Question
**Chemical Reaction Problem**

Referring to the reaction equation:

\[ 2 \text{KMnO}_4 + 16 \text{HCl} \rightarrow 5 \text{Cl}_2 + 2 \text{KCl} + 2 \text{MnCl}_2 + 8 \text{H}_2\text{O} \]

**a. Limiting Reactant Determination**

Given:  
- 47.0 g of KMnO₄  
- 55.0 g of HCl  

Determine which reactant is the limiting reactant for the production of Cl₂. Show your calculation with units and the correct number of significant figures.
