Copper carbonate decomposes upon heating to yield copper oxide, carbon dioxide, and oxygen gas. The reaction can be represented by the following equation: CuCO3(s) -> CuO(s) + CO2(g) + O2(g).
CaCO3 on thermal decomposition gives CaO (calcium oxide) and CO2(carbon dioxide)

Why would the thermal decomposition of calcium carbonate require a higher temperature than that required for copper carbonate?
The thermal decomposition of calcium carbonate requires a higher temperature than copper carbonate because calcium carbonate is more stable and has a stronger chemical bond between calcium and carbonate ions. This higher temperature is needed to break these bonds and initiate the decomposition process. Additionally, calcium carbonate has a larger ionic size compared to copper carbonate which also contributes to the higher temperature needed for decomposition.
Which gas is produced when a carbonate undergoes thermal decomposition?
Carbon dioxide is the gas produced when a carbonate undergoes thermal decomposition. This process breaks down the carbonate compound into oxides and carbon dioxide gas.
Why does green copper carbonate go black?
Green copper carbonate turns black when heated because the heat causes it to decompose into copper oxide, which is black in color, and carbon dioxide gas is released. This chemical reaction changes the composition of the compound, resulting in the color change.
Is heating copper carbonate a chemical change?
Yes, heating copper carbonate is a chemical change because it undergoes thermal decomposition to form new substances, copper oxide and carbon dioxide. This is a chemical reaction that results in the formation of different compounds with distinct properties.
What type of reaction occurs when calcium carbonate is heated?
When calcium carbonate is heated, it undergoes a chemical reaction called thermal decomposition. This results in the formation of calcium oxide (quicklime) and carbon dioxide gas being released as a byproduct.
What is the balanced symbol equation for the thermal decomposition of copper carbonate?
The balanced symbol equation for the thermal decomposition of copper carbonate is: CuCO3(s) -> CuO(s) + CO2(g)
What type of reaction occurs when copper carbonate is heated?
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.

Additionally, calcium carbonate has a larger ionic size compared to copper carbonate which also contributes to the higher temperature needed for decomposition.
Does copper carbonate decompose when heated?
Yes, copper carbonate decomposes when heated, forming copper oxide and carbon dioxide gas as products. The reaction is often used in chemistry labs to demonstrate thermal decomposition.
What is the chemical equation of thermal decomposition of ammonium carbonate?
The chemical equation for the thermal decomposition of ammonium carbonate is: (NH4)2CO3 → 2NH3 + CO2 + H2O
What are the products of thermal decomposition reaction of lead carbonate?
The thermal decomposition of lead carbonate (PbCO3) produces lead oxide (PbO) and carbon dioxide (CO2) as the products.
What is the equation for the thermal decomposition reaction of zinc carbonate?
The thermal decomposition reaction of zinc carbonate can be represented by the equation: ZnCO3(s) → ZnO(s) + CO2(g)
What is the word equation for thermal decomposition of sodium carbonate?
The word equation for the thermal decomposition of sodium carbonate is: sodium carbonate → sodium oxide + carbon dioxide.
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 name when calcium carbonate decompose?
i think its thermal decomposition
Which gas is produced when a carbonate undergoes thermal decomposition?
Carbon dioxide is the gas produced when a carbonate undergoes thermal decomposition. This process breaks down the carbonate compound into oxides and carbon dioxide gas.
What temperature does thermal decomposition occur at for magnesium carbonate?
Thermal decomposition of magnesium carbonate occurs at around 350-400°C. At this temperature, magnesium carbonate breaks down into magnesium oxide and carbon dioxide.
