Complete and Incomplete combustion

Complete and Incomplete combustion

1. Complete combustion is when there is excess oxygen while you are buying something

2. Incomplete combustion is when there is not enough oxygen when you burn things.

   • Because the fuel is not fully oxidised it causes CO to be made
   • You can't balance these equations unless you don't include the particulates

3. A hydrocarbon is a molecule that contains hydrogen and carbon. It always produces oxygen when reacted with something

4. Intermolucular bonds

   • They are when there is an attraction between molecules.
     • To turn a liquid into gas you need to break the intermolucular bond.
       • The actual bonds between the molecule aren't broken
         • The higher the melting point the stronger the intermolecular bonds
           • Turning a solid into a gas
             • For this to take place the intermolecular bonds have to weaken so that the molecules can move freely
               • The length of a molecule can affect this
                 • The bigger the molecule the stronger the intermolecular bond.
                   • How much the molecules are attracted towards each other
                     • Size of the atoms involved
                       • Surface area of molecules
