You're asking for the balanced equation for a reaction that doesn't actually occur. Here's why:

* Sodium is more reactive than iron. Sodium has a higher tendency to lose electrons and form positive ions. This means it will readily displace iron from its compounds.

The actual reaction:

Sodium reacts with iron(II) oxide (FeO) to produce sodium oxide (Na₂O) and iron.

Here's the balanced chemical equation:

2 Na + FeO → Na₂O + Fe

Explanation:

* 2 Na: Two sodium atoms are needed to balance the charge of the oxide ion (O²⁻) in sodium oxide.

* FeO: One molecule of iron(II) oxide.

* Na₂O: One molecule of sodium oxide.

* Fe: One atom of iron.
