- 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
- Cl* + 03 -> OCL * + 02
- cfcl -> cf2cl + cl *
- 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
- Ion Exchange resin
- Temporary:Calcium carbonate + water + carbon dioxide -> calciumHydrogenCarbonate.
- Fats, oils and detergents
- Saturated/Unsaturated
- Emulsion
- Dry Cleaning = solvent other than water
- Electrolysis
