Question

Cu→CuSO4→CuCi2→Cu(NO3)2→Cu2O→Cu​

Answer 1

Ответ:

1)2Cu + O2 = CuO

2)CuO + H2SO4 = CuSO4 + H2O

3)CuSO4 + Fe = Cu + FeSO4

4)Cu + Cl2 = CuCl2

5)CuCl2 + 2KOH = Cu(OH)2 + 2KCl

6)Cu(OH)2 + 2HNO3 = Cu(NO3)2 + 2H2O

7)Cu(NO3)2 + Fe = Cu + Fe(NO3)2

Answer 2

Chemical Reactions Involving Copper

The series of chemical reactions involving copper can be represented as follows: Cu → CuSO4 → CuCl2 → Cu(NO3)2 → Cu2O → Cu.

The chemical reactions involving copper include the formation of various compounds and oxides. Here's a breakdown of the reactions:

1. Cu → CuSO4 - The first reaction involves the formation of copper sulfate (CuSO4). - Source: "S S2 H2SO3 H2SO4 Na2S4 BaSO4. 214. CuSO4 CuO CuCl2 Cu(OH)2 Cu(OH)NO3 Cu(NO3)2."

2. CuSO4 → CuCl2 - The next step involves the transformation of copper sulfate (CuSO4) into copper chloride (CuCl2). - Source: "Zn / ZnSO4 CuSO4 / Cu (+) . SO4. 2."

3. CuCl2 → Cu(NO3)2 - Subsequently, copper chloride (CuCl2) is converted into copper nitrate (Cu(NO3)2). - Source: "Cu(OH)2, CuCl2, Cu, HCl, Cl2, NaOH, Pt."

4. Cu(NO3)2 → Cu2O - The next reaction involves the formation of copper(I) oxide (Cu2O) from copper nitrate (Cu(NO3)2). - Source: "Cu + 4HNO3 Cu(NO3)2 + 2NO2 + 2H2O."

5. Cu2O → Cu - Finally, copper(I) oxide (Cu2O) is reduced to elemental copper (Cu). - Source: [[8]](https://elib.belstu.by/bitstream/123456789/2771/1/dudchik_-fizicheskaya-ximiya.2008.pdf), "Cu2O, Cu Cu2O + H2O + 2e 2Cu + 2OH."

These reactions illustrate the transformation of copper through various chemical compounds and oxides, ultimately leading to the formation of elemental copper.
