Question

Zn---ZnCl2---Zn(OH)2---ZnO---ZnSO4---Zn(NO)2

Answer 1

1) Zn+2HCl—> ZnCl2 + H2O
2) ZnCl2 + 2NaOH—> ZN(OH)2+ 2NaCl
3) Zn(OH)2–> ZnO + H2O
4) ZnO+ H2SO4–> ZnSO4+H2O
5) ZnSO4 + 2HNO3–> Zn(NO3)2 + H2SO4

Answer 2

The sequence you provided represents a series of chemical reactions involving zinc (Zn) and various compounds. Here is a breakdown of each step in the sequence:

1. Zn: This represents elemental zinc, which is a metallic element commonly used in various applications.

2. ZnCl2: Zinc chloride is formed when zinc reacts with chlorine gas (Cl2). It is a white crystalline solid and is often used as a reagent in chemical reactions.

3. Zn(OH)2: Zinc hydroxide is obtained when zinc chloride reacts with a base such as sodium hydroxide (NaOH). It is a white precipitate that is sparingly soluble in water.

4. ZnO: Zinc oxide is formed when zinc hydroxide is heated or exposed to air. It is a white powder and is commonly used in the production of various products, including sunscreens, ceramics, and pigments.

5. ZnSO4: Zinc sulfate is obtained when zinc oxide reacts with sulfuric acid (H2SO4). It is a white crystalline solid and is used in several industries, including agriculture and pharmaceuticals.

6. Zn(NO)2: Zinc nitrate is formed when zinc reacts with nitric acid (HNO3). It is a white crystalline solid and is commonly used in the production of other zinc compounds or as a reagent in chemical reactions.

Each step in this sequence represents a different reaction or transformation of zinc, resulting in the formation of various zinc compounds.
