Удачи !!!

Answer 2

Объяснение:

1. Cu+4HNO3(конц)=Cu(NO3)2+2NO2+2H2O
2. 2Cu(NO3)=2CuO+4NO2+O2
3. CuO+2HNO3(р-р)=Cu(NO3)2+H2O
4. Cu(NO3)2+Fe=Fe(NO3)2+Cu
5. Fe(NO3)2+2KOH=Fe(OH)2+2KNO3
6. 2KNO3=2KNO2+O2

Answer 3

It seems like you've listed a series of chemical reactions involving copper (Cu) and its various compounds. Let's go through each step:

1. Cu: This represents elemental copper, which is a metal.

2. Cu(NO3)2: Copper(II) nitrate, Cu(NO3)2, is a compound formed by copper reacting with nitric acid. It is often a blue solution or solid and is a common copper salt.

3. CuO: Copper(II) oxide, CuO, is a black solid that is formed when elemental copper (Cu) reacts with oxygen (O2) in the air.

4. CuSO4: Copper(II) sulfate, CuSO4, is a blue crystalline compound formed by the reaction of copper with sulfuric acid (H2SO4).

5. Cu: After copper has undergone various chemical reactions, it can be reduced back to its elemental form, Cu.

6. Cu(OH)2: Copper(II) hydroxide, Cu(OH)2, is a blue-green solid formed when copper ions react with hydroxide ions.

These reactions represent various chemical transformations that copper can undergo, including oxidation, reduction, and the formation of different copper compounds. Is there something specific you would like to know or discuss about these reactions?
