<u>Answer:</u> The net ionic equation is given below.
<u>Explanation:</u>
Net ionic equation of any reaction does not include any spectator ions.
These ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.
The chemical equation for the reaction of hydrochloric acid and potassium carbonate is given as:

Ionic form of the above equation follows:

As, potassium and chloride ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation.
The net ionic equation for the above reaction follows:

Hence, the net ionic equation is given above.
Answer:
i am sure its the last one
