Thermal decomposition, carbonates and the limestone cycle

By the end you’ll be able to

• describe thermal decomposition as the breakdown of a compound by heating and apply it to the decomposition of metal carbonates to metal oxides and carbon dioxide
• write balanced symbol equations for the thermal decomposition of carbonates and for the reactions in the limestone cycle
• describe limestone as mainly calcium carbonate and state its uses, including building material, manufacture of lime and neutralisation of acidic soils or industrial waste gases where specified
