Question

in a class room discussion keerthi agreed that thermal decomposition of kclo3 is a redox reaction write that caco3 is not a redox reaction is not a redox reaction is it right substantiate​

Answer 1

Explanation:

Redox reactions are matched sets: if one species is oxidized in a reaction, another must be reduced. Keep this in mind as we look at the five main types of redox reactions: combination, decomposition, displacement, combustion, and disproportion.

Answer 2

Answer:the case of heating KClO3KClOX3

2KClO3⟶2KCl+3O2..

The oxidation state of oxygen changes from -2 to 0, while that of chlorine changes from +5 to -1. So, will such a reaction be called a disproportionation ..

Ca remains as +2

C remains as +4

and O remains as -2

So, there is no change in oxidation number, so it's not redox reaction.

Actually it is thermal decomposition reaction.
