MCQ
The compound(s) which have $-O-O-$ bond(s) is/are
- A$BaO_2$
- B$Na_2O_2$
- C$CrO_5$
- ✓All of the above
✓
Answer
Correct option: D.
All of the above
d
$\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{Na}_{2} \mathrm{CO}_{3} \rightarrow \mathrm{CaCO}_{3}+2 \mathrm{NaOH}$
$\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{Na}_{2} \mathrm{CO}_{3} \rightarrow \mathrm{CaCO}_{3}+2 \mathrm{NaOH}$
$6 \mathrm{NaOH}+4 \mathrm{S} \rightarrow 2 \mathrm{Na}_{2} \mathrm{S}+\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}+3 \mathrm{H}_{2} \mathrm{O}$
$\mathrm{C}$ is $\mathrm{Na}_{2} \mathrm{S}_{2} \mathrm{O}_{3}$ which is used in photography.
$\mathrm{A}$ is $\mathrm{Ca}(\mathrm{OH})_{2}$
$\mathrm{B}$ is $\mathrm{NaOH}$

Two $5$ molal solutions are prepared by dissolving a non-electrolyte, non-volatile solute separately in the solvents $X$ and $Y$. The molecular weights of the solvents are $M_X$ and $M_Y$, respectively where $M_X\, = \frac{3}{4} M_Y$. The relative lowering of vapour pressure of the solution in $X$ is $''m''$ times that of the solution in $Y$. Given that the number of moles of solute is very small in comparison to that of solvent, the value of $''m''$ is
