| LIST-I | LIST-II |
| --- | --- |
| (I) $\mathrm{H}_{2} \mathrm{O}_{2}$ | (P) $\mathrm{Mg}(\mathrm{HCO}_{3})_{2}+\mathrm{Ca}(\mathrm{OH})_{2} \rightarrow$ |
| (II) $\mathrm{Mg}(\mathrm{OH})_{2}$ | (Q) $\mathrm{BaO}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow$ |
| (III) $\mathrm{BaCl}_{2}$ | (R) $\mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{MgCl}_{2}$ |
| (IV) $\mathrm{CaCO}_{3}$ | (S) $\mathrm{BaO}_{2}+\mathrm{HCl} \rightarrow$ |
| | (T) $\mathrm{Ca}(\mathrm{HCO}_{3})_{2}+\mathrm{Ca}(\mathrm{OH})_{2} \rightarrow$ |
