Explanation:

Aim:

By reducing copper carbonate with HCl, to illustrate the law of conservation of mass.

Procedure:

1. Place some copper carbonate powder in a test tube.

2. Pour some diluted HCl into the test tube.

3. Use a Bunsen burner to slowly heat the test tube.

4. Carefully examine the test tube and note any changes when the reaction is finished.

Observations:

1. When copper carbonate breaks down, copper oxide, water, and carbon dioxide are produced.

2. Bubbles appearing in the test tube indicate the evolution of carbon dioxide.

3. The mixture's color switches from blue to green.

Conclusion:

The dissolution of copper carbonate in hydrochloric acid serves as a demonstration of the law of conservation of mass. Both the reactants' and the products' masses stay constant.
