complete the following equation :
(i) c+conc.`H_(2)SO_(4)rarr`
(ii) `XeF_(2)+H_(2)Orarr`

Explanation

Let's complete the given equations step by step.

### Step 1: Completing the First Equation
The first equation is:
\[ C + \text{conc. } H_2SO_4 \rightarrow ? \]

1. **Identify Reactants**: We have carbon (C) and concentrated sulfuric acid (H₂SO₄).
2. **Determine Products**: When carbon reacts with concentrated sulfuric acid, it undergoes oxidation. The products formed are carbon dioxide (CO₂), sulfur dioxide (SO₂), and water (H₂O).
