The correct Answer is:
`0003`
`NH_(4)NO_(3) overset(Delta) rarr N_(2)O+2H_(2)O`
`NH_(4)NO_(2) overset(Delta)rarr N_(2)+2H_(2)O`
`CH_(3)COONH_(4) overset(Delta) rarrCH_(3)-overset(O) overset(||)(C)-NH_(2)+H_(2)O`
`(NH_(4))_(2)CO_(3) overset(Delta) rarr2NH_(3)+H_(2)O+CO_(2)`
`NH_(4)IO_(3) overset(Delta) rarrN_(2)+I_(2)+O_(2)+H_(2)O`
`(NH_(4))_(2)Cr_(2)O_(7) overset(Delta) rarr N_(2)+Cr_(2)O_(3)+4H_(2)O`
`(NH_(4))_(3)PO_(4) overset(Delta) rarr NH_(3)+P_(2)O_(5)+H_(2)O`
