Question

CU-Cuo-cucl2-cu(oh)2-cuo-cuso4

Answer 1

2Сu+O2=2CuO

CuO+2HCl=CuCl2+H2O

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

Cu(OH)2=CuO+H2O

CuO+H2SO4=CuSO4+H2O

Answer 2

2Сu+O2=2CuO

CuO+2HCl=CuCl2+H2O

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

Cu(OH)2=CuO+H2O

CuO+H2SO4=CuSO4+H2O

Answer 3

The chemical reaction you provided seems to depict a series of reactions involving copper (Cu) and various compounds. Here's a breakdown of each step:

1. Cu + CuCl2: In this reaction, copper (Cu) reacts with copper chloride (CuCl2) to form a new compound. The balanced chemical equation for this reaction is:

2Cu + CuCl2 → 3CuCl

2. CuCl + Cu(OH)2: Here, copper(II) chloride (CuCl) reacts with copper(II) hydroxide (Cu(OH)2) to form another compound. The balanced chemical equation for this reaction is:

2CuCl + Cu(OH)2 → CuCl2 + 2Cu(OH)

3. Cu(OH) + CuO: In this reaction, copper(II) hydroxide (Cu(OH)2) reacts with copper(II) oxide (CuO) to form a new compound. The balanced chemical equation for this reaction is:

2Cu(OH)2 → CuO + H2O

4. CuO + CuSO4: Lastly, copper(II) oxide (CuO) reacts with copper(II) sulfate (CuSO4) to form another compound. The balanced chemical equation for this reaction is:

CuO + CuSO4 → Cu2O + SO3

Overall, the reaction sequence you provided can be summarized as follows:

2Cu + CuCl2 → 3CuCl 2CuCl + Cu(OH)2 → CuCl2 + 2Cu(OH) 2Cu(OH)2 → CuO + H2O CuO + CuSO4 → Cu2O + SO3
