What is combustion?
The burning of a substance in oxygen releasing energy
What is complete combustion?
Complete combustion occurs when a hydrocarbon burns with a plentiful supply of oxygen
Products are:
Carbon dioxide
Water
What are the products of complete combustion of a hydrocarbon?
Hydrocarbon + oxygen → carbon dioxide + water
E.g. methane + oxygen → carbon dioxide + water
What is incomplete combustion?
Incomplete combustion occurs when a hydrocarbon burns with a limited supply of oxygen
Products:
Carbon monoxide
Carbon (soot)
water
What is the difference between incomplete and complete combustion?
Complete combustion has a plentiful supply of oxygen whereas incomplete combustion has a limited supply of oxygen.
Why is carbon monoxide dangerous?
Carbon monoxide is toxic because it reduces the bloods ability to carry oxygen around the body
What is soot and how is it produced?
Soot is carbon particles produced during incomplete combustion. It can be produced when there isn't enough oxygen for complete combustion.
What problems can incomplete combustion cause?
Carbon monoxide poisoning and soot particles can contribute to air poisoning and respiratory problems
