D. `N_(2)O_(5)` and `H_(2)O`

Answer

To solve the question "HNO₃ in aqueous solution yields," we can break it down into the following steps:

### Step 1: Understand the Dissociation of HNO₃
When nitric acid (HNO₃) is dissolved in water, it dissociates into its constituent ions. This is a key property of strong acids, which fully ionize in solution.

**Hint:** Recall that strong acids like HNO₃ completely dissociate in water.

### Step 2: Write the Dissociation Equation
The dissociation of HNO₃ in water can be represented by the following chemical equation:
\[ \text{HNO}_3 (aq) \rightarrow \text{H}^+ (aq) + \text{NO}_3^- (aq) \]

**Hint:** Remember that HNO₃ produces hydrogen ions (H⁺) and nitrate ions (NO₃⁻) when it dissociates.

### Step 3: Consider the Role of Water
In the aqueous solution, water acts as a solvent and facilitates the ionization of HNO₃. The H⁺ ions can interact with water molecules to form hydronium ions (H₃O⁺).

**Hint:** Think about how H⁺ ions interact with water to form H₃O⁺.

### Step 4: Write the Complete Ionization Reaction
Taking into account the formation of hydronium ions, we can express the complete ionization of HNO₃ in water as:
\[ \text{HNO}_3 (aq) + \text{H}_2\text{O} (l) \rightarrow \text{H}_3\text{O}^+ (aq) + \text{NO}_3^- (aq) \]

**Hint:** Remember to include water in the equation to show how H⁺ ions are stabilized in solution.

### Step 5: Conclusion
Thus, the products of HNO₃ in aqueous solution are hydronium ions (H₃O⁺) and nitrate ions (NO₃⁻).

**Final Answer:** HNO₃ in aqueous solution yields H₃O⁺ and NO₃⁻.
