To calculate the standard enthalpy of formation (ΔH_f^(@)) for the chloride ion (Cl^(-)), we can use the given reactions and their enthalpy changes. Let's break down the steps: ### Step 1: Write down the given reactions and their enthalpy changes. 1. Reaction 1: \[ \frac{1}{2} H_2(g) + \frac{1}{2} Cl_2(g) \rightarrow HCl(g), \quad \Delta H_f^(@) = -92.4 \, \text{kJ} \] ...
