Fractional Distilation

Question 1

How is Crude Oil made

Answer 1

microscopic plants and animals die and fall to the sea bed
layers of sand and mud form on top
pressure and high temperatues cause oil to form

Question 14

why is fractional distillation important?

Answer 14

fraction shave differnt uses and some are more useful and in higher demand than others

Question 15

Hydrocarbon

Answer 15

molecule containing only carbon and hydrogen

Question 16

Saturated Hydrocarbon

Answer 16

contains only carbon - carbon single bonds

Question 17

Unsaturated Hydrocarbons
