Answer:
i) The products obtained are- Carbon and Magnesium Oxide.
ii) The products obtained are- Sulfur and Magnesium Oxide.
Explanation:
(i) The reaction of magnesium with carbon dioxide is redox. Magnesium is oxidized and carbon is reduced. It is highly exothermic. After the reaction is over, we obtain carbon in granules and white magnesium oxide.
[tex]2Mg + CO_{2}[/tex] → [tex]2MgO + C+[/tex]Δ
(ii) The reaction of magnesium with sulfur dioxide is redox. Magnesium gets oxidized and sulfur gets reduced. It is also very exothermic. After the reaction is over, magnesium oxide and sulfur are obtained.
[tex]2Mg + SO_{2}[/tex] → [tex]2MgO+S+[/tex]Δ
