Final answer:
The correct net ionic equation for the reaction between AgNO₃(aq) and 2NaCl(aq) is Ag⁺(aq) + Cl⁻(aq) → AgCl(s), which shows the formation of solid silver chloride.
Step-by-step explanation:
The net ionic equation for AgNO₃(aq) + 2NaCl (aq) = Na₂NO₃ + AgCl represents only the ions and compounds that are directly involved in the chemical reaction, which is the formation of the insoluble silver chloride (AgCl) precipitate. When writing the net ionic equation, we omit the spectator ions such as Na⁺ and NO₃⁻, which appear unchanged on both sides of the equation.
Therefore, the correct net ionic equation for this reaction is:
Ag⁺ (aq) + Cl⁻ (aq) → AgCl(s)
This highlights that the positively-charged silver ion (Ag⁺) reacts with the negatively-charged chloride ion (Cl⁻) to form solid silver chloride.
