NH3 can′t be obtained by :

NH4NO3 and NH4NO2 both contain oxidising anions and thus gives N2O or N2 not ammonia.NH4NO3 N2O + 2H2O ; NH4NO2 N2 + H2O

Question

NH₃ can′t be obtained by :

A.heating of NH₄NO₃ or NH₄NO₂

B.heating of NH₄Cl or (NH₄)₂ CO₃

C.heating of NH₄NO₃ with NaOH

D.reaction of AIN or Mg₃N₂ or CaCN₂ with H₂O

NH₄NO₃ and NH₄NO₂ both contain oxidising anions and thus gives N₂O or N₂ not ammonia.
NH₄NO₃ N₂O + 2H₂O ; NH₄NO₂ N₂ + H₂O
