- Calcium Carbonate
- Limestone is mainly made up of calcium carbonate
- CaCO3
- Can be thermally decomposed to make calcium oxide and carbon dioxide
- When something thermally decomposes it breaks down into two or more substances
- Other carbonates like magnesium and calcium can thermally decompose in a similar way
- Some cant decompose in a normal lab because Bunsen burners don't get hot enough
- Calcium oxide reacts with water to make calcium hydroxide
- Can be used to neutralise acids
- Calcium hydroxide in water produces limewater
- Reacts with carbon dioxide to produce calcium carbonate
- Used to test for carbon dioxide
- Carbon dioxide turns it water
- Carbonates react with acids to produce carbon dioxide, salt, and water
- Limestone is damaged by acid rain
- Can be heated with clay to make cement
- Cement mixed with sand makes mortar
- Cement and sand and aggregate makes concrete
