  • C6
    • Electrolysis
      • Flow of charge by moving ions from electrolyte to negative catode and positive anode. Positive goes to cathode and negative to anode.
      • Cathode = Metals
    • Fuel Cells
      • ADS:Efficient as direct energy transferless pollutingLast longerWeight less
      • CONS:Hydrogen production produces pollutionPosonous catalysts used to produce.
      • Cathode: 2H2 -> 4H++4e-
        • Anode: 4H++02+43- -> 2H2O
    • Redox
      • Rust - Iron + oxygen + Water -> hydrated iron (III) oxide.
      • Galvanising - Layer of zinc
      • Displacement - More reactive - Less reactive
    • Alcohols
      • C(n)H(2n+1)OH
      • Production
        • Fermentation:glucose -> ethanol + carbon dioxide.
        • Hydration:Ethene + water -> ethanol
    • Ozone layer
      • cfcl -> cf2cl + cl *
        • Cl* + 03 -> OCL * + 02
          • OCl* + 03 -> cl* + 202
    • Water Hardness
      • Temporary:Calcium carbonate + water + carbon dioxide -> calciumHydrogenCarbonate.
        • Fixed by boling (removing soluble calcium ion s)
      • Permanent:calcium sulphate + water.
        • Ion Exchange resin
          • Washing Soda
    • Fats, oils and detergents
      • Saturated/Unsaturated
      • Emulsion
      • Dry Cleaning = solvent other than water
