321322 Out of the 5 different products formed in the following reaction, how many contains O -atom(s)? ____ .
\({\mathrm{\mathrm{KMnO}_{4}+\mathrm{Na}_{2} \mathrm{O}_{2}+\mathrm{H}_{2} \mathrm{SO}_{4} \longrightarrow}}\)

321323 Assertion :
\(\mathrm{KMnO}_{4}\) is stored in dark bottles.
Reason :
On heating with alkalies, \(\mathrm{KMnO}_{4}\) is converted to manganate.

321324 The formula mass of Mohr's salt is 392. The iron present in it is oxidised by \(\mathrm{\mathrm{KMnO}_{4}}\) in acid medium. The equivalent mass of Mohr's salt is

321325 Aqueous solution of a salt (A) forms a dense white precipitate with \(\mathrm{\mathrm{BaCl}_{2}}\) solution. The precipitate dissolves in dilute \(\mathrm{\mathrm{HCl}}\) to produce a gas (B) which decolourises acidified \(\mathrm{\mathrm{KMnO}_{4}}\) solution. A and \(\mathrm{\mathrm{B}}\) respectively are

321326 When a small amount of \(\mathrm{\mathrm{KMnO}_{4}}\) is added to concentrated \(\mathrm{\mathrm{H}_{2} \mathrm{SO}_{4}}\), a green oily compound is obtained which is highly explosive in nature. Compound may be
