Answer

To solve the given question, we need to analyze the reaction between phosphine (PH₃) and nitric acid (HNO₃) and identify the products formed, which are X (an oxyacid of phosphorus) and Y (an oxide of nitrogen).

### Step-by-Step Solution:

1. **Identify the Reactants**:
The reactants in the reaction are phosphine (PH₃) and nitric acid (HNO₃).

2. **Understand the Reaction**:
When phosphine reacts with nitric acid, it typically leads to the formation of an oxyacid of phosphorus and nitrogen oxides.

3. **Determine the Products**:
- The oxyacid of phosphorus formed in this reaction is phosphoric acid (H₃PO₄).
- The oxide of nitrogen produced is nitrogen dioxide (NO₂).

4. **Write the Balanced Reaction**:
The balanced chemical equation for the reaction can be represented as:
\[ 3 PH_3 + 8 HNO_3 \rightarrow H_3PO_4 + 6 NO_2 + 4 H_2O \]
This shows that phosphine reacts with nitric acid to produce phosphoric acid, nitrogen dioxide, and water.

5. **Identify X and Y**:
- From the balanced equation, we can see that:
- X (the oxyacid of phosphorus) is H₃PO₄.
- Y (the oxide of nitrogen) is NO₂.

6. **Conclusion**:
Therefore, the correct statements regarding the products are:
- X is H₃PO₄ (phosphoric acid).
- Y is NO₂ (nitrogen dioxide).

### Final Answer:
The correct statements are:
- X is H₃PO₄.
- Y is NO₂.
