Question

The following reaction is an example of a 4NH3(g)+5O2(g)→4NO(g)+6H2O(g) I.displacement reaction 2.combination reaction 3.redox reaction 4.neutralisation reaction a.1.,4 b .2,3 c .1,3 d.3,4

Answer 1

displacement reaction+redox reaction
option:c

Answer 2

Answer: 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.
