Nature's Chemistry (N5)
The key areas covered in this Unit are:
homologous series — the study of cycloalkanes and branched chain alkanes and alkenes to include their physical, chemical properties, general formulae, systematic names, structural formulae, uses, and isomers
everyday consumer products — uses of alcohols and carboxylic acids: to include their physical, chemical properties; for straight chain alcohols and carboxylic acids (C1–C8) general formulae, systematic naming, structural formulae; manufacture of esters as a use of alcohols and carboxylic acids; uses of esters
Shampoo: Activity to make shampoo, involving steam distillation to extract natural essences.
Biodiesel: A workshop based around the production and testing of Biodiesel (fatty acid ethy esters) from vegetable oil
energy from fuels — energy calculations involving Eh = cmΔt (not per mole) calculations based on balanced equations
Dynamite soap (Demo) - Exploding hydrogen/oxygen bubbles generated by the elextrolysis of water.
Piezo rockets (Demo) - making and firing mini pipette rockets for hydrogen (or perhaps another flammable gas).
Whoosh bottle (Demo) - Ignition of alcohol vapour in a 15l water bottle to produce a spectacular 'whoosh'.
Biodiesel- A workshop based around the production and testing of Biodiesel (fatty acid ethy esters) from vegetable oil. Including energy values.
