GCSE Chemistry Revision
The process of Combustion - all you need to know for the new syllabus!
For all examination boards including, WJEC, OCR, AQA and Edexcel, it is important that you know about the process of combustion as it is likely to come up in your examination. Combustion is an important process as it is linked to the production of energy.
Let’s take a look at some of the key facts about combustion:
Combustion occurs when a fuel burns in plenty of air - energy is released as heat, but some is also wasted as light
Complete combustion means that there is sufficient oxygen for the fuel to fully react
Fuels such as natural gas and petrol contain hydrocarbons. When a hydrocarbon burns the carbon oxidises to form carbon dioxide and the hydrogen oxidises to water
When there is not sufficient oxygen for the fuels to burn completely, it is called incomplete combustion. Water is still produced but so is carbon monoxide and carbon. Carbon monoxide is extremely dangerous to health so house boilers are regularly serviced to ensure that complete combustion is taking place
When many fossil fuels are burned they produce sulfur dioxide which produces the effect of acid rain
When fuel is burned in vehicle engines they produce nitrogen dioxide which also contribute to acid rain
Acid rain is damaging to the environment
These are some of the key things you need to know about combustion. To learn more about energy, energy production and energy transfers, take a look at the following songs:
These will make sure you are prepared for your GCSE Chemistry examinations.
