Write the balanced chemical equations for the following:
i. Sodium bromate reacts with flurine in the presence of an alkalil.
ii. Sodium chlorate chlorate rects with sulphur dioxide in dilute sulphuric acid medium.

Explanation

To solve the question, we need to write balanced chemical equations for the two reactions provided. Let's break it down step by step.

### Step 1: Write the equation for the reaction of sodium bromate with fluorine in the presence of an alkali.

1. **Identify the reactants and products**:
- Reactants: Sodium bromate (NaBrO3) and fluorine (F2) in the presence of sodium hydroxide (NaOH).
- Products: Sodium perbromate (NaBrO4), sodium fluoride (NaF), and water (H2O).
