Thermal Decomposition Of Metal Carbonates Aim: To investigate a range of metal carbonates and see if they thermally decompose. Written By Tauqir Sharif Research: When a metal is thermally decomposed the bond between the metal and its carbonate (carbon and oxygen) is removed and the carbonate is released as carbon dioxide. Metal Carbonate = Metal Oxide + Carbon Dioxide Malachite is an ore of copper. It is made mostly of copper carbonate. It can be crushed into a green powder. If this powder is heated it changes colour. A new substance has been made. The new substance is a black powder. This is called copper oxide. The copper carbonate has been decomposed. Copper oxide is made by thermal decomposition of copper carbonate. Carbon dioxide is also made. The formula for this is: Copper Carbonate = Copper Oxide + Carbon Dioxide (CuCO3 = CuO + CO2) The reactivity series determines how fast this reaction occurs. The reactivity...
