The correct Answer is:
To analyze the reaction \( \text{Mg} + \text{Cl}_2 \rightarrow \text{MgCl}_2 \), we need to determine the oxidation states of the elements involved and identify which species is oxidized and which is reduced. ### Step-by-Step Solution: 1. **Identify the Reactants and Products**: - Reactants: Magnesium (Mg) and Chlorine gas (\( \text{Cl}_2 \)) - Product: Magnesium chloride (\( \text{MgCl}_2 \)) 2. **Determine the Oxidation States**: - In elemental form, magnesium (\( \text{Mg} \)) has an oxidation state of 0. - In \( \text{MgCl}_2 \), magnesium has an oxidation state of +2. - Chlorine in \( \text{Cl}_2 \) also has an oxidation state of 0. - In \( \text{MgCl}_2 \), each chlorine atom has an oxidation state of -1. 3. **Identify Changes in Oxidation States**: - Magnesium changes from 0 (in \( \text{Mg} \)) to +2 (in \( \text{MgCl}_2 \)), indicating it is oxidized. - Chlorine changes from 0 (in \( \text{Cl}_2 \)) to -1 (in \( \text{MgCl}_2 \)), indicating it is reduced. 4. **Determine Electron Transfer**: - Magnesium loses 2 electrons to go from 0 to +2. - Each chlorine atom gains 1 electron to go from 0 to -1. Since there are 2 chlorine atoms, they collectively gain 2 electrons. 5. **Conclusion**: - Since magnesium is losing electrons, it is the reducing agent (it is oxidized). - Since chlorine is gaining electrons, it is the oxidizing agent (it is reduced). ### Final Answer: - Magnesium (Mg) is oxidized, and chlorine (\( \text{Cl}_2 \)) is reduced in the reaction \( \text{Mg} + \text{Cl}_2 \rightarrow \text{MgCl}_2 \). ---
