Resource summary

NATIONAL 5 CHEMISTRY UNIT 3 CHEMISTRY IN SOCIETY
1 METALS
1.1 Free electrons which is also called DELOCALISED
1.2 Alloy
1.2.1 An alloy is a mixture of a metal with at least one other element
1.2.2 Making an alloy changes the properties of the metal
1.3 Extraction of metals from ores
1.3.1 Heat
1.3.2 Heat and Carbon
1.3.3 Electrolysis
1.3.3.1 OPPOSITES ALWAYS ATTRACT
2 OIL RIG
2.1 OXIDATION IS LOSS
2.2 REDUCTION IS GAIN
3 PERCENTAGE MASS CALCULATIONS
3.1 calculate the gram formula mass
3.2 then its regular percentage calculations
4 BATTERIES / CELLS
4.1 Simple Cell
4.1.1 INSERT IMAGE HERE
4.1.2 Sugar solution cannot be used as it is a covalent so will not conduct
4.2 Half Cells
4.2.1 Cells can also be set up by connecting two half cells together
4.2.2 A half cell consists of a metal in a solution of its own ions
4.2.3 INSERT IMAGE HERE
4.3 Rechargeable Batteries
4.3.1 Normal batteries go out of charge because the chemicals inside have been used up.
4.3.1.1 With rechargeable batteries the radox is reversable
4.3.2 Passing an electrical current through the battery forces the radox reaction into reverse
4.4 Fuel Cells
4.4.1 With a fuel cell chemicals constantly flow into the cell so it will never go flat
4.4.1.1 As long as the chemicals flow into the cell the electricity flows out of the cell
4.4.2 No Carbon Dioxide is produced so no pollution is created
4.4.3 Fuel cells need a source of hydrogen - obtained by electrolysis of water - and of oxygen - obtained from the air
