cannot be prevented
Which of the following items will rust?
A plastic bottle
A gold ring
An iron bridge
A cardboard box
The picture shows an investigation into the conditions required for rusting. What is the purpose of the layer of oil in test tube B?
To absorb moisture
To prevent oxygen getting into the water
To prevent carbon dioxide from being released
To keep the water in the test tube
Look at the picture. From what you see, choose which things are needed for rusting to occur.
water only
oxygen only

water and oxygen
An experiment has been carried out by a group of pupils. The results of the experiment are recorded in Table 2.
What can be concluded from this experiment?
Nail X did not rust because exposed to the air and water.
Nail Y rust because exposed to the air and water.
Nail X did not rust because exposed to the oil layer.
Nail Z did not rust because exposed to water.
Which nails will rust after one week?
A
B
C

What is the main component in natural gas?
carbon dioxide
methane
nitrogen
oxygen
What is the gas required in the combustion of fossil fuels to produce energy?

Why can crude oil be separated into different fractions?
The fractions have different colours.
The fractions have different boiling points.
The fractions have different solubilities in water.
The fractions are in different physical states at room temperature.
Which sentence about fractional distillation of crude oil is true?
Natural gas is collected at the bottom of the fractionating column.
The hydrocarbon with the lowest boiling point remains in the furnace.
The fractions are collected one after the other during the process.
Shorter hydrocarbons are collected near the top of the fractionating column.
The diagram shows a fractionating column used to separate crude oil. Which of the following statements is correct?
Fraction X is more viscous than fraction Z.
Fraction X is less flammable than fraction Y.
Fraction Y has a lower boiling point than fraction Z.
Fraction Y contains molecules of larger molecular masses than fraction Z.
Biofuels are fuels made from plants and animals. One example is bioethanol, which can be produced by fermenting sugarcane. Carbon dioxide gas is given off during the production of bioethanol, as well as when it is burnt as a fuel. However, this may not result in an overall increase in the amount of carbon dioxide in the atmosphere.
Which statement explains this advantage of bioethanol as a fuel?
A similar amount of carbon dioxide is removed from the atmosphere due to photosynthesis in the sugarcane plants.
A similar amount of carbon dioxide is used up by the sugarcane plants during respiration.
Bioethanol is a renewable resource.
The combustion of bioethanol produces less carbon dioxide per carbon atom.
What is a hydrocarbon?
a mixture of hydrogen and carbon
a compound made up of hydrogen, carbon and oxygen atoms
a compound made up of hydrogen and carbon atoms only
a mixture of hydrogen, carbon and oxygen atoms
Which gas is produced during incomplete combustion?
carbon monoxide
carbon dioxide
nitrogen
oxygen

Neutralisation
Displacement
Where do short chain hydrocarbons collect?
At the top
In the middle
At the bottom
What is natural gas mainly made up of?
