Zinc granules on treating with an acid X, form the zinc sulphate `(ZnSO_4)` salt along with the evolution of a gas Y which burns with a pop sound when brought near to a burning candle. Identify the acid X and gas evolved Y.

Options

A. X-Sulphuric acid and Y - Oxygen gas
B. X-Hydrochloric acid and Y - Oxygen gas
C. X - Sulphuric acid and Y- Hydrogen gas
D. X-Hydrochloric acid and Y - Hydrogen gas

Explanation

To solve the question, we need to identify the acid (X) and the gas (Y) that are involved in the reaction between zinc granules and the acid, which produces zinc sulfate (ZnSO₄) and a gas that burns with a pop sound.

### Step-by-Step Solution:

1. **Identify the Reaction**:
- Zinc granules (Zn) react with an acid to produce zinc sulfate (ZnSO₄) and a gas.
- The general reaction can be represented as:
\[ \text{Zn} + \text{Acid} \rightarrow \text{ZnSO}_4 + \text{Gas} \]

2. **Determine the Product**:
- The product formed is zinc sulfate (ZnSO₄). The sulfate ion (SO₄²⁻) indicates that the acid must contain sulfate.

3. **Identify the Acid**:
- The only common acid that produces sulfate ions is sulfuric acid (H₂SO₄).
- Therefore, the acid (X) is sulfuric acid (H₂SO₄).

4. **Identify the Gas**:
- The reaction of zinc with sulfuric acid produces hydrogen gas (H₂) as a byproduct.
- The reaction can be summarized as:
\[ \text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2 \uparrow \]

5. **Characteristics of the Gas**:
- Hydrogen gas (H₂) burns with a pop sound when ignited, which matches the description of gas Y.

6. **Final Identification**:
- Thus, we conclude that:
- Acid (X) = Sulfuric Acid (H₂SO₄)
- Gas (Y) = Hydrogen Gas (H₂)

### Final Answer:
- Acid X is Sulfuric Acid (H₂SO₄).
- Gas Y is Hydrogen Gas (H₂).
