Chemistry Question on Chemical bonding and molecular structure

KMnO4 decomposes on heating at 513 K to form O2 along with

A

MnO4,MnO2MnO_4^- , MnO_2

B

K2MnO4,MnO2K_2MnO_4 , MnO_2

C

KMnO4,MnO2KMnO_4 , MnO_2

D

MnO2,H2OMnO_2, H_2O

Answer

K2MnO4,MnO2K_2MnO_4 , MnO_2

Explanation

Solution

KMnO4KMnO_4 decomposes upon heating at 513 K and forms K2MnO4K_2MnO_4 and MnO2MnO_2.

2KMnO4ΔK2MnO4+O2+MnO22KMnO4 \xrightarrow{\Delta} K_2MnO_4 + O2 + MnO2

So, the Correct option is (B): K2MnO4K_2MnO_4, MnO2MnO_2
