Answer: \(\Zn^{2+}+2S^{2-}rightarrow ZnS\)
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:
\(Zn(NO_3)_2(aq)+K_2S(aq)\rightarrow ZnS(s)+2KNO_3(aq)\)
The ions which are present on both the sides of the equation are potassium and nitrate ions and hence are not involved in net ionic equation.
\(Zn^{2+}+2NO_3^-+2K^++S^{2-}\rightarrow ZnS+2K^++NO_3^-\)
Hence, the net ionic equation is \(\Zn^{2+}+2S^{2-}rightarrow ZnS\)
