Solution

Q.
The following reaction is an example of a:

$4 N H_{3} (g) + 5 O_{2} (g) ⟶ 4 N O (g) + 6 H_{2} O (g)$

(i) Displacement reaction
(ii) Combination reaction
(iii) Redox reaction
(iv) Neutralisation reaction

1 (i) and (iv)

2 (ii) and (iii)

3 (i) and (iii)

4 (iii) and (iv)

Ans.
(3)

The given reaction is an example of displacement and redox reaction since oxygen replaces hydrogen from the ammonia molecule leading to the formation of NO. Similarly, $O_{2}$ is getting reduced in the reaction and ammonia is getting oxidised. Thus, a redox reaction takes place in this case. reaction.
Therefore, the below reaction is both the displacement and the redox reaction.
$4 N H_{3} (g) + 5 O_{2} (g) ⟶ 4 N O (g) + 6 H_{2} O (g)$
