The balanced reaction between potassium carbonate (K₂CO₃) and iron(II) bromide (FeBr₂) is:

K₂CO₃ (aq) + FeBr₂ (aq) → FeCO₃ (s) + 2 KBr (aq)

Here's the breakdown:

* Reactants:

* Potassium carbonate (K₂CO₃): A soluble ionic compound.

* Iron(II) bromide (FeBr₂): A soluble ionic compound.

* Products:

* Iron(II) carbonate (FeCO₃): An insoluble solid that precipitates out of solution.

* Potassium bromide (KBr): A soluble ionic compound that remains in solution.

Explanation of the balancing:

* Iron: One iron atom on each side of the equation.

* Carbon: One carbon atom on each side.

* Bromine: Two bromine atoms on each side.

* Potassium: Two potassium atoms on each side.

* Oxygen: Three oxygen atoms on each side.

This reaction is a double displacement reaction, where the cations and anions of the reactants switch partners. The formation of the insoluble iron(II) carbonate drives this reaction forward.
