The reaction of  $H_{2}S$ with   $H_2{O}_2$ is an example of _____________ reaction

The reaction of ${\mathrm{H}}_2\mathrm{S}$ with ${\mathrm{H}}_2{\mathrm{O}}_2$ is an example of _____________ reaction.

A solution of ${\mathrm{H}}_2{\mathrm{O}}_2$​ is diluted to $10$ times of its initial volume. $20 \mathrm{mL}$ of this diluted solution requires $10 \mathrm{mL}$ of $0.2\mathrm{N} {\mathrm{KMnO}}_4$ for complete oxidation. The volume strength of original ${\mathrm{H}}_2{\mathrm{O}}_2$​ solution is

$10 \mathrm{mL}$ of a mixed solution of ${\mathrm{Na}}_2{\mathrm{CO}}_3$ and ${\mathrm{NaHCO}}_3$ required $2.5 \mathrm{mL}$ of $\frac{\mathrm{M}}{10} {\mathrm{H}}_2{\mathrm{SO}}_4$ when titrated with phenolphthalein as indicator. But when methyl orange was added, a second endpoint was observed on further addition of $2.5 \mathrm{mL}$ of $0.2\mathrm{M} {\mathrm{H}}_2{\mathrm{SO}}_4$. Calculate the amount of ${\mathrm{Na}}_2{\mathrm{CO}}_3$ and ${\mathrm{NaHCO}}_3$ in the one litre solution. 

$9.8 \mathrm{g}$ of ${\mathrm{FeSO}}_4{\left({\mathrm{NH}}_4\right)}_2{\mathrm{SO}}_4·{\mathrm{xH}}_2\mathrm{O}$ was dissolved in $250 \mathrm{mL}$ of its solution. $20 \mathrm{mL}$ of this solution required $20 \mathrm{mL}$ of ${\mathrm{KMnO}}_4$ solution, containing $3.53 \mathrm{g}$ of $90\%$ pure ${\mathrm{KMnO}}_4$ dissolved per litre. Calculate $\mathrm{x}$.

Round-off the answer to the nearest integer.

$1.5 \mathrm{gm}$ of $\mathrm{KI}$ is reacted with excess of ${\mathrm{KIO}}_3$ to produce ${\mathrm{I}}_2$ which is reacted with ${\mathrm{Na}}_2{\mathrm{S}}_2{\mathrm{O}}_3$ in basic medium, where ${\mathrm{Na}}_2{\mathrm{S}}_2{\mathrm{O}}_3$ converts to ${\mathrm{SO}}_4^{2-}$.  If the strength of ${\mathrm{Na}}_2{\mathrm{S}}_2{\mathrm{O}}_3$ is $\frac{\mathrm{M}}{10}$, then the volume of ${\mathrm{Na}}_2{\mathrm{S}}_2{\mathrm{O}}_3$ needed to reach equivalence point is:
