The assignment is not written quite correctly. It should look like this:
CuSO4 – Cu (OH) 2 – CuO – CuCl2.
Let’s start with the first reaction equation.
CuSO4 + 2NaOH = Cu (OH) 2 (precipitates) + Na2SO4.
We write down the complete and abbreviated ionic equation:
Cu (2+) + SO4 (2-) + 2Na (+) + 2OH (-) = Cu (OH) 2 + 2Na (+) + SO4 (2-).
Cu (2+) + 2OH (-) = Cu (OH) 2.
The next reaction takes place under the additional condition – temperature:
2Cu (OH) 2 = 2CuO + 2H2O.
CuO + 2HCl = CuCl2 + H2O.
CuO + 2H (+) + 2Cl (-) = Cu (2+) + 2Cl (-) + H2O.
CuO + 2H (+) = Cu (2+) + H2O.
