Question

Cu cuo cucl2 cu(oh)2 cuo cu cuso4 cu(oh)2

Answer 1

1)2 Сu +O2 = 2CuO

2) CuO +2 HCl = CuCl2 + H2O

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

4) Cu(OH)2 = CuO + H2O

5) 2CuO = 2Cu + O2

6) Cu + 2H2SO4 = CuSO4 + SO2 + 2H2O

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

Answer 2

It looks like you've provided a list of chemical compounds and their chemical formulas, primarily involving copper (Cu) ions. Here's a breakdown of each compound:

1. Cu: This represents elemental copper, which consists of copper atoms.

2. CuCl2: This is copper(II) chloride, which consists of copper ions (Cu²⁺) and chloride ions (Cl⁻).

3. Cu(OH)2: This is copper(II) hydroxide, which consists of copper ions (Cu²⁺) and hydroxide ions (OH⁻).

4. CuO: This is copper(II) oxide, which consists of copper ions (Cu²⁺) and oxygen ions (O²⁻).

5. CuSO4: This is copper(II) sulfate, which consists of copper ions (Cu²⁺) and sulfate ions (SO₄²⁻).

6. Cu(OH)2: This is copper(II) hydroxide, as mentioned earlier.
