Question

H2O-H2SO4-ZnSO4-Zn(OH)2-H2O​

Answer 1

Ответ:

Объяснение:

H2O + SO3 = H2SO4

H2SO4 + Zn = ZnSO4 + H2↑

ZnSO4 + 2NaOH = Zn(OH)2↓ + Na2SO4

Zn(OH)2 ->ZnO + H2O

Answer 2

The given sequence of chemical reactions appears to be the process of reacting water (H2O) with sulfuric acid (H2SO4) and then subsequently with zinc sulfate (ZnSO4) to form zinc hydroxide (Zn(OH)2) and water (H2O) again.

Let's break down each step of the reaction:

1. H2O (water) reacts with H2SO4 (sulfuric acid) to form a new compound, possibly a hydronium ion (H3O+) and sulfate ion (SO4^2-):

H2O + H2SO4 → H3O+ + SO4^2-

2. The second step involves the reaction of H3O+ with ZnSO4 (zinc sulfate) to produce zinc hydroxide (Zn(OH)2) and sulfuric acid (H2SO4):

H3O+ + ZnSO4 → Zn(OH)2 + H2SO4

3. Finally, zinc hydroxide (Zn(OH)2) might react with water (H2O) to regenerate zinc sulfate (ZnSO4):

Zn(OH)2 + H2O → ZnSO4 + H2O

It's important to note that the reactions above are simplified, and the actual reactions might involve more intermediate steps or side reactions, depending on the specific conditions and concentrations of the reactants.
