#1
Front (Question)

Crude oil

Back (Answer)

A complex mixture of hydrocarbons- a non-renewable resource

#2
Front (Question)

How is crude oil formed

Back (Answer)

Underground over millions of years (at high temperatures and pressures), from the buried remains of plants and animals

#3
Front (Question)

Hydrocarbon

Back (Answer)

Compounds which contain just carbon and hydrogen

#4
Front (Question)

Crude oil is mostly made up of which type of hydrocarbon?

Back (Answer)

Alkanes

#5
Front (Question)

Alkane formula

Back (Answer)

CnH2n+2

#6
Front (Question)

Fractions

Back (Answer)

Simpler, more useful mixtures containing hydrocarbons of similar lengths

#7
Front (Question)

How is crude oil separated into fractions

Back (Answer)

Fractional distillation

#8
Front (Question)

Describe the fractional distillation of crude oil

Back (Answer)

1- The crude oil is heated until most of it is turned into a gas, the gases then enter a fractionating colllumn and the liquid is drained off at the bottom. 2- The column has a temperature gradient so longer hydrocarbons with higher boiling points will drain out earlier than shorter hydrocarbons

#9
Front (Question)

Describe the temperature of a fractionating column used for crude oil

Back (Answer)

Hotter at the bottom and cooler at the top

#10
Front (Question)

Fractions of crude oil from top to bottom

Back (Answer)

-Gas -Petrol -Kerosene -Diesel Oil -Fuel Oil -Bitumen

#11
Front (Question)

Gases fraction use

Back (Answer)

Domestic heating and cooking

#12
Front (Question)

Petrol fraction use

Back (Answer)

Fuel for cars

#13
Front (Question)

Kerosene fraction use

Back (Answer)

Fuel for aircraft

#14
Front (Question)

Diesel Oil fraction use

Back (Answer)

Fuel in some cars and larger vehicles (e.g. trains)

#15
Front (Question)

Fuel Oil fraction use

Back (Answer)

Fuel for large ships and power stations

#16
Front (Question)

Bitumen fraction use

Back (Answer)

To surface roads and roofs

#17
Front (Question)

Why are many hydrocarbons used as fuels

Back (Answer)

They release energy in combustion reactions

#18
Front (Question)

Complete combustion of hydrocarbons

Back (Answer)

When you burn a hydrocarbon in plenty of oxygen

#19
Front (Question)

Complete combustion of hydrocarbons reaction formula

Back (Answer)

Hydrocarbon + oxygen-> carbon dioxide + water

#20
Front (Question)

Homologous series

Back (Answer)

A family of molecules which have the same general formula and share chemical properties

#21
Front (Question)

State two different homologous series of hydrocarbons

Back (Answer)

-Alkanes -Alkenes

#22
Front (Question)

What determines the fraction of crude oil a hydrocarbon is sent to

Back (Answer)

The size of it

#23
Front (Question)

Which physical properties are determined by the size of hydrocarbons

Back (Answer)

-Boiling point -Ease of ignition -Viscosity

#24
Front (Question)

How does the size of hydrocarbons affect the boiling point

Back (Answer)

Larger hydrocarbons have higher boiling points
