How do you balance this equation: #AgNO_3 + NaCl -> AgCI + NaNO_3#?
Your equation is already balanced.
Silver chloride will precipitate from solution as a curdy white because of its exceptional insolubility in water. The other materials are along for the ride and will remain in water as the aquated ions,
We could write the business end of this equation, as the net ionic equation:
Note that as in all stoichiometrically balanced equations, (i) mass is conserved, and (ii) charge is conserved.
