Mixing sodium bromide (NaBr) and silver acetate (AgC₂H₃O₂) will result in a double displacement reaction and the formation of:

* Silver bromide (AgBr), a pale yellow precipitate that is insoluble in water.

* Sodium acetate (NaC₂H₃O₂), which remains dissolved in the solution.

Here's the balanced chemical equation:

NaBr (aq) + AgC₂H₃O₂ (aq) → AgBr (s) + NaC₂H₃O₂ (aq)

The reaction is driven by the formation of the insoluble silver bromide precipitate. This is a common example of a precipitation reaction, where two soluble salts react to form an insoluble product.
