What do hydrocarbon fuels release when combusted

Energy

What type of reaction is combustion

Oxidation

Define combustion

The burning of fuel in oxygen to release energy

What happens in the combustion of hydrocarbons

During combustion, the carbon and hydrogen atom in the fuel react with oxygen, so are oxidised

Hydrogen atoms are oxidised into water (H20)

Carbon atoms are oxidised into Carbon Dioxide

Products of complete combustion

Water and carbon dioxide

What is incomplete combustion

Incomplete combustion occurs when there is not enough oxygen for the fuel to burn fully

What happens during incomplete combustion

Hydrogen atoms are oxidised into water

Carbon atoms do not fully oxidise

Products of incomplete combustion
