You're asking about a chemical reaction! Here's how to break it down and get the ending:

The Reaction:

Sodium (Na) is a very reactive metal. Iron carbonate (FeCO₃) is a salt. When you mix them, you get a single displacement reaction. This means the sodium will try to replace the iron in the compound.

The Products:

* Sodium carbonate (Na₂CO₃): The sodium will combine with the carbonate ion (CO₃²⁻).

* Iron (Fe): The iron will be displaced and become elemental iron.

The Equation:

2Na + FeCO₃ → Na₂CO₃ + Fe

Important Note: This reaction is likely to be quite slow, especially at room temperature. You'd need to provide heat and potentially a little water to make it happen more readily.
