Write the reaction equations: silver sulfide (1) -silver-silver nitrate-silver-silver chloride-silver

Let’s write down the solution:
Ag2S + 4HNO3 = 2AgNO3 + 2NO2 + S + 2H2O – ОВР;
AgNO3 + HCl = AgCl + HNO3 – ion exchange;
AgCl = Ag + + Cl-;
K- | Ag + + e = Ag | 2 – recovery;
A + | 2Cl- – 2e = Cl2 | 1 – oxidation;
2AgCl = 2Ag + Cl2 – silver was obtained during electrolysis.
Silver salts are of practical importance, for example, silver nitrate is used in medicine as a lapis for sterilization and in photography as a developer. The reaction equations show the relationship between simple substances of metals and their salts.
