Question

ZnS ---- > ZnO ---- > ZnSO4

Answer 1

ZnS → ZnO → ZnSO₄

1) 2ZnS + 3O₂ = 2ZnO + 2SO₂↑

2) ZnO + H₂SO₄ = ZnSO₄ + H₂O

Answer 2

It seems like you're describing a series of chemical reactions involving zinc sulfide (ZnS) converting into zinc oxide (ZnO) and then into zinc sulfate (ZnSO4). Let's break down these reactions step by step:

1. ZnS (Zinc Sulfide) to ZnO (Zinc Oxide): The conversion of zinc sulfide to zinc oxide typically involves the oxidation of ZnS. This can be achieved by heating ZnS in the presence of oxygen or air:

   2 ZnS + 3 O2 → 2 ZnO + 2 SO2

   In this reaction, zinc sulfide (ZnS) reacts with oxygen (O2) to form zinc oxide (ZnO) and sulfur dioxide (SO2) as a byproduct.

2. ZnO (Zinc Oxide) to ZnSO4 (Zinc Sulfate): To convert zinc oxide (ZnO) into zinc sulfate (ZnSO4), you typically need to react it with a strong acid like sulfuric acid (H2SO4). Here's the balanced chemical equation:

   ZnO + H2SO4 → ZnSO4 + H2O

   In this reaction, zinc oxide reacts with sulfuric acid to form zinc sulfate and water.

So, the overall sequence of reactions is:

ZnS (Zinc Sulfide) → ZnO (Zinc Oxide) → ZnSO4 (Zinc Sulfate)

These reactions can be useful in various chemical processes, including the extraction and processing of zinc-containing ores.
