Carry out a chain of chemical transformations S-ZnS-SO2 – SO3-H2SO4-BaSO4
| January 12, 2021 | education
S → ZnS → SO2 → SO3 → H2SO4 → BaSO4:
We get the following equations:
1) S + Zn → ZnS ↓;
2) 2ZnS + 3O2 → 2ZnO + 2SO2 ↑;
3) 2SO2 + O2 → 2SO3 ↑ (in the presence of a V2O5 catalyst);
4) SO3 ↑ + H2O → H2SO4;
5) H2SO4 + BaCl2 → BaSO4 ↓ + 2HCl (qualitative reaction for H2SO4).
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.
