Front (Question)

What is crude oil?

Back (Answer)

Mixture of hydrocarbons

Front (Question)

What is a mixture?

Back (Answer)

2 or more substances mixed but not chemically bonded together

Front (Question)

What is the general formula for alkanes?

Back (Answer)

CnH2n+2

Front (Question)

What is a hydrocarbon?

Back (Answer)

Compound made from only carbon and hydrogen

Front (Question)

Are alkanes saturated or unsaturated?

Back (Answer)

Saturated

Front (Question)

What does the line in between C-C in a molecule show?

Back (Answer)

Covalent bond, a shared pair of electrons

Front (Question)

What method is used to separate crude oil?

Back (Answer)

Fractional distillation

Front (Question)

Describe how fractional distillation works?

Back (Answer)

Crude oil is heated to evaporate and then the different fractions are condensed because of their different boiling points

Front (Question)

As the number of carbons increase in an alkane what happens to the boiling point?

Back (Answer)

It increases

#10

Front (Question)

As the number of carbons increase in an alkane what happens to the viscosity?

Back (Answer)

It increases, gets more sticky

#11

Front (Question)

As the number of carbons increase in an alkane what happens to the flammability?

Back (Answer)

Gets less flammable

#12

Front (Question)

As the temperature of oil increases what happens to the viscosity?

Back (Answer)

Gets less viscous, more runny

#13

Front (Question)

What are the products of complete combustion of hydrocarbons?

Back (Answer)

Carbon dioxide and water

#14

Front (Question)

What are the products of incomplete combustion of hydrocarbons?

Back (Answer)

Carbon monoxide and carbon (soot)

#15

Front (Question)

If crude oil contains some sulfur what combustion product will be made?

Back (Answer)

Sulfur dioxide

#16

Front (Question)

In combustion are carbon and hydrocarbon oxidised or reduced?

Back (Answer)

Oxidised as oxygen is added

#17

Front (Question)

High temperatures may cause oxides of nitrogen what type of pollution is caused by the oxides of nitrogen and sulfur dioxide?

Back (Answer)

Acid rain

#18

Front (Question)

What effect does this pollution have on the environment?

Back (Answer)

Weathering of rocks and buildings, and changes acidity of the soil

#19

Front (Question)

Carbon dioxide causes what type of pollution?

Back (Answer)

Global warming

#20

Front (Question)

Solid particles (soot or unburnt fuel) causes what type of pollution?

Back (Answer)

Global dimming

#21

Front (Question)

Give 2 ways sulfur dioxide can be reduced?

Back (Answer)

Removing sulfur before burning of the fuel and removal of sulfur dioxide after burning

#22

Front (Question)

What are biodiesel and bioethanol made from?

Back (Answer)

Plants

#23

Front (Question)

Give two advantages and disadvantages of using hydrogen as an alternative fuel.

Back (Answer)

Made from water and renewable Storing is expensive and flammable

#24

Front (Question)

Give two advantages and disadvantages of using bioethanol as an alternative fuel.

Back (Answer)

Renewable and doesn’t produce toxic fumes Need to have the climate to grow sugar cane and it uses lot of fields that could be used for food
