Question

. Запишите уравнения реакции по цепочке химических превращений: CuSO4 → Cu (OH)2 → CuO

Answer 1

1) $CuSO_{4} +2H_{2}O=Cu(OH)_{2} +H_{2}SO_{4}$
2) $Cu(OH)_{2} =CuO+H_{2}O$

Answer 2

CuSO4+2NaOH->Cu(OH)2+Na2SO4
Cu(OH)2->CuO+H2O

Answer 3

Уравнения реакции по цепочке химических превращений:

1. CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4 [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap) - CuSO4 reacts with NaOH to form Cu(OH)2 and Na2SO4.

2. Cu(OH)2 + 2HCl → CuCl2 + 2H2O [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap) - Cu(OH)2 reacts with HCl to form CuCl2 and H2O.

3. Cu(OH)2 → CuO + H2O [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap) - Cu(OH)2 decomposes to form CuO and H2O.

Therefore, the overall reaction can be represented as:

CuSO4 + 2NaOH + 2HCl → CuCl2 + 2H2O + Na2SO4

Please note that the reaction pathway and conditions may vary depending on the specific experimental setup and reaction conditions.
