Complete and Incomplete combustion
- Complete combustion is when there is excess oxygen while you are buying something
- 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
- A hydrocarbon is a molecule that contains hydrogen and carbon. It always produces oxygen when reacted with something
- 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
