Question

CuO=CuSo4=Cu(OH)2=CuCl2

Answer 1

СuO + H2SO4 = CuSO4 + H2O
CuSO4 + 2KOH = Cu(OH)2  синий осадок + K2SO4 
Cu(OH)2 + 2HCl = CuCl2 + H2O 

Answer 2

It seems there is a mix-up in the chemical formulas you provided. Let's clarify the correct formulas for each compound:

1. CuO: This represents copper(II) oxide, which is a black solid compound consisting of copper and oxygen (CuO).

2. CuSO4: This represents copper(II) sulfate, a blue crystalline compound consisting of copper, sulfur, and oxygen (CuSO4). It's important to note that CuSO4 is different from CuO.

3. Cu(OH)2: This represents copper(II) hydroxide, a pale blue solid compound consisting of copper, hydrogen, and oxygen (Cu(OH)2). Again, this is different from CuO and CuSO4.

4. CuCl2: This represents copper(II) chloride, a greenish-brown solid compound consisting of copper and chlorine (CuCl2). Once more, this is different from the previous compounds.

Each of these compounds is unique and has distinct properties and applications in various chemical processes. If you have any specific questions about these compounds or need further information, feel free to ask!
