Options

A. `NaN_(3) underset(Delta) rarr` ?
B. `(NH_(4))_(2)Cr_(2)O_(7) underset(Delta) rarr` ?
C. `NH_(4)Cl+Ca(OH)_(2) rarr` ?
D. `Ba(N_(3))_(2) underset(Delta) rarr` ?

Answer

C

Explanation

(a) `underset("Sodium azide") 2NaN_(3) overset (Delta) rarr 2Na+3N_(2)`
(b) `(NH_(4))_(2) Cr_(2)O_(7) overset(Delta) rarr Cr_(2) O_(3) +N_(2)+4H_(2)O`
(c ) `2NH_(4)Cl+Ca(OH)_(2) rarr CaCl_(2)+2NH_(4)OH`
(d) `underset("Barium acide") (Ba(N_(3))_(2))rarr Ba+3N_(2)`
