Question

Помогите сделать цепочку преврещений плиз CuCl2 -> CuCO3 -> CuO -> Cu(NO3)2 -> Cu(OH)2

Answer 1

1)CuCl+H2CO3=CuCO3+2HCl
2)CuCO3+NaO=CuO+NaCO3
3)CuO+HNO3=Cu(NO3)2+H2
4)Cu(NO3)2+KOH=Cu(OH)2+KNO3

Answer 2

1. CuCl2 (copper (II) chloride) - This is a compound consisting of copper and chlorine.

2. CuCO3 (copper (II) carbonate) - This is a compound formed when copper (II) ions react with carbonate ions.

3. CuO (copper (II) oxide) - This is formed when copper (II) carbonate is heated, causing it to decompose and release carbon dioxide, leaving behind copper (II) oxide.

4. Cu(NO3)2 (copper (II) nitrate) - This is formed when copper (II) oxide reacts with nitric acid.

5. Cu(OH)2 (copper (II) hydroxide) - This is formed when copper (II) nitrate reacts with sodium hydroxide, resulting in the precipitation of copper (II) hydroxide.

So, the complete transformation chain is: CuCl2 -> CuCO3 -> CuO -> Cu(NO3)2 -> Cu(OH)2
