Magnesium wire is heated in the atmosphere of CO2 because : — s Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Magnesium has a very strong affinity for oxygen and can burn even in a carbon dioxide (CO2) atmosphere. Step 2: When burning magnesium is introduced into a jar of CO2, it continues to burn, reducing CO2 to carbon and forming magnesium oxide: 2Mg + CO2 -> 2MgO + C. Step 3: In this reaction, magnesium acts as a powerful reducing agent by removing oxygen from CO2. This matches option (c).
