Answer 3

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

Cu-CuO-CuCl2-Cu(OH)2-CuCl2-Cu is a series of chemical reactions involving copper compounds. Here is a breakdown of the reactions:

1. Cu + CuO: The reaction between copper (Cu) and copper(II) oxide (CuO) results in the formation of copper(I) oxide (Cu2O) [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap). 2. CuO + 2HCl: Copper(II) oxide reacts with hydrochloric acid (HCl) to produce copper(II) chloride (CuCl2) and water (H2O). 3. Cu(OH)2 + 2HCl: Copper(II) hydroxide (Cu(OH)2) reacts with hydrochloric acid to form copper(II) chloride and water. 4. Cu(OH)2: Copper(II) hydroxide can decompose into copper(II) oxide and water. 5. CuCl2 + Cu: Copper(II) chloride reacts with copper to produce copper(I) chloride (CuCl).
