MCQ
The laboratory test 'tailing the mercury' is applied to identify
- A$O_2$
- B$O_3$
- C$H_2O$
- ✓$H_2O_2$
✓
Answer
Correct option: D.
$H_2O_2$
d
$\mathrm{KO}_{2}$ is used in oxygen cylinders for space and submarines. Because it absorbs $\mathrm{CO}_{2}$ and release $\mathrm{O}_{2}$
$\mathrm{KO}_{2}$ is used in oxygen cylinders for space and submarines. Because it absorbs $\mathrm{CO}_{2}$ and release $\mathrm{O}_{2}$
$4 \mathrm{KO}_{2}+2 \mathrm{CO}_{2} \rightarrow 2 \mathrm{K}_{2} \mathrm{CO}_{3}+2 \mathrm{O}_{2}$
Hence A \& C are correct.
