Write down the reaction equation: Zn → zns → h2s → s → so2 → so3 → h2so4 → baso4

1. Impact of shock waves on a mixture of sulfur and zinc powders.
2Zn + S2 = 2ZnS.
2. Diluted sulfuric acid with sulphide with the release of hydrogen sulphide.
ZnS + 2HCl = ZnCl2 + H2S.
3. Combustion of hydrogen sulfide in a lack of oxygen.
2H2S + O2 = 2S + 2H2O.
4. Combustion of sulfur with the release of sulfur dioxide.
S + O2 = SO2.
5. Oxidation to trioxide.
2SO2 + O2 = 2SO3.
6. Formation of sulfuric acid.
SO3 + H2O = H2SO4.
7. The reaction of acid exchange with barium salt.
H2SO4 + BaCl2 = BaSO4 + 2HCl.
