(ii) X and Y are `CO_(2)` and `H_(2)O` respectively.
(iii) Z is `(NH_(4))_(2)CO_(3)`.
Identify the correct option.

Options

A. (i) and (ii)
B. only (iii)
C. (i) and (iii)
D. All statements are correct.

Explanation

To solve the given problem, we need to analyze the series of reactions and the statements provided. Let's break it down step by step.

### Step 1: Identify the Reaction
The reaction provided is:
\[ \text{NaCl} + X + Y + \text{NH}_3 \rightarrow \text{NaHCO}_3 + \text{NH}_4\text{Cl} \]
This is indicative of the Solvay process, which is used to produce sodium carbonate (washing soda).

### Step 2: Determine X and Y
In the Solvay process, the reactants include sodium chloride (NaCl), ammonia (NH₃), carbon dioxide (CO₂), and water (H₂O).

From the context:
- **X** is identified as **CO₂**.
- **Y** is identified as **H₂O**.

### Step 3: Analyze the Products
The products of the initial reaction are sodium bicarbonate (NaHCO₃) and ammonium chloride (NH₄Cl).

### Step 4: Further Reactions
The next part of the reaction sequence involves heating the sodium bicarbonate:
\[ \text{NaHCO}_3 \rightarrow \text{Z} + \text{H}_2\text{O} + \text{CO}_2 \]
Here, Z is formed after the decomposition of sodium bicarbonate, which is typically sodium carbonate (Na₂CO₃).

### Step 5: Identify Z
Thus, Z is:
\[ Z = \text{Na}_2\text{CO}_3 \]

### Step 6: Final Product
When sodium carbonate is hydrated, it can form sodium carbonate decahydrate (washing soda):
\[ \text{Na}_2\text{CO}_3 \cdot 10\text{H}_2\text{O} \]

### Conclusion
Now, let's evaluate the statements:
1. **This reaction is a Solvay's process.** - **True**
2. **X and Y are CO₂ and H₂O respectively.** - **True**
3. **Z is (NH₄)₂CO₃.** - **False** (Z is Na₂CO₃, not (NH₄)₂CO₃)

### Correct Option
The correct statements are (i) and (ii). Therefore, the correct option is the one that states both (i) and (ii) are true.
