Final answer:
AgNO3, known as silver nitrate, is made up of silver, nitrogen, and oxygen atoms. It dissociates into Ag+ and NO3- ions when dissolved in water.
Step-by-step explanation:
The formula AgNO_3 represents a compound made of silver (Ag), nitrogen (N), and oxygen (O) atoms. This is an ionic compound, typically known as silver nitrate, where the silver ion (Ag+) is bonded to the nitrate ion (NO3-). In the provided chemical reaction, silver nitrate
reacts with calcium chloride (CaCl2) to form silver chloride (AgCl) and calcium nitrate (Ca(NO3)2). When silver nitrate dissolves in water, it dissociates into silver ions (Ag+) and nitrate ions (NO3-), which are then uniformly dispersed in the aqueous solution. In solid form, AgCl does not dissociate into ions.
