Consider the total ionic equation below.

Upper B a superscript 2 plus, plus 2 upper N upper O subscript 3 superscript minus, plus 2 upper N a superscript plus, plus upper C upper O subscript 3 superscript 2 minus right arrow upper Ba upper C Upper O subscript 3 plus 2 upper N a superscript plus, plus 2 upper N upper O subscript 3 superscript minus.

Which is the net ionic equation for the reaction?

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!!!

we need the questions , i may then you.
