fractional distillation

Question 1

what is crude oil

Answer 1

• an oil made from thousands of years worth of decomposition of dead matter
• consists of hydrocarbons

Question 2

hydrcarbon

Answer 2

compound that contains only hydrogen and carbon

Question 3

explain the process of fractional distillation in the context of crude oil

Answer 3

• separating a mixture using the varied boiling points of a substance
• crude oil is heated at 350 degrees and goes up the fractioning column, the substances condense depending on the length of chains within individual substances

Question 4

how does chain length change down the fractioning column

Answer 4

chain length increases

Question 5

how does flammability change down the fractioning column

Answer 5

flammability decreases

Question 6

how does boiling point change down the fractioning column

Answer 6

boiling point increases

Question 7

4 types of hydrocarbons you need to know

Answer 7

methane
ethane
propane
butane
