When \(3.92 \mathrm{~g}\) of Mohr salt is dissolved in \(100 \mathrm{~mL}\) of water, and titrated against \(\mathrm{KMnO}_4\) solution, \(20 \mathrm{~mL}\) of this solution required \(18 \mathrm{~mL}\) of \(\mathrm{KMnO}_4\) for complete o...

Identify the oxidation reaction in which acidified \(\mathrm{KMnO}_4\) is required

In the reaction,

\(2 \mathrm{~S}_2 \mathrm{O}_3^{2-}+\mathrm{I}_2 \rightarrow \mathrm{S}_4 \mathrm{O}_6^{2-}+2 \mathrm{I}^{-}\)

When 1 mole of \(\mathrm{O}_2\) and 1 mole of ammonia are made to react in the reaction,
\(4 \mathrm{NH}_3(\mathrm{~g})+5 \mathrm{O}_2(\mathrm{~g}) \rightarrow 4 \mathrm{NO}(\mathrm{g})+6 \mathrm{H}_2 \mathrm{O}(\mathrm{g})\)

The correct option for free expansion of an ideal gas under adiabatic condition is:

At Constant volume, the heat required to raise the temperature of \(4.48 \mathrm{~L}\) of an ideal gas at STP by \(15^{\circ} \mathrm{C}\) is 12.0 calories.
