Question

Write balanced equation for A, B, C, D, E.

\[\ce{ZnS →[A]SO2 →[B]SO3→[C]H2S2O7 →[D]H2SO4 →[E]}\]

Answer 1

A: \[\ce{2ZnS + 3O2 -> 2ZnO + 2SO2}\]

B: \[\ce{2SO2 + O2 ⇌[V2SO5][450°C]2SO3}\]

C: \[\ce{SO3 + H2SO4 ⟶ H2S2O7}\]

D: \[\ce{H2S2O7 + H2O ⟶ 2H2SO4}\]

E: \[\ce{Zn + H2SO4 ⟶ ZnSO4 + H2 ↑}\]
