Let’s carry out a chain of transformations of inorganic substances.
2ZnS + 3O2 = 2ZnO + 2SO2 (zinc sulfide roasting reaction)
2SO2 + O2 = 2SO3 (the reaction proceeds in the presence of a catalyst)
SO3 + H2O = H2SO4
S + H2 = H2S
2H2S + 3O2 = 2SO2 + 2H20
2SO2 + O2 = 2SO3
SO3 + H2O = H2SO4 (industrial method for producing sulfuric acid)
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.
