What type of reaction is shown above?
A)
single replacement
B)
decomposition
C)
double replacement
D)
synthesis

Answer 1

Its decomposition.

Answer is B.

AB —-> A + B

Answer 2

Decomposition Reaction

Step-by-step explanation:

In the provided reaction, we can see that Ammonia is getting decomposed into Nitrogen and Hydrogen gas.

Another way to think about it is that Decomposition is nothing but one thing giving rise to 2 or more than 2 things.

Since our Ammonia is giving rise to 2 gases, this reaction is an example of Decomposition reaction
