Question

Cu - CuO- CuCl2 - Cu Помогите с СuCl2 - Cu

Answer 1

2Cu + O2 = 2CuO

CuO + 2HCl = CuCl2 + H2O

CuCl2 + Zn = ZnCl2 + Cu

Answer 2

CuCl2 is copper (II) chloride, which is a compound composed of copper and chlorine. It is typically a greenish-blue solid at room temperature and is soluble in water.

To obtain copper metal (Cu) from CuCl2, you will need to perform a reduction reaction. One way to do this is to react CuCl2 with a reducing agent such as metallic zinc (Zn). The reaction can be represented by the following equation:

CuCl2 + Zn → ZnCl2 + Cu

In this reaction, the zinc (Zn) is oxidized to form zinc chloride (ZnCl2), and the copper (II) ion in the CuCl2 is reduced to form copper metal (Cu). The copper metal will form as a solid and can be separated from the reaction mixture by filtration or decantation.

It's important to note that this reaction should be conducted with caution as CuCl2 is a hazardous chemical and should be handled with proper safety precautions.
