Its dark, viscous, thick. Pure crude oil is not useful as it contains a lot of long chain hydrocarbons.

What is combustion and what is always formed?
This is when you break down a substance in the presence of oxygen. Carbon dioxide and water is always formed.
3 of 10
What is incomplete combustion and what is always released?
When there isn't enough oxygen and sulphur dioxide is released.

What is fractional distillation?
Crude oil is heated, it evaporates, short chain HC rises to the cooler area at the top of the colomn and condenses based on its boiling point then vaporises, long chan HC stay at bottom

what is the difference between alkanes and alkenes?
Alkanes are saturated and have single bonds and are unhealthy since it can pack more single bonds together alkenes are unsaturated and have double bonds and are healthier as it can pack less bonds.

What are the 5 harmful gases...
Nitrogen (NO) formed by car engines, triggers asthma, Sulphur dioxide (SO2) by burning coal/hydrocarbons causes acid rain, carbon dioxide by burning fossil fuels causes lung damage and releases the greenhouse effect,
7 of 10
What are the 5 harmful gases...
Carbon monoxide (CO) formed by incomplete combustion and its poisonous and can kill you as it stops blood carrying oxygen, and particulates formed by burning wood/fossil fuels and damages lungs.
8 of 10
What are the solutions to those gases?
Burn fossil fuels cleaner, use scrubbers and bio diesel.
9 of 10
Name the advantages and disadvantages of bio diesel.
Advantages are its renewable, co2 neutral, more employment and its cheap. Disadvantages are its a long process, crops are being used for fuel rather than for food, and destruction of habitat.
