  1. Correct Answer – A
    Except for `(NH_(4))_(2)SO_(4)` which evolves `NH_(3)` upon strong heating, all other compounds decompose the produce `N_(2)` gas
    `(NH_(4))_(2)SO_(4) overset(“heat”)to 2NH_(3)+H_(2)SO_(4)`
    `(NH_(4))_(2)Cr_(2)O_(7) overset(“heat”) to N_(2)+4H_(2)O + Cr_(2)O_(3)`
    `(NH_(4))_(2)NO_(2) overset(“heat”)to N_(2)+2H_(2)O`
    `Ba(N_(3))_(2) overset(“heat”) to Ba+3N_(2)`
