Question
What are the products obtained from the following chemical reaction?
- Copper and carbon dioxide
- Carbon dioxide and copper oxide
- Copper oxide and carbon monoxide
- Carbon dioxide, copper, and oxygen
Hint:
The heating of solid copper(II) carbonate is a thermal decomposition reaction.
The correct answer is: Carbon dioxide and copper oxide
The heating of solid copper(II) carbonate is a thermal decomposition reaction. The addition of heat energy causes chemical bonds to break and the reactant decomposes into two products. This reaction is accompanied by a color change.
CuCO3 
CuO + CO2
CuO + CO2
