Ammonium salts decompose quite readily on heating :
(i) Ammonium salt of weak oxidizing anion (e.g. `Cl^(-), CO_(3)^(2-), SO_(4)^(2-)`) `overset("heat")rarr` Gas X
(ii) Ammonium salt of strong oxidizing anion (e.g. `NO_(2)^(-), NO_(3)^(-), CiO_(4)^(-), Cr_(2)o_(7)^(2-) overset("heat")rarr` Gas Y/Z Identify X, Y, Z
A. `N_(2), NH_(3), N_(2)O`
B. `NH_(3), N_(2), N_(2)O`
C. `N_(2)O, NH_(3), N_(2)`
D. `NO, NH_(3), N_(2)O`
