Question

ZnS-H2S-SO2-FeS2-H2SO4

Answer 1

3 ZnS + 2 H3AsO4 = Zn3(AsO4)2 ↓ + 3 H2S ↑
2 H2S + 3 O2 = 2 H2O + 2 SO2 ↑

Answer 2

This is a chemical reaction involving multiple compounds and elements. It could be described as the reaction between zinc sulfide (ZnS), hydrogen sulfide (H2S), sulfur dioxide (SO2), iron pyrite (FeS2), and sulfuric acid (H2SO4). The specific reaction that occurs would depend on the specific conditions and concentrations of the compounds present. However, one possible reaction that could occur is:

ZnS + 2H2SO4 → ZnSO4 + 2H2S

FeS2 + 7O2 → Fe2O3 + 4SO2

2H2S + SO2 → 3S + 2H2O

Overall equation:

ZnS + 2FeS2 + 7O2 + 2H2SO4 → ZnSO4 + 2Fe2O3 + 6S + 4H2O
