Answer: The spectator ions are [tex]NO_3^-\text{ and }Na^+[/tex]
Explanation:
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:
[tex]Na_2CO_3+2HNO_3\rightarrow 2NaNO_3+H_2O+CO_2[/tex]
The ionic equation for the above reaction follows:
[tex]2Na^+(aq.)+CO_3^{2-}(aq.)+2H^+(aq.)+2NO_3^-\rightarrow 2Na^+(aq.)+2NO_3^-(aq.)+CO_2(g)+H_2O(l)[/tex]
The net ionic equation follows:
[tex]CO_3^{2-}(aq.)+2H^+(aq.)+\rightarrow CO_2(g)+H_2O(l)[/tex]
The ions which are present on both the sides of the equation are sodium and nitrate ions.
Hence, the correct answer are [tex]NO_3^-\text{ and }Na^+[/tex]
