Question

Cu-cuo-cucl2-cu(oh 2)-cu(no3)2 cuso4 пожалуйста помогите мне химия ​

Answer 1

Ответ:

2Cu+O2=2CuO (t)

CuO+2HCl=CuCl2+H2O

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

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

Cu(NO3)2+H2SO4(k)=CuSO4+2HNO3

Объяснение:

Answer 2

Cu-CuO-CuCl2-Cu(OH)2-Cu(NO3)2-CuSO4

Cu (copper) can form various compounds with different oxidation states. Let's break down the compounds you mentioned:

1. Cu - This refers to elemental copper, which is a reddish-brown metal. It is commonly used in electrical wiring, plumbing, and various industrial applications.

2. CuO - This is copper(II) oxide, which is a black solid. It is formed when copper reacts with oxygen. Copper(II) oxide is used as a pigment in ceramics and as a catalyst in chemical reactions.

3. CuCl2 - This is copper(II) chloride, which is a greenish-blue solid. It is formed when copper reacts with chlorine. Copper(II) chloride is used in various industrial processes, such as electroplating and as a catalyst in organic reactions.

4. Cu(OH)2 - This is copper(II) hydroxide, which is a pale blue solid. It is formed when copper reacts with water or a base. Copper(II) hydroxide is used as a fungicide and as a precursor for the production of other copper compounds.

5. Cu(NO3)2 - This is copper(II) nitrate, which is a blue crystalline solid. It is formed when copper reacts with nitric acid. Copper(II) nitrate is used in the production of catalysts, dyes, and pigments.

6. CuSO4 - This is copper(II) sulfate, which is a blue crystalline solid. It is formed when copper reacts with sulfuric acid. Copper(II) sulfate is used in agriculture as a fungicide and herbicide, as well as in the production of pigments, batteries, and electroplating.
