Yes, sodium carbonate (Na₂CO₃) will react with copper(II) nitrate (Cu(NO₃)₂) in an aqueous solution. This is a double displacement reaction where the cations and anions of the reactants switch partners.

Here's the balanced chemical equation:

Na₂CO₃(aq) + Cu(NO₃)₂(aq) → CuCO₃(s) + 2NaNO₃(aq)

Here's what happens:

* Sodium carbonate (Na₂CO₃) is a soluble ionic compound that dissociates in water to form sodium ions (Na⁺) and carbonate ions (CO₃²⁻).

* Copper(II) nitrate (Cu(NO₃)₂) is also soluble and dissociates into copper(II) ions (Cu²⁺) and nitrate ions (NO₃⁻).

* When these solutions are mixed, the copper(II) ions (Cu²⁺) and carbonate ions (CO₃²⁻) combine to form copper(II) carbonate (CuCO₃), which is insoluble in water and precipitates out as a solid.

* The remaining ions, sodium (Na⁺) and nitrate (NO₃⁻), remain in solution as sodium nitrate (NaNO₃), which is soluble.

Evidence of the Reaction:

* You will observe the formation of a blue-green precipitate (copper(II) carbonate) when the two solutions are mixed.

* The reaction is also exothermic, meaning it releases heat and the solution will feel slightly warm.
