What is the complete ionic equation for magnesium chloride and sodium carbonate?

The complete ionic equation for the reaction between magnesium chloride (MgCl₂) and sodium carbonate (Na₂CO₃) can be written as follows:

[ \text{Mg}^{2+} + 2\text{Cl}^- + 2\text{Na}^+ + \text{CO}_3^{2-} \rightarrow \text{MgCO}_3 (s) + 2\text{Na}^+ + 2\text{Cl}^- ]

In this reaction, magnesium ions (Mg²⁺) combine with carbonate ions (CO₃²⁻) to form solid magnesium carbonate (MgCO₃), while sodium (Na⁺) and chloride ions (Cl⁻) remain as spectator ions in solution.
