Vedclass · Answer

(C) When magnesium wire is heated in an atmosphere of $CO_2$,it continues to burn because magnesium is a strong reducing agent. It reduces $CO_2$ to carbon and itself gets oxidised to magnesium oxide $(MgO)$. The chemical reaction is: $2Mg + CO_2 \rightarrow 2MgO + C$. Therefore,magnesium acts as a reducing agent and removes oxygen from $CO_2$.

Magnesium wire is heated in the atmosphere of $CO_2$ because
