* Sodium (Na) is a more reactive metal than iron (Fe). This means it has a stronger tendency to lose electrons and form positive ions.

* Iron oxide (Fe₂O₃) is a compound where iron is in a positive oxidation state.

* The reaction involves sodium displacing iron from its oxide. The sodium atoms lose electrons to form Na⁺ ions, and the iron ions (Fe³⁺) in the oxide gain electrons to become elemental iron (Fe).

Here's the chemical equation:

3Na + Fe₂O₃ → 2Fe + 3Na₂O

Breakdown:

* Reactants: Sodium (Na) and Iron oxide (Fe₂O₃)

* Products: Iron (Fe) and Sodium oxide (Na₂O)

Important Notes:

* This reaction is highly exothermic (releases a lot of heat) and can be quite vigorous.

* The reaction is often used in the production of iron from iron ore.

* You should never attempt this reaction without proper safety precautions and knowledge of handling reactive metals.
