Question

The following reaction is an example of a

4NH3

(g) + 5O2

(g) → 4NO(g) + 6H2O(g)

(i) displacement reaction

(ii) combination reaction

(iii) redox reaction

(iv) neutralisation reaction

(a) (i) and (iv) (b) (ii) and (iii)

(c) (i) and (iii) (d) (iii) and (iv)​

Answer 1

Explanation:

The correct answer is-

c .1,3 that is Displacement reaction and redox reaction.

Displacement reaction is a chemical reaction in which lesser reactive element is displaced by more reactive element.

In the given reaction, oxygen displaces hydrogen from NH3 ( ammonia) and forms NO ( nitric oxide).

Redox reaction is a chemical reaction in which oxidation ( gain of oxygen/loss of hydrogen) and reduction ( gain of hydrogen/ loss of oxygen) takes place simultaneously.  

In the given reaction, ammonia is getting oxidized and oxygen is getting reduced.

Thus, option c) is the right answer.
