​ (a)   formed from the remains of prehistoric marine microorganisms that, over millions of years, were transformed by heat and pressure into ​ (b)   and other organic compounds. This mixture, known as crude oil, can be separated into useful organic compounds through ​ (c)   .

​ (d)   is a compound that is used as a starting material for many other organic compounds, source from plants. It can be used to make the polymer, ​polyethene. A polymer is commonly known as a ​ (e)   .

Match the definitions with their term

• Hydrocarbon

• Resources that are naturally replenished or regenerated over short timescales and are sustainable for long-term use.

• Non-Renewable Resource

• The branch of chemistry that studies organic compounds

• Organic Molecule

• A molecule made of carbon and hydrogen

• Organic Chemistry

• Resources that cannot be replenished or regenerated within a human timescale. These are finite and will eventually run out.

• Renewable

• Chemical compounds that contain carbon atoms bonded to hydrogen atoms, and often other elements like oxygen, nitrogen, and sulfur.

Which of the examples of non-renewable resources?

• Coal

• Crude Oil

• Wind

• Biomass (fuel from plants)

Which of the examples of non-renewable resources?

• Coal

• Crude Oil

• Wind

• Biomass (fuel from plants)

Fractional distillation separates ​ (a)   by ​ (b)   crude oil to vaporize it (become a gas), then ​ (c)   the vapors in a fractionating column, where hydrocarbons condense (become liquids) at different heights based on their boiling points, with ​ (d)   molecules condensing at the top and ​ (e)   molecules condensing at the bottom.
