Answer

To determine the products formed when nitric acid (HNO₃) reacts with phosphorus pentoxide (P₄O₁₀), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**:
- The reactants in this reaction are nitric acid (HNO₃) and phosphorus pentoxide (P₄O₁₀).

2. **Understand the Reaction**:
- When HNO₃ reacts with P₄O₁₀, it typically leads to the formation of phosphoric acids and nitrogen oxides.

3. **Write the Balanced Reaction**:
- The balanced chemical equation for the reaction is:
\[ 4 \text{HNO}_3 + \text{P}_4\text{O}_{10} \rightarrow 4 \text{HPO}_3 + 2 \text{N}_2\text{O}_5 \]
- This indicates that for every 4 moles of nitric acid, 1 mole of phosphorus pentoxide reacts to produce 4 moles of metaphosphoric acid (HPO₃) and 2 moles of dinitrogen pentoxide (N₂O₅).

4. **Identify the Products**:
- The products formed from this reaction are:
- Metaphosphoric acid (HPO₃)
- Dinitrogen pentoxide (N₂O₅)

5. **Conclusion**:
- Therefore, the products formed when HNO₃ reacts with P₄O₁₀ are HPO₃ and N₂O₅.

### Final Answer:
The products formed are HPO₃ (metaphosphoric acid) and N₂O₅ (dinitrogen pentoxide).
