Answer:
Zero grams of NaCl & KNO₃ ... The reagents mixed in aqueous solution would not produce products as no driving force is present; i.e., no precipitate, weak electrolyte or gas decomposition product will form.
Explanation:
NaNO₃(aq) + KCl(aq) => (theoritically) NaCl(aq) + KNO₃(aq)
However all chloride salts from metathesis rxns remain soluble and 100% ionized except for halide derivatives of Hg⁺², Ag⁺ & Pb⁺₂. Further, all NO₃⁻ salt derivatives also remain soluble and 100% ionized.
Technically, metathesis reactions (also known as double replacement rxns) depend upon the formation of a 'driving force' that leaves the reaction system in the form of a precipitate, weak electrolyte (weak acid or weak base) or a gas decomposition product. So, the reaction in this case should be as follows:
NaNO₃(aq) + KCl(aq) => No Reaction
