Mention the chemical reactions of sulphur with acids, dihydrogen gas and carbon element.

Reaction of sulphur with acids:

i. Sulphur reacts with hot concentrated sulphuric acid to form sulphur dioxide. The reaction is:

S + 2H₂SO₄→ 2H₂O + 3SO₂

ii. Sulphur reacts with concentrated nitric acid to form sulphuric acid. The reaction is:

S + 6HNO₃→ H₂SO₄→ 6NO₂ + 3H₂O

Reaction of sulphur with dihydrogen gas (H₂):

Sulphur reacts with dihydrogen gas to form hydrogen sulphide. The reaction is:

S + 2H₂→ 2H₂S

Reaction with carbon element:

Sulphur reacts carbon element to form carbon disulphide. The reaction is:

C+ 2S → CS₂
