Answer 2

Answer:

Hii mates

Explanation:

N3 +3H2 -------> 2NH3

         

 :N:. (here is three dots)+ :.N: (two nitrogen atom)

     

:N:. :.N:  ( This combine together and become triple bond)

                              H↓

:N:. + 3Hx -------->  :N-H

                               H↑  (Ammonia molecule )
