Answer

$K_{c} = \frac{[Ag+]^2}{[Zn^+2]}$ heterogeneous

Work Step by Step

The expression for Kc is the concentration of products raised to their respective stoichiometric coefficients divided by the concentration of the reactants raised to their stoichiometric coefficients. $K_{c} = \frac{[Ag+]^2}{[Zn^+2]}$ Here the Zn and the Ag are omitted since they are solids and you cannot have concentration of a pure solid. Since we have reactants in solid and aqueous phases, it is heterogeneous
