What information does a complete ionic equation give that the balanced equation doesn’t show?

For example, NaCl reacts with AgNO₃ to produce NaNO₃ and AgCl (a precipitate). The chemical equation for this reaction will be:

NaCl + AgNO₃ → NaNO₃ + AgCl (s)

The complete ionic equation for the same reaction will be:

Na⁺ + Cl⁻ + Ag⁺ + NO₃⁻ → Na⁺ + NO₃⁻ + AgCl (s)

Excepting for the AgCl solid, all other species in the ionic equation are written as ions.

Their subscripts show their charges. There's no subscript in the chemical equation. It takes some reasoning to tell the ions formed from each of the species.

i think that the answer is c

what is the question here. i think you messed up.
