- Limestone is useful for building because it can make calcium oxide and cement
- Limestone is mainly calcium carbonate (CaCO3)
- When heated strongly calcium carbonate decomposes to form carbon dioxide and calcium oxide- this is done in industry using kilns as they get to extremely high temperatures (THERMAL DECOMPOSITION)
- ALL metal carbonates decompose to form a metal oxide and carbon dioxide
- ALL carbonates react with acid to produce a salt, water and co2
- limestone damaged by acid rain because the calcium carbonate reacts with…
