Burning Hydrocarbons
Chemistry: AQA GCSE Higher, topic 7.1.8
Burning Hydrocarbons
The equations for the combustion (burning) of hydrocarbons depend on the amount of oxygen that is available.
Burning with plenty of oxygen
- The combustion (burning) of hydrocarbons when there is a good air supply involves:
- The release of energy.
- The oxidation of carbon and hydrogen to create carbon dioxide and water.
Burning with a lack of oxygen
- If alkanes are burned without enough oxygen, then carbon monoxide can be created:
- 2C + O2 → 2CO
- Carbon monoxide is a gas with the following properties:
- Colourless
- Toxic
- Odourless
