Solution Stoichiometry

Q. To measure the amount of chlorine in a well-boring fluid, an analytical chemist adds 0.1200 M silver nitrate (AgNO3) solution to a 49.00 g sample of the fluid and collects the solid silver chloride (AgCl) product. When no more AgCl is produced, she filters, washed and weighs it, and finds that 1.03 g has been produced. The balanced chemical equation for the reaction is: Cl-(aq) + AgNO3(aq) → AgCl(s) + NO3-(aq) What kind of reaction is this?
