Answer:
Black copper oxide and black carbon powder are mixed together and heated up. The gas evolved is passed into a solution of calcium hydroxide (lime water), a white precipitate of calcium carbonate is formed as the gas passes through the lime water. This shows that carbon dioxide is being produced.

If a copper carbonate is heated with carbon, a chemical reaction takes place. ... Then the carbon reacts with the copper oxide liberating pure metal in a type of displacement reaction. The metal carbonate is reduced (loses oxygen) as the carbon is oxidised (gains oxygen).
