Q. Which of the following(s) when heated give nitrogen gas?
A) (NH_{4})_{2}Cr_{2}O_{7}
B) Ba (N_{3})_{2}
C) NH_{4}NO_{3}
D) Both a and b
Explanation
(d)
(NH_{4})_{2}Cr_{2}O_{7}$\ \overset{\mathrm{\Delta}}{\rightarrow}$N_{2} + Cr_{2}O_{3} + 4H_{2}O
Ba(N_{3})_{2}$\ \overset{\mathrm{\Delta}}{\rightarrow}$3N_{2} + Ba
NH_{4}NO_{3}$\ \overset{\mathrm{\Delta}}{\rightarrow}$N_{2}O + 2H_{2}O
