Answer:
The total ionic equation is:
2NH₄⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + CO₃⁻²(aq) → (NH₄)₂CO₃ (s) + 2Na⁺ (aq) + 2Cl⁻(aq)
The net ionic equation is: 2NH₄⁺(aq) + CO₃⁻²(aq) → (NH₄)₂CO₃ (s)
Explanation:
To determine the net ionic equation and the total ionic equation we may know that a change of state is produced in this reaction.
The reactants are: NH₄Cl and Na₂CO₃
We dissociate them:
NH₄Cl (aq) → NH₄⁺(aq) + Cl⁻(aq)
Na₂CO₃(aq) → 2Na⁺(aq) + CO₃⁻²(aq)
The ammonium carbonate is a solid salt, while the sodium chloride is a soluble one. So we have produced a solid, that's why there is a chagen of state.
The total ionic equation is:
2NH₄⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + CO₃⁻²(aq) → (NH₄)₂CO₃ (s) + 2Na⁺(aq) + Cl⁻(aq)
The ions that are repeated must be removed from the equation (they are called spectators ions, because they do not participate in the reaction)
The net ionic equation is: 2NH₄⁺(aq) + CO₃⁻²(aq) → (NH₄)₂CO₃ (s)
