Text Solution

AI Generated Solution

To solve the problem of 71g of chlorine gas expanding freely into a vacuum, we will calculate the work done (w), heat exchanged (q), change in internal energy (ΔU), and change in enthalpy (ΔH). ### Step-by-step Solution: 1. **Identify the Conditions:** - Given: 71 g of chlorine gas (Cl₂). - The gas expands freely into a vacuum, meaning there is no external pressure acting on it. ...
