Question

CU-CuO-CuCl2-Cu(OH)2-CuO-CuSO4-CuS

Answer 1

Ответ:

2Сu+O2=2CuO

CuO+2HCl=CuCl2+H2O

CuCl2+2NaOH=Cu(OH)2+2NaCl

Cu(OH)2=CuO+H2O

CuO+H2SO4=CuSO4+H2O

Answer 2

The sequence you provided appears to be a series of chemical reactions involving copper compounds. Let's break down each step of the reaction:

1. Cu: This represents elemental copper. The symbol "Cu" is the chemical symbol for copper, which is a transition metal with the atomic number 29.

2. CuO: This is copper(II) oxide, which is a compound consisting of copper and oxygen. The "II" in parentheses indicates the oxidation state of copper, which is +2 in this compound.

3. CuCl2: This represents copper(II) chloride. It is a compound formed when copper reacts with chlorine in the +2 oxidation state.

4. Cu(OH)2: This is copper(II) hydroxide, which is formed when copper(II) ions react with hydroxide ions (OH-) to form a solid precipitate.

5. CuO: Copper(II) oxide appears again in the sequence. It is likely a typographical repetition since it was already mentioned earlier.

6. CuSO4: This is copper(II) sulfate, a compound formed when copper reacts with sulfuric acid.

7. CuS: This represents copper(II) sulfide, a compound formed when copper reacts with sulfur.

The overall reaction sequence seems to be a combination of different copper reactions and their products. Keep in mind that without specific reaction conditions or amounts of reactants, it's challenging to determine the overall balanced chemical equation for this sequence.
