Question

CuSO4-Cu(OH)2-CuO-CuCl2-Cu

Answer 1

Ответ:

Объяснение:

CuSO4 + 2KOH → Cu(OH)2 = K2SO4

Cu(OH)2 →  CuO + H2O

CuO + 2HCl →CuCl2 + H2O

CuCl2 → Cu + Cl2

Answer 2

It seems like you've listed a sequence of chemical compounds that involve copper ions in various oxidation states. These compounds are:

1. CuSO4 - Copper(II) sulfate: This is a compound containing copper ions in the +2 oxidation state. It's commonly used in agriculture as a fungicide and in chemistry laboratories for various applications.

2. Cu(OH)2 - Copper(II) hydroxide: This is another compound containing copper ions in the +2 oxidation state. It's a blue precipitate and can be formed by mixing a copper salt with a base.

3. CuO - Copper(II) oxide: This compound contains copper ions in the +2 oxidation state. It's a black solid and is often used as a pigment in ceramics and glass.

4. CuCl2 - Copper(II) chloride: Once again, this compound contains copper ions in the +2 oxidation state. It's used in various industrial processes and can also serve as a catalyst in chemical reactions.

5. Cu - Elemental copper: This refers to copper in its zero oxidation state. It's the pure form of copper, often used for electrical wiring, plumbing, and various other applications.
