Hydro-Carbons
| Term | Definition |
|---|---|
| Hydrocarbons | Made by Hydrogen & Carbon Atoms only |
| Physical Properties: Hydrocarbons | Size |
| Viscosity: Hydrocarbons | Increases as Molecular Increases |
| Boiling Point: Hydrocarbons | Turns Gas as Molecular Increases Size |
| Hydrocarbons, Combustion | Releases Energy, useful Fuel |
| During Combustion C & H in fuels | Oxidised |
| Complete Combustion Hydrocarbon | Carbon Dioxide + Water |
| Hydrocarbons can be broken down | To Useful, more In Demand |
| Cracking (Stage 1) | Large Hydrocarbons heated, vaporise it |
| Cracking (Stage 2) | Hydrocarbon vapour passed over Hot Catalyst |
| Steam Cracking (Stage 1) | Large Hydrocarbons Heated, in order to vaporise them |
| Steam Cracking (Stage 2) | Mixed, water vapour, Heated (High temp) |
| Products of Cracking | AlkEnes & Smaller AlkAnes |
| Use of Alkenes | Alcohols |
| Bromine | Used to test for Alkenes |
| Bromine water + Alkenes (Orange) | Colourless Result |
| Common Alkali's | Hydroxides, Sodium, Potassium & Calcium |
| Acid + Alkali --> | Salt + Water |
| Acid + Metal Oxide --> | Salt + Water |
| Acid + Carbonate --> | Salt + Carbon Dioxide +Water |
| Neutralisation Reaction | |
| Thermosetting Plastics | H Melting Point Strong Covalent Bonds, Rigid Structure |
| Uses of Thermosetting Plastics | Glues |
| Thermosoftening Plastics | L Melting Point, Weak intermolecular forces, Stretchy |
| Uses of Thermosoftening Plastics | Clothing |
