Stogs Crude Oil Revision

Fossil fuels (e.g. coal, oil and gas) are:

• renewable

• non-renewable

• finite

• not finite

Crude oil is made up of:

• Ethane

• Butane

• A mixture of different hydrocarbons

• Extremely large hydrocarbons which are broken up once extracted

The general formula of the alkanes is:

• CnH2n

• CnH2n-2

• CnH2n+2

• C2nHn

A fraction of crude oil is made up of:

• Hydrocarbons of similar chain lengths

• Numbers

• Large hydrocarbons

• Alkenes only

Different fractions in crude oil are separated by:

• Cracking

• Fractional Distillation

• Filtration

• Crystalisation

Shorter hydrocarbons have:

• Higher boiling points

• Lower boiling points

Gases/LPG are used for:

• Fuel in cars

• Fuel for large ships

• Roof and road surfacing

• Domestic heating and cooking
