Question

CUCO3-CUCL2-CU(OH)2-CUSO4

Answer 1

CuCO3 + 2HCl = CuCl2 + H2O + CO2
CuCl2 + 2NaOH = Cu(OH)2 + 2NaCl
Cu(OH)2 + H2SO4 = CuSO4 + 2H2O

Answer 2

The chemical reactions you provided involve the compounds CuCO3, CuCl2, Cu(OH)2, and CuSO4. Let's break down the reactions step by step:

1. CuCO3: - CuCO3 can react with NaOH to form Cu(OH)2 and Na2CO3. - The balanced equation for this reaction is: CuCO3 + 2NaOH → Cu(OH)2 + Na2CO3.

2. CuCl2: - CuCl2 can react with NaOH to form Cu(OH)2 and NaCl [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap). - The balanced equation for this reaction is: CuCl2 + 2NaOH → Cu(OH)2 + 2NaCl.

3. Cu(OH)2: - Cu(OH)2 can react with HCl to form CuCl2 and H2O [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap). - The balanced equation for this reaction is: Cu(OH)2 + 2HCl → CuCl2 + 2H2O.

4. CuSO4: - CuSO4 can react with NaOH to form Cu(OH)2 and Na2SO4 [[1]](https://uchi.ru/otvety/questions/1-osuschestvite-tsepochku-prevrascheniy-1-cuso4-cu-oh-2-cuo-cucl2-uravneniya-reaktsiy-zap). - The balanced equation for this reaction is: CuSO4 + 2NaOH → Cu(OH)2 + Na2SO4.
