315441 The oxidation number of \(\mathrm{Mn}\) in the product formed on strongly heating \(\mathrm{Mn}_{2} \mathrm{O}_{7}\) is ____.

315442 Which of the following options are correct for the reaction
\(2\left[\mathrm{Au}(\mathrm{CN})_{2}\right]_{(\mathrm{aq})}^{-}+\mathrm{Zn}_{(\mathrm{s})} \rightarrow\) \(2 \mathrm{Au}_{(\mathrm{s})}+\left[\mathrm{Zn}(\mathrm{CN})_{4}\right]_{(\mathrm{aq})}^{2-}\)

(B) Displacement reaction
(C) Decomposition reaction
(D) Combination reaction
Choose the correct answer from the options given below:

315443 Which of the following is not metal displacement?

315444 Assertion :
When white \(\mathrm{P}_{4}\) reacts with caustic soda, the products are \(\mathrm{PH}_{3}\) and \(\mathrm{NaH}_{2} \mathrm{PO}_{2}\). This reaction is an example of disproportionation reaction.
Reason :
In disproportionation reaction, the same substance may act simultaneously as an oxidising agent and as a reducing agent.

315445 Assertion :
\(\mathrm{I_{2} \rightarrow \mathrm{IO}_{3}^{-}+I^{-}}\)
This reaction is a disproportionation reaction.
Reason :
Oxidation number of I can vary from \({\rm{ - 1}}\,\,{\rm{to}}\,\,{\rm{ + 7}}{\rm{.}}\)
