Question

The major products of the following reaction,

ZnS(s) + O₂(g) \(\overset{Heat}{\longrightarrow}\) ……… are

(a) ZnO and SO₂

(b) ZnSO₄ and SO₃

(c) ZnSO₄ and SO₂

(d) Zn and SO₂

Answer 1

Answer is : (a) ZnO and SO₂

This process is known as roasting where the sulphide ore is heated in a regular supply of air to give its oxide form at a temperature below the melting point of the metal.
