Question

ZnSO4-Zn(OH)2-ZnO-Zn(NO3)2

Answer 1

ZnSO4 + 2KOH = Zn(OH)2 + K2SO4
Zn(OH)2 =t= ZnO + H2O
ZnO + 2HNO3 = Zn(NO3)2 + H2O

Answer 2

ZnSO4+2NaOH->Na2SO4+Zn(OH)2
Zn(OH)2->ZnO+H2O
ZnO+2HNO3->Zn(NO3)2+H2O

Answer 3

The sequence you provided represents a series of chemical reactions involving zinc compounds. Let's break it down step by step:

1. ZnSO4: This is zinc sulfate, which is a chemical compound containing zinc (Zn) and sulfate (SO4) ions.

2. Zn(OH)2: This is zinc hydroxide, which is a white precipitate formed when zinc ions react with hydroxide ions (OH-) in a basic solution.

The reaction between ZnSO4 and a base (e.g., NaOH or KOH) would yield Zn(OH)2:

ZnSO4 + 2 NaOH → Zn(OH)2 + Na2SO4

3. ZnO: This is zinc oxide, a white powder that can be obtained from the thermal decomposition of zinc hydroxide or by heating zinc metal in the presence of oxygen.

Zn(OH)2 → ZnO + H2O

4. Zn(NO3)2: This is zinc nitrate, a chemical compound composed of zinc (Zn) and nitrate (NO3) ions.

The reaction between zinc oxide and nitric acid (HNO3) would yield zinc nitrate:

ZnO + 2 HNO3 → Zn(NO3)2 + H2O

The overall reaction sequence can be summarized as follows:

ZnSO4 + 2 NaOH → Zn(OH)2 + Na2SO4 Zn(OH)2 → ZnO + H2O ZnO + 2 HNO3 → Zn(NO3)2 + H2O

Please note that in practical applications, these reactions may require specific conditions such as temperature, concentration, and catalysts to proceed efficiently. Additionally, the stoichiometry and details of the reactions may vary depending on the specific reaction conditions.
