### Completing a Balanced Molecular Chemical Equation

**Question:**
Complete the balanced molecular chemical equation for the reaction below. If no reaction occurs, write NR after the reaction arrow.

**Chemical Equation:**

\[ \text{Pb(NO}_3\text{)_2(aq) + KI(aq)} \rightarrow \]

**Instructions:**
- Use the provided digital keypad to enter the correct balanced equation. The keypad includes digits, ions, and chemical symbols.
- If no reaction occurs, use "NR" to indicate this.
- Confirm your answer by checking the balance of atoms and charge conservation.

#### Keypad Explanation:
- Numbers from 0 to 9 for balancing equations.
- Symbols for common ions such as \( \text{NO}_3^- \), \( \text{OH}^- \), \( \text{SO}_4^{2-} \), etc.
- Chemical elements like Pb, K, I, and other necessary symbols are available.
- Additional options include Reset and Delete to modify your response.
- Option to indicate a non-reaction with "NR".

#### Example:
For the reaction between lead(II) nitrate and potassium iodide in aqueous solution, mixing these will typically result in a double displacement reaction forming lead(II) iodide and potassium nitrate:

\[ \text{Pb(NO}_3\text{)_2(aq) + 2KI(aq)} \rightarrow \text{PbI}_2\text{(s) + 2KNO}_3\text{(aq)} \]

Balance both the number of atoms of each element and the charges on both sides of the equation.
