  • 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).
