Write the balanced equations for the reactions when
(i). Potassium permanganate interacts with manganese dioxide in the presence of potassium hydroxide.
(ii). Potassium ferrocyanide is heated with concentrated sulphuric acid.

Explanation

Let's break down the reactions step by step and write the balanced equations for both scenarios.

### (i) Potassium permanganate interacts with manganese dioxide in the presence of potassium hydroxide.

1. **Identify the Reactants**:
- Potassium permanganate (KMnO4)
- Manganese dioxide (MnO2)
- Potassium hydroxide (KOH)
