To write the molecular equation for the combination of aqueous solutions of sodium chloride (NaCl) and silver nitrate (AgNO3), you need to know the chemical formulas of these compounds and the balanced chemical equation for the reaction.
The balanced chemical equation for this reaction is:
AgNO3 (aq) + NaCl (aq) -> AgCl (s) + NaNO3 (aq)
This equation shows that silver nitrate reacts with sodium chloride to form silver chloride (which is a solid precipitate) and sodium nitrate.
The molecular equation for the reaction is:
AgNO3 (aq) + NaCl (aq) -> AgCl (s) + NaNO3 (aq)
In this equation, (aq) represents the compounds dissolved in water ("aqueous solutions") and (s) represents a solid precipitate. The sum of all coefficients in this equation is:
1 + 1 + 1 + 1 = 4
