Question 2

How is crude oil separated?

Answer 2

Fractional distillation

Question 3

Answer 3

Crude oil is heated and they boil off at different boiling points, they condense into fractions, the lower boiling points have fractions at the top and higher boiling points have fractions at the bottom

Question 4

What are two types of alternative fuels?

Answer 4

Ethanol: from oil or fermentation

Question 5

What is cracking?

Answer 5

Question 7

How is a polymer made?

Answer 7

Alkenes are opened up to form chains, the chain is called a polymer

Question 8

How do we make ethanol as a renewable fuel?

Answer 8

From crude oil
Crude oil -> fractional distillation -> cracking -> Ethene -> ethanol
From sugar
Sugar is dissolved in water and yeast is added. The yeast converts the sugar into ethanol

Question 9

What is an emulsifier?

Answer 9

Chemicals that can help break fats up

Question 10
