- Limestone
- Thermal Decomposition
- Calcium carbonate in limestone decomposes when heated
- Calcium carbonate------.> calcium oxide and carbon dioxide
- CaCO3-->CaO+CO2
- Calcium carbonate------.> calcium oxide and carbon dioxide
- Calcium carbonate in limestone decomposes when heated
- Carbonates
- Calcium carbonate reacts with Hydrochloric acid to form C02, a salt (calcium chloride) and H2O
- Adding Hydrochloric Acids makes Chloride salts
- Adding Nitric Acid makes nitrate salts
- Adding Sulphuric Acids makes Sulphate salts
- Cycle
- 1. Limestone (calcium carbonate) add heat
- 2. Makes Quicklime (calcium oxide) with CO2 given off
- 3. Add water to make Slacked lime (calcium hydroxide)

- Acid Rain
- Acid reacts with calcium carbonate to produce a salt, CO2 and H2O. Salt is soluble so dissolves in the acid rain
- Uses
- mixed with clay and heated forms cement
- cement mixed with sand to make mortar
- cement mixed with sand and aggregate makes concrete
- Thermal Decomposition
