`KMnO_4 overset("heat")(to) ………… + MnO_2 + …………..`

Explanation

To solve the question regarding the thermal decomposition of potassium permanganate (KMnO4), we will follow these steps:

### Step 1: Understand the thermal decomposition of KMnO4
When potassium permanganate (KMnO4) is heated, it undergoes thermal decomposition. This means that it breaks down into simpler substances.

### Step 2: Identify the products of the reaction
Upon heating KMnO4, the products formed are:
- Potassium manganate (K2MnO4)
