When sulphur is burned in air, what is the chemical equation for the reaction?
S + O₂ → SO₂.
S + H₂O → H₂S + O₂.
S + 2O₂ → SO₄.
S + N₂ → SN₂.
Which of the following best describes the physical properties of sulphur dioxide?
Colourless gas with a pungent, suffocating smell, denser than air.
Green solid with no smell, lighter than air.
Yellow gas with a rotten egg smell, less dense than air.
Blue liquid with a sweet smell, insoluble in water.
When concentrated sulphuric acid reacts with copper, what gas is produced?
Oxygen gas.
Hydrogen sulphide gas.
Hydrogen gas.
Sulphur dioxide gas.
What is the main reason why sulphur is used in the vulcanization of rubber?
To make it less elastic.
To improve its strength and elasticity.
To make it colourful.
To make it more soluble in water.
Sulphuric acid is referred to as the 'King of Chemicals' because:
It is produced in very large quantities and used in many industries.
It is the strongest acid known.
It is highly corrosive.
It has a very low boiling point.
