During the decomposition of potassium permanganate (potassium permanganate) KMnO4, potassium manganate K2MnO4, manganese (IV) oxide MnO2 and oxygen are formed. Write down the equation for this reaction.
2KMnO4 = K2MnO4 + MnO2 + O2 ↑
To what type of reactions on the basis of absorption or release of heat are the reactions of tasks 2 and 3? To endothermic reactions, that is, during the reaction, heat is absorbed.
