Among the following compounds, which on heating do not produce `N_(2)` ?

Options

A. `(NH_4)_(2)Cr_(2)O_(7)`
B. `NH_(4)Cl+ NaNO_(2)`
C. `NH_(4)Cl+CaO`
D. `Ba(N_3)_(2)`

Answer

C

Explanation

`(NH_4)_(2)Cr_(2)O_(7) overset(triangle)(to) Cr_(2)O_(7)+N_(2)+H_(2)O`
`NH_(4)Cl+NaNO_(2) overset(triangle)(to)NH_(4)NO_(2)+NaCl`
`NH_(4)NO_(2) overset(triangle)(to)N_(2) uparrow +2H_(2)O`
`Ba(N_3)_(2)overset(triangle)(to) Ba+3N_(2) downarrow`
`2NH_(4)Cl+CaO overset(triangle)(to) CaCl_(2)+2NH_(3) uparrow +H_(2)O`.
