Fenton's reagent is X+ `H_(2)O_(2)`. X combines readily with Y and `H_(2)O` to form crystals of Mohrs salt. X can be made in laboratory from Kipp's waste is heated in the presence of `O_(2)` and water, Z is also produced along with X. the reaction of X with `KMnO_(4)` in the presence of `H_(2)SO_(4)` also gives Z. Identify the correct match.

Options

A. `X=FeSO_(4)`
B. `X=Fe_(2)(SO_(4))_(3)`
C. `Y=(NH_(4))_(2)SO_(4)`
D. `Z=FeSO_(4)`

Explanation

To solve the question, we need to identify the compounds X, Y, and Z based on the clues provided in the question.

### Step-by-Step Solution:

1. **Identify Fenton's Reagent**:
- The question states that Fenton's reagent is X + H₂O₂.
- Fenton's reagent is commonly known to be ferrous sulfate (FeSO₄) combined with hydrogen peroxide (H₂O₂).
- Therefore, we can conclude that **X = FeSO₄**.

**Hint**: Recall that Fenton's reagent is used in oxidation reactions and is typically made from ferrous sulfate.

2. **Determine Y**:
- The question mentions that X (FeSO₄) combines readily with Y and water to form crystals of Mohr's salt.
- Mohr's salt is known to be (NH₄)₂SO₄·FeSO₄·6H₂O, which indicates that Y must be ammonium sulfate (NH₄)₂SO₄.
- Thus, we conclude that **Y = (NH₄)₂SO₄**.

**Hint**: Mohr's salt is a double salt that contains both ammonium sulfate and ferrous sulfate.

3. **Identify Z**:
- The question states that X can be made in the laboratory from Kipp's waste when heated in the presence of O₂ and water, producing Z along with X.
- Kipp's waste typically contains iron pyrite (FeS₂). When heated with O₂ and water, it produces FeSO₄ (X) and iron(III) sulfate (Fe₂(SO₄)₃).
- Therefore, Z is identified as **Z = Fe₂(SO₄)₃**.

**Hint**: The reaction of iron pyrite with oxygen and water leads to the formation of iron sulfate compounds.

4. **Reaction with KMnO₄**:
- The question also mentions that the reaction of X (FeSO₄) with KMnO₄ in the presence of H₂SO₄ gives Z.
- The balanced reaction shows that FeSO₄ reacts with KMnO₄ to produce Fe₂(SO₄)₃ (Z) along with other products.
- This confirms our identification of Z as **Z = Fe₂(SO₄)₃**.

**Hint**: KMnO₄ is a strong oxidizing agent and can oxidize ferrous ions to ferric ions.

### Final Identification:
- **X = FeSO₄**
- **Y = (NH₄)₂SO₄**
- **Z = Fe₂(SO₄)₃**

Thus, the correct matches are:
- X is equal to FeSO₄
- Y is equal to (NH₄)₂SO₄
- Z is equal to Fe₂(SO₄)₃
