See answer below.

Work Step by Step

a) $AgNO_3(aq)+Cl^-\rightarrow AgCl(s)+NO_3^-(aq)$ b) $2\ AgNO_3(aq)+K_2CrO_4(aq)\rightarrow Ag_2CrO_4(s)+2\ KNO_3(aq)$ Net ionic: $2\ Ag^+(aq)+CrO_4^{2-}(aq)\rightarrow Ag_2CrO_4(s)$ c) $25.60\ mL\times 0.001036\ M=0.02652\ mmol$ of silver nitrate, from stoichiometry that's the same as chloride: $0.02652\ mmol\times 35.45\ mg/mmol=0.9402\ mg$ of chloride. $0.9402\ mg/0.0500\ L=18.80\ mg/L$ of chloride, which is sufficient to promote oyster growth.
