C - Fractional Distillation Of Crude Oil

Question 1

Crude oil is formed from the buried remains of…

Answer 1

Animals and plants

Question 2

Crude oil is a f_____ ____

Answer 2

Fossil fuel

Question 3

Crude oil is a mixture of many different ________, most of which are ______________ molecules

Answer 3

Question 4

What’s a mixture?

Answer 4

Two or more elements or compounds that aren’t chemically bonded together

Question 5

Hydrocarbons are basically just made of _______ and _________!

Answer 5

Carbon and hydrogen

Question 6

Why is it beneficial that there are no chemical bonds (mixture) between the hydrocarbon molecules?

Answer 6

Because they will keep their original properties and so the mixture will have a mixture of the properties from the separate parts. Allowing you to perform fractional distillation.

Question 7

How can crude oil be split up into separate fractions?

Answer 7

Fractional distillation

Question 8

What’s the process of fractional distillation?

Answer 8

1. Heated crude oil piped in at the bottom.
2. The vaporised oil rises up the column.
3. The various fractions are constantly tapped off at the different levels where they condense.

Question 9

Is crude oil running out?

Answer 9

YES
