Question 8(iii)Convert the following reactions into a balanced chemical equation:(a) Ammonia to nitric oxide using oxygen and platinum catalyst.(b) Sodium hydroxide to sodium sulphate using sulphuric acid.(c) Ferrous sulphide to hydrogen sulphide using hydrochloric acid.

Question

Accepted Answer

(a) Ammonia to nitric oxide using oxygen and platinum catalyst.

$4\text{NH}_3 + 5\text{O}_2 \xrightarrow[800 \degree \text{C}]{\text{Pt}.} 4\text{NO} + 6\text{H}_2\text{O} + \Delta$

(b) Sodium hydroxide to sodium sulphate using sulphuric acid.

2NaOH + H₂SO₄ ⟶ Na₂SO₄ + 2H₂O

(c) Ferrous sulphide to hydrogen sulphide using hydrochloric acid

FeS + 2HCl ⟶ FeCl₂ + H₂S
