Question

Zn-ZnSO4-Zn(OH)2-ZnO-ZnCl2

Answer 1

Zn+H2SO4=ZnSO4+H2
ZnSO4+2NaOH=Zn(OH)2+Na2SO4
Zn(OH)2=ZnO+H2O
ZnO+2HCl=ZnCl2+H2O

Answer 2

The given sequence represents a series of chemical reactions involving zinc (Zn) and various compounds. Let's break down each step:

1. Zn: This represents elemental zinc, which is the pure form of the metal.

2. ZnSO4: This represents zinc sulfate, which is a compound formed when zinc reacts with sulfuric acid (H2SO4). The reaction can be represented as follows: Zn + H2SO4 -> ZnSO4 + H2

3. Zn(OH)2: This represents zinc hydroxide, which is formed when zinc sulfate reacts with sodium hydroxide (NaOH) or any other hydroxide source. The reaction can be represented as follows: ZnSO4 + 2NaOH -> Zn(OH)2 + Na2SO4

4. ZnO: This represents zinc oxide, which is formed when zinc hydroxide is heated or undergoes thermal decomposition. The reaction can be represented as follows: 2Zn(OH)2 -> 2ZnO + 2H2O

5. ZnCl2: This represents zinc chloride, which is formed when zinc oxide reacts with hydrochloric acid (HCl). The reaction can be represented as follows: ZnO + 2HCl -> ZnCl2 + H2O

Overall, the sequence represents a series of chemical transformations involving zinc and various compounds: zinc sulfate, zinc hydroxide, zinc oxide, and zinc chloride.
