Question
**Calculate the Heat of Reaction (ΔH) for the Following Reaction:**

\[2 \text{HCl}(g) + \text{Br}_2(g) \rightarrow 2 \text{HBr}(g) + \text{Cl}_2(g)\]

To perform this calculation, you will need to use bond energy values, which can be found by accessing the **Data** button on the ALEKS toolbar.

**Instructions:**
1. Look up the bond energies using the **Data** button.
2. Calculate the total bond energy of the reactants.
3. Calculate the total bond energy of the products.
4. Use the formula: 

\[\Delta H = \sum \text{Bond energies of reactants} - \sum \text{Bond energies of products}\]

5. Round your answer to the nearest kJ/mol.

**Answer Format:**

\[ \text{kJ/mol} \]

**Input Box:**
- A rectangular input box where the rounded value of ΔH in kJ/mol should be entered.

**Additional Tools:**
- **Check Button (X):** To verify or reset your answer.
- **Refresh Button (↻):** To restart the calculation process.
- **Help Button (?):** For additional assistance or hints.

**Explanation of Symbols and Tools:**
- The **X Button** might be used to cancel or clear the input.
- The **Refresh Button** is typically used to reset the calculation process to its initial state.
- The **Help Button** provides additional information or guidance on how to proceed with the calculation.

Make sure to follow the steps correctly to determine the heat of reaction accurately.
