2.21 describe the formation of carbon dioxide from the thermal decomposition of metal carbonates such as copper(II) carbonate

  1. Copper (II) carbonate –> (heat) Copper oxide + carbon dioxide (CuCO3 +CuO + CO2)
  2. Copper carbonate is green, colour change to black as it oxidises. Calcium carbonate, magnesium carbonate  and sodium carbonate stays white. Zinc carbonate changes from white to yellow when heated.
  3. When metal carbonates are heated, they form a carbon dioxide + metal
