### Stoichiometry Question

**Question:**
When 4 moles of aluminum are allowed to react with an excess of chlorine gas, \( \text{Cl}_2 \), how many moles of aluminum chloride are produced?

**Chemical Reaction Equation:**
\[ 2\text{Al} + 3\text{Cl}_2 \rightarrow 2\text{AlCl}_3 \]

**Answer Choices:**
- 2 moles
- 5 moles
- 4 moles
- 3 moles

**Correct Answer:**
- 4 moles

**Explanation:**
According to the balanced chemical equation \( 2\text{Al} + 3\text{Cl}_2 \rightarrow 2\text{AlCl}_3 \), 2 moles of aluminum react to form 2 moles of aluminum chloride. Therefore, if 4 moles of aluminum are present, they will produce 4 moles of aluminum chloride in the presence of excess chlorine gas.
