Options:
A) $ N{H_4}N{O_2} $
B) $ {{\text{(N}{H_4}\text{)}}_2}S{O_4} $
C) $ \text{Ba(}{N_3}{{)}_2} $
D) $ {{\text{(N}{H_4}\text{)}}_2}C{r_2}{O_7} $
Show Answer
Answer:
Correct Answer: B
Solution:
- $ {{\text{(N}{H_4}\text{)}}_2}S{O_4}\xrightarrow{\Delta }N{H_3}\text{+}{H_2}S{O_4} $ $ Ba{{(N _3)}_2}\xrightarrow{\Delta }Ba+3N _2\uparrow $ $ {{(NH _4)}_2}Cr _2O _7\xrightarrow{\Delta }N _2\uparrow +\underset{(Green)}{\mathop{Cr _2O _3}},+4H _2O $ $ NH _4NO _2\xrightarrow{\Delta }N _2\uparrow +2H _2O $
