If a copper carbonate is heated with carbon, a chemical reaction takes place. Initially the copper carbonate thermally decomposes into copper oxide. 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). The gaseous product can be flushed through lime water, turning it cloudy, proving that it is carbon dioxide. This is a chemical reaction since new products have been formed.
