MCQ
Nitrogen gas is obtained by thermal decomposition of .... .
- A$Ba \left( NO _{3}\right)_{2}$
- ✓$Ba \left( N _{3}\right)_{2}$
- C$NaNO _{2}$
- D$NaNO _{3}$
✓
Answer
Correct option: B.
$Ba \left( N _{3}\right)_{2}$
b
$Ba \left( N _{3}\right)_{2} \rightarrow Ba +3 N _{2}$
$Ba \left( N _{3}\right)_{2} \rightarrow Ba +3 N _{2}$
