- Group 2 Alkaline Earth Metals
- Effects of heating carbonates
- General formula of group 2 carbonates is MCO3. when it's heated, it gives MO and CO2
- Carbonates become for difficult to decompose as you go down the group
- Example: Magnesium carbonate decomposes more easily than calcium carbonate over a Bunsen flame.
- Therefore the THERMAL STABILITY of calcium carbonate is GREATER than magnesium carbonate.
- The decomposition of calcium carbonate (limestone) is an important process, it's used to manufacture calcium oxide (quicklime).
