Question

Сu → СuСl 2 → Сu(ОН) 2 → СuО→ Сu(NО 3 ) 2 → NО 2

Answer 1

Ответ:

Объяснение:

Сu → СuСl₂ → Сu(ОН)₂ → СuО→ Сu(NО₃)₂ → NО₂

Сu+CI₂= СuСl₂

СuСl₂+2NaOH =Сu(ОН)₂↓+2NaCI

Сu(ОН)₂+(t°C) =СuО+H₂O

СuО+HNO₃= Сu(NО₃)₂+H₂O

2Сu(NО₃)₂ =2CuO+4NО₂+3O₂↑

Answer 2

It seems like you've provided a sequence of chemical reactions involving copper (Cu) and other compounds. This series of reactions appears to depict the conversion of copper to various compounds through different chemical reactions. Let me explain each step of the sequence:

1. Cu: This represents metallic copper in its elemental form.

2. CuCl2: Copper(II) chloride. Copper reacts with chlorine gas to form copper chloride.

3. Cu(OH)2: Copper(II) hydroxide. Copper chloride reacts with sodium hydroxide (NaOH) to form copper hydroxide and sodium chloride.

4. CuO: Copper(II) oxide. Copper hydroxide undergoes dehydration to form copper oxide and water.

5. Cu(NO3)2: Copper(II) nitrate. Copper oxide reacts with nitric acid (HNO3) to form copper nitrate and water.

6. NO2: Nitrogen dioxide. Copper(II) nitrate undergoes thermal decomposition to form copper oxide and nitrogen dioxide gas.

Each step of the sequence involves different reactions and chemical changes that lead to the formation of various copper compounds and nitrogen dioxide. If you have any specific questions about these reactions or need further clarification, feel free to ask!
