Rocks and Building Materiels

- Limestone is made mainly of calcium carbonate

- Limeston is used as a building material and to make calcium oxide and cement

- Cement mixed with sand, aggregate and water makes concrete

-Metal carbonates decompose when heated to produce the metal oxide and carbon dioxide

- Carbonates react with acids to produce a salt, water and carbon dioxide

- Carbon dioxide turns limewater cloudy

- Thermal decomposition of calcium carbonate produces calcium oxide and carbon dioxide

- Calcium oxide reacts with water to produce calcium hydroxide

- Calcium hydroxide is an alkali that can be used to neutralise acids

- Calcium hydroxide reacts with carbon to produce calcium carbonate.
