Form 3 Science Chapter 6 Minerals in earth crust

  1. 1. • Natural• Solid• Inorganic• Definite chemical composition• Atoms are organized in specific way
  2. 2. Inactive Elements form Exist freely Do not combine with otherMinerals exists in elements Active Compounds form Combination of metals and non- metals
  3. 3. Minerals are solid elements or compounds found naturally in the earth crust Natural Natural elements compoundsGold Silver Carbon Oxides Carbonates Silicates Sulphides Iron Calcium Aluminium Iron oxide carbonates silicates suphides
  4. 4. Cassiterite – Tin Oxide Haematite – Iron OxideBauxite – Aluminium Oxide
  5. 5. Galena – Lead Sulphide
  6. 6. All Oxides, Sulphides and Carbonates – Insoluble in water(except Potassium and Sodium)
  7. 7. • Metal carbonates are unstable and break down into metal oxides and carbon dioxide
  8. 8. • Very Stable• Do not break down when heated• Only change in colour• Only silver oxide breaks down when heated Silver oxide → Silver + Oxygen
  9. 9. • Break down when heated• Metal sulphides break down into metal oxide and sulphur dioxide gas when heated.Zinc sulphide → Zinc oxide + Sulphur dioxide
  10. 10. True or False• Magnesium is more reactive metal than calcium• Copper is more reactive than iron• Zinc carbonate becomes zinc oxide and carbon dioxide gas is produced when heated• Heating Magnesium sulphide produces sulphur dioxide gas• Burning silver oxide produces silver and oxygen
