### Educational Content: Chemical Reaction Analysis

**Question:**
How many moles of nitrogen gas would be produced if 3.40 moles of copper(II) oxide were reacted with excess ammonia in the following chemical reaction?

**Chemical Reaction Equation:**
\[ 2 \text{NH}_3(g) + 3 \text{CuO} (s) \rightarrow 3 \text{Cu}(s) + \text{N}_2(g) + 3 \text{H}_2\text{O}(g) \]

### Explanation:
This is a stoichiometry problem that involves determining the amount of product (nitrogen gas) formed from a given amount of reactant (copper(II) oxide).

#### Steps to solve:
1. **Identify the stoichiometric ratio** from the balanced chemical equation:
   - 3 moles of CuO produce 1 mole of N₂.

2. **Calculate the moles of N₂ produced:**
   - If you start with 3.40 moles of CuO, use the ratio to find the moles of N₂ produced:

   \[
   \left(\frac{1 \text{ mole of N}_2}{3 \text{ moles of CuO}}\right) \times 3.40 \text{ moles of CuO} = 1.13 \text{ moles of N}_2
   \]

### Interactive Element:
Below the question, there's a calculator interface that users can use to input their calculated result:
- **Input Options:** 
  - **Number buttons (0-9):** For entering numerical values.
  - **Decimal (.):** For precise calculations.
  - **Delete (C) and Backspace (\(\times\)):** For correcting mistakes.
  - **Multiplier (x10) box:** For scientific notation (not needed for this calculation).
