Urgent plzz help meeee thx I HAVE EXAMEEE

Answer 1

Answer: $2Ag^{+}(aq)+CO_3^{2-}(aq)\rightarrow Ag_2CO_3(s)$

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:

$2AgF(aq)+Na_2CO_3(aq)\rightarrow Ag_2CO_3(s)+2NaF(aq)$

The complete ionic equation is;  

$2Ag^{+}(aq)+2F^-(aq)+2Na^+(aq)+CO_3^{2-}(aq)\rightarrow Ag_2CO_3(s)+2Na^+(aq)+2F^-(aq)$

The ions which are present on both the sides of the equation are $Na^+$ and $F^-$ and are not involved in net ionic equation.

Hence, the net ionic equation is :

$2Ag^{+}(aq)+CO_3^{2-}(aq)\rightarrow Ag_2CO_3(s)$
