The following substances are given: iron (II) sulfate, iron (II) sulfide, ammonia, copper (II) nitrate, hydrochloric acid, silver nitrate, sulfuric acid. Write the equations of all possible reactions occurring in pairs between the proposed substances in aqueous solutions

The following reactions are allowed:
FeSO4 + 2NH3 * H2O = Fe (OH) 2+ (NH4) 2SO4
2FeSO4 + 2H2SO4 (c.) = Fe2 (SO4) 3 + SO2 + 2H2O
FeS + H2SO4 = FeSO4 + H2S
FeS + NH3 * H2O = Fe (OH) 2+ (NH4) 2S
FeS + 2HCl = FeCl2 + H2S
2NH3 * H2O + Cu (NO3) 2 = Cu (OH) 2 + 2NH4NO3
2NH3 * H2O + 2AgNO3 = Ag2O + H2O + 2NH4NO3
NH3 + НCl = NH4Cl
2NH3 + H2SO4 = (NH4) 2SO4
HCl + AgNO3 = AgCl + HNO3

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
