The compound (s) which generate (s) `N_(2)` upon thermal decomposation is (are) :
A. `NH_(4)NO_(3)`
B. `(NH_(4))_(2)CO_(7)`
C. `Ba(N_(3))_(2)`
D. `Mg_(2)N_(2)`
A. `NH_(4)NO_(3)`
B. `(NH_(4))_(2)CO_(7)`
C. `Ba(N_(3))_(2)`
D. `Mg_(2)N_(2)`
Correct Answer – B::C
Both `(NH_(4))_(2)Cr_(2)O_(7) ” and ” Ba(N_(3))_(2)` decompose below `300^(@)C`.
`NH_(4)_(2)Cr_(2)O_(7) overset(“heat”)to N_(2)+Cr_(2)O_(3)+H_(2)O`
`Ba(N_(3))_(2) overset(“heat”)to Ba+3N_(2)`
Both `NH_(4)NO_(3)` and `Mg(NO_(3))_(2)` donot decompose below `300^(@)C`. They decompose at higher tempertures.
