation of mass to measure the amount of carbon dioxide produced?
Before thermal decomposition, weigh the mass. Thermally decompose. Allow to cool Re-weigh. The difference in the masses is the mass of CO2 released.
What type of reaction occurs when calcium carbonate is heated?
Thermal decomposition.
Which gas is produced when a carbonate undergoes thermal decomposition?
Carbon Dioxide
What temperature does thermal decomposition occur at for magnesium carbonate?
Seng huat
What type of reaction occurs when copper carbonate is heated?
DECOMPOSITION
What happened carbonate heated?
A thermal decomposition reaction occur:CaCO3 = CaO + CO2
