Question
**Question:** Given the following reactions, what is the enthalpy change for the reaction \(3D \rightarrow A + 3B + 5C\) in kJ? 1. \( A \rightarrow 3B + C, \Delta H = 100 \, \text{kJ} \) 2. \( A + C \rightarrow D + B, \Delta H = -200 \, \text{kJ} \) **Explanation:** The problem asks us to determine the enthalpy change for the reaction provided using the given information about two separate reactions and their enthalpy changes. To solve this problem, we will likely need to manipulate and combine these reactions according to Hess's Law to find the overall enthalpy change for the target reaction \(3D \rightarrow A + 3B + 5C\).
