  • Chemistry - Preparation of Carbon Dioxide …

    Copper (II) carbonate is green powder that will easily decompose to form carbon dioxide and copper (II) oxide when you heat it. CuCO3 (s) -> CuO(s) + CO2 (g) copper (II) carbonate -> copper oxide + carbon dioxide To do the experiment, heat copper (II) carbonate then collect the gas that's given off using the downward delivery method.
