**Redox Reaction Analysis**

In the above redox reaction: 

\[2\text{Al}^{3+} + \text{Br}^- + 3\text{H}_2\text{O} \longrightarrow 2\text{Al} + \text{BrO}_3^- + 6\text{H}^+\]

Use oxidation numbers to identify the following:

- **Name of the element oxidized:**
  - [Blank space for answer]
  
- **Name of the element reduced:**
  - [Blank space for answer]

- **Formula of the oxidizing agent:**
  - [Blank space for answer]

- **Formula of the reducing agent:**
  - [Blank space for answer]

**Explanation:** 

This exercise requires the analysis of a redox (reduction-oxidation) reaction. By determining the changes in oxidation numbers of the elements, you can identify which element is oxidized (loses electrons and increases in oxidation number) and which is reduced (gains electrons and decreases in oxidation number). The oxidizing agent is the substance that is reduced, while the reducing agent is the substance that is oxidized.
