Write the reaction equations: 1) Sulfuric acid- Copper sulfate 2- Barium sulfate 2) Zinc sulfide- Sulfur dioxide- Sodium sulfite- Lead sulfite 2

1 chain:

1) H2SO4 + CuO = CuSO4 + H2O (when sulfuric acid interacts with copper oxide, copper (II) sulfate and water are formed);

2) CuSO4 + BaCl2 = BaSO4 + CuCl2 (when copper (II) sulfate interacts with barium chloride, barium sulfate and copper chloride are formed).

2 chain:

1) 2ZnS + 3O2 = 2ZnO + 2SO2 (when zinc sulfide interacts with oxygen, zinc oxide and sulfur dioxide are formed);

2) SO2 + 2NaOH = Na2SO3 + H2O (when sulfur dioxide reacts with sodium hydroxide, sodium sulfite and water are formed);

3) Na2SO3 + Pb (NO3) 2 = 2NaNO3 + PbSO3 (when sodium sulfite reacts with lead nitrate, sodium nitrate and lead (II) sulfite are formed).



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.
