Crude oil and fuels

Question 1

Main forms of fossil fuels?

Answer 1

Coal, oil and natural gas

Question 2

Non-renewable means?

Answer 2

non replaceable as they are formed over a very very long time period

Question 3

How do we create fuels from crude oil?

Answer 3

Fractional distilation

Question 4

What are the products of fractional distillation?

Answer 4

different length hydrocarbons

Question 5

As the amount of carbon atoms increases in hydrocarbons, the viscosity?

Answer 5

increases

Question 6

As the amount of carbon atoms increases in hydrocarbons, the boiling point?

Answer 6

increases

Question 7

Answer 8

increases

Question 9

Formula for Alkanes?

Answer 9

CnH2n+2

Question 10

What bond does an alkane have?

Answer 10

Covalent

Question 11

Alkanes in order?

Answer 11

Methane CH4
Ethane C2H6
Propane C3H8
Butane C4H10

Question 12

How can we shorten hydrocarbons?

Answer 12

Cracking by using heat and a catalyst of clay

Question 13

What is special about alkenes?

Answer 13

They contain double bonds and are unsaturated

Question 14

How can we test double bonds?

Answer 14

Mixing with bromine water

Question 15

Alkenes general formula?

Answer 15

CnH2n

Question 16

Alkenes in order?

Answer 16

Ethene C2H4
Propene C3H6
Butene C4H8
Pentene C5H10

Question 17

What are polymers?

Answer 17

We can turn alkenes into polymers by use of the reaction addition polymerisation which is the use of heat and pressure. This is just a long line of alkenes joined.

Question 18

What is the envirometal problem with polymers?

Answer 18

Polymers are not biodegradable because bacteria cannot break down plastics
