To solve the problem of determining what substances are formed when potassium permanganate (\(KMnO_4\)) decomposes upon heating at 513 K, we need to understand the chemical decomposition reaction involved.
When \(KMnO_4\) is heated, it decomposes into potassium manganate (\(K_2MnO_4\)), manganese dioxide (\(MnO_2\)), and oxygen gas (\(O_2\)). The balanced chemical reaction for this decomposition is given by:
| \(2KMnO_4 \rightarrow K_2MnO_4 + MnO_2 + O_2\) |
Let's analyze the options:
The only option that correctly represents the components formed by the decomposition of \(KMnO_4\) is:
Thus, the correct answer is:
\(KMnO_4\) decomposes upon heating at 513 K and forms \(K_2MnO_4\) and \(MnO_2\).
\(2KMnO4 \xrightarrow{\Delta} K_2MnO_4 + O2 + MnO2\)
So, the Correct option is (B): \(K_2MnO_4\), \(MnO_2\)

Statement II : Compounds of group 15 elements in +3 oxidation states readily undergo disproportionation reactions.
In the light of above statements, choose the correct answer from the options given below
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
