The equation CuCO3 -> CuO + CO2

1. Detailed information about the equation CuCO₃ -> CuO + CO₂ -> :

The chemical equation above illustrates the decomposition process of copper(II) carbonate (CuCO₃) when the temperature increases. The result of this process is the formation of copper(II) oxide (CuO) and carbon dioxide gas (CO₂).

2. Reaction conditions:

For the reaction to occur, copper(II) carbonate needs to be heated. This causes it to decompose into copper(II) oxide and carbon dioxide gas.

3. Reaction process:

• The first step in this reaction is the thermal decomposition of copper(II) carbonate. As the temperature increases, copper(II) carbonate decomposes into copper(II) oxide and carbon dioxide gas.
• The carbon dioxide gas produced will escape from the system, while the copper(II) oxide will remain.

4. Phenomena occurring:

As the temperature increases, the color of the solid will change from blue (the color of copper(II) carbonate) to black (the color of copper(II) oxide). Simultaneously, a gas will be released, which is carbon dioxide gas.
