1. **Question:** Based on the following reaction, what energy change occurs when 1.0 moles of chlorine react?
**Reaction:**
\[ \text{CH}_4(g) + 4 \text{Cl}_2(g) \rightarrow \text{CCl}_4(g) + 4 \text{HCl}(g) \]
**Enthalpy Change (\(\Delta H\)):**
\(\Delta H_{rxn} = -434 \, \text{kJ}\)
---
*Note:* The text highlights the calculation of energy changes in a chemical reaction involving methane (\( \text{CH}_4 \)) and chlorine (\( \text{Cl}_2 \)), producing carbon tetrachloride (\( \text{CCl}_4 \)) and hydrogen chloride (\( \text{HCl} \)). The reaction is exothermic, as indicated by the negative enthalpy change.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F85a2fef8-75c6-4f70-afce-e76c8de2cc0b%2F9b1201a4-4d1d-40b9-9a6c-340579d6e626%2F1s6k90i.jpeg&w=3840&q=75)
