Question

When liquid silver nitrate and liquid sodium chloride are combined, solid silver chloride forms along with a new liquid, sodium nitrate. Which substance represents the precipitate?
A: silver nitrate
B: silver chloride
C: sodium chloride
D: sodium nitrate

Answer 1

Answer: B) silver chloride

Explanation: $AgNO_3(aq)+NaCl(aq)\rightarrow NaNO_3(aq)+AgCl(s)$

This is a chemical change and a double displacement reaction in which exchange of ions take place.

Precipitate is the chemical compound which is not soluble in solvent or water and thus remains in solid form. Here $AgCl$ is appearing in solid form and thus is a precipitate.

Answer 2

B Silver Chloride 
when you mix AgNO3- and NaCl- they make AgCl which is insoluble and settle to the bottom of the test tube, and NaNO3 which remains as a liquid solution
