Zinc reacts with hot and concetrated `H_(2)SO_(4)` to give

Options

A. `H_(2)`
B. `SO_(2)`
C. `SO_(3)`
D. `H_(2)S`

Explanation

To solve the question regarding the reaction of Zinc with hot and concentrated sulfuric acid (H₂SO₄), we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are Zinc (Zn) and concentrated sulfuric acid (H₂SO₄).

### Step 2: Write the Chemical Equation
When Zinc reacts with hot and concentrated sulfuric acid, it undergoes a reaction that can be represented by the following chemical equation:
\[ \text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2 \]
In this reaction, Zinc (Zn) reacts with sulfuric acid (H₂SO₄) to form Zinc sulfate (ZnSO₄) and hydrogen gas (H₂).

### Step 3: Analyze the Products
From the equation, we can see that the products of the reaction are:
1. Zinc sulfate (ZnSO₄)
2. Hydrogen gas (H₂)

### Step 4: Identify the Gas Produced
The question specifically asks for the gas produced in this reaction. From our chemical equation, it is clear that the gas produced is hydrogen (H₂).

### Conclusion
Thus, when Zinc reacts with hot and concentrated sulfuric acid, it produces hydrogen gas.

### Final Answer
The correct answer is: **H₂ (Hydrogen gas)**.
