Answer:
The net ionic equation is
Ba²⁺ + CO₃²⁻ → BaCO₃(s)
Explanation:
The chemical reaction described is given as
Ba²⁺ + 2NO₃⁻ + 2Na⁺ + CO₃²⁻ → BaCO₃(s) + 2Na⁺ + 2NO₃⁻
The net ionic equation is obtained by eliminating the ions that appear on both sides of the equation.
And those ions are 2Na⁺ and 2NO₃⁻.
This is a double displacement reaction in which BaNO₃ (aq) reacts with Na₂CO₃ (aq) to form BaCO₃ (s) and NaNO₃ (aq).
The aqueous solutions exist in ionic forms in the reaction and in the net ionic equation, ioms that appear on both sides of the overall equation obviously cancel out.
Hope this Helps!!!
