A) AgNO3(aq)+NaCl(aq)→AgCl(s)+NaNO3(aq)AgNO_3 (aq) + NaCl (aq) rightarrow AgCl (s) + NaNO_3 (aq) B) Ag+(aq)+Cl−(aq)→AgCl(s)Ag^+ (aq) + Cl^- (aq) rightarrow AgCl (s) C) Ag+(aq)+Na+(aq)+Cl−(aq)→AgCl(s)+Na+(aq)Ag^+ (aq) + Na^+ (aq) + Cl^- (aq) rightarrow AgCl (s) + Na^+ (aq) D) Ag+(aq)+NO3−(aq)+Na+(aq)+Cl−(aq)→AgCl(s)+NaNO3(aq)Ag^+ (aq) + NO_3^- (aq) + Na^+ (aq) + Cl^- (aq) rightarrow AgCl (s) + NaNO_3 (aq)
