Question

Cu = CuSO4 = Cu(OH)2 = CuO = Cu = CuO = CuCl2 = HCl​

Answer 1

Ответ:

Объяснение:

Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O

CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4

Cu(OH)2 -> CuO + H2O

CuO + Mg = MgO + Cu

2Cu + O2 = 2CuO

CuO +2HCl = CuCl2 + H2O

3CuCl2 + 2H3PO4 = Cu3(PO4)2 + 6HCl

Answer 2

It seems like you've listed several chemical compounds and equations involving copper (Cu) and hydrochloric acid (HCl). Let's clarify each of them:

1. Cu: This symbol represents copper, a metallic element.

2. CuSO4: This is copper(II) sulfate, a compound containing copper, sulfur, and oxygen.

3. Cu(OH)2: This is copper(II) hydroxide, a compound containing copper and hydroxide ions.

4. CuO: This is copper(II) oxide, a compound containing copper and oxygen.

5. CuCl2: This is copper(II) chloride, a compound containing copper and chlorine.

6. HCl: This is hydrochloric acid, a strong acid composed of hydrogen and chlorine.

There is a bit of confusion in your statement. The listed compounds are not entirely equivalent to one another, but they can be related through chemical reactions.

• CuSO4 can be formed by the reaction of copper with sulfuric acid (H2SO4).
• Cu(OH)2 can be formed by the reaction of copper(II) salts with hydroxide ions.
• CuO can be formed by the heating of copper(II) hydroxide.
• CuCl2 can be formed by the reaction of copper with hydrochloric acid (HCl).

To summarize, the listed compounds are related to copper and can be connected through various chemical reactions, but they are not all the same substance.
