Can you help me with c please?
**Estimating Enthalpy of Reactions Using Bond Enthalpies** This section outlines the calculation of approximate enthalpy changes (in kJ) for specific chemical reactions using average bond enthalpies. It is essential to have an understanding of what bond enthalpies signify and how they can be used to estimate the energy changes during chemical reactions. **Reactions to Analyze:** (a) \( \text{Cl}_2(g) + 3 \text{F}_2(g) \rightarrow 2 \text{ClF}_3(g) \) - The calculated enthalpy change is \(-823 \, \text{kJ} \). (b) \( \text{H}_2\text{C=CH}_2(g) + \text{H}_2(g) \rightarrow \text{H}_3\text{CCH}_3(g) \) - The calculated enthalpy change is \(-127 \, \text{kJ} \). (c) \( 2 \text{CH}_3(\text{C=O})\text{H}(g) + 5 \text{O}_2(g) \rightarrow 4 \text{CO}_2(g) + 4 \text{H}_2\text{O}(g) \) - The box is left empty, indicating that this calculation needs to be performed. **Supporting and Additional Educational Resources:** - **Supporting Materials:** - Periodic Table - Constants and Factors - Supplemental Data - **Additional Materials:** - Section 7.5 These resources are linked within the educational platform for further reference and a deeper understanding of the chemical principles involved. **Actionable Features on the Platform:** - **Check Score**: Allows users to verify the calculated scores. - **Hide Answer**: Gives the option to conceal the answers for independent problem-solving. - **Hide Solution**: Allows users to attempt the solution without immediate access to the full explanation. - **Try Another**: Provides an option to explore additional similar problems for practice. This interactive educational platform encourages engagement through problem-solving and immediate feedback, which are crucial for learning and understanding chemical reaction enthalpies.
