1) H2S + O3 = SO2 + H2O (when hydrogen sulfide interacts with ozone, sulfur (IV) oxide and water are formed);
2) SO2 + 2NaOH = Na2SO3 + H2O (when sulfur (IV) oxide interacts with sodium hydroxide, sodium sulfite and water are formed);
3) Na2SO3 + CuSO4 = Na2SO4 + CuSO3 (when sodium sulfite interacts with copper sulfate, copper sulfite and sodium sulfate 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.
