Question

Cuso4-co(oh)2-cuo-cucl2-cu(no3)2-cus

Answer 1

1)CuSO₄+2NaOH→Cu(OH)₂↓+Na₂SO₄

2)Cu(OH)₂(+t°)→CuO+H₂O

3)СuO+2HCl→CuCl₂+H₂O

4)CuCl₂+2AgNO₃→2AgCl↓+Cu(NO₃)₂

5)Cu(NO₃)₂+Na₂S→CuS↓+2NaNO₃

Answer 2

The given sequence of compounds seems to represent a series of reactions involving copper ions. Here's a breakdown of the compounds and the possible reactions involved:

1. CuSO4: Copper(II) sulfate. It is a salt containing copper ions in the +2 oxidation state.

2. Co(OH)2: Cobalt(II) hydroxide. This compound does not directly relate to copper, so it's unclear how it fits into the sequence.

3. CuO: Copper(II) oxide. It can be formed by heating copper(II) hydroxide, which might suggest a reaction between CuSO4 and Co(OH)2.

4. CuCl2: Copper(II) chloride. This compound could potentially be obtained by reacting CuO with HCl.

5. Cu(NO3)2: Copper(II) nitrate. This compound can be formed by reacting CuO with nitric acid (HNO3).

6. CuS: Copper(II) sulfide. This compound might be obtained by reacting Cu(NO3)2 with hydrogen sulfide (H2S).

Please note that the reactions and product compounds mentioned above are speculative based on the given compounds. The actual reaction pathway and products would depend on the specific conditions, reactant concentrations, and stoichiometry used in the reactions.
