Question

Which of the following reactions occur when sulphur is burnt in air?

A) Sulphur dioxide gas is produced.
B) Sulphur trioxide gas is produced.
C) Sulphuric acid is produced.
D) Sulphur monoxide gas is produced.
E) Sulphur hexafluoride gas is produced.

Answer 1

Sulphur dioxide gas is produced.

Step-by-step explanation:

The correct answer is A) Sulphur dioxide gas is produced.

When sulphur is burnt in air, it reacts with oxygen to form sulphur dioxide gas. The balanced equation for this reaction is:

S+SO2=SO3

Sulphur dioxide is a colorless gas with a pungent smell. It is commonly produced during the combustion of sulphur-containing materials, such as fossil fuels and volcanic activity.
