Answer

Let's solve the question step by step.

### Step 1: Identify what concentrated H₂SO₄ does to paper, wood, and sugar.
Concentrated H₂SO₄ chars paper, wood, and sugar by removing **water** from them.

### Step 2: Identify the alternative name for H₂SO₄.
Concentrated H₂SO₄ is also known as **oil of vitriol**.

### Step 3: Identify the process used to manufacture H₂SO₄.
H₂SO₄ is manufactured by the **contact process**.

### Step 4: Identify the nature of H₂SO₄.
H₂SO₄ is a strong **oxidizing** acid.

### Step 5: Identify the type of acid H₂SO₄ is.
H₂SO₄ is also a **diabasic** acid because it can donate two protons (H⁺ ions) in an aqueous solution.

### Final Answer:
1. H₂O
2. oil of vitriol
3. contact process
4. oxidizing
5. diabasic

### Summary of the filled blanks:
- (i) H₂O
- (ii) oil of vitriol
- (iii) contact process
- (iv) oxidizing
- (v) diabasic
