After two experiments, get copper oxide (2) from copper chloride (2).

In order for everything to work out, first:
We obtain hydroxide from copper chloride by adding alkali;
After that, the obtained copper hydroxide is decomposed by heating into oxide and water, and copper oxide (CuO) is obtained.
Equations for these experiments.
CuCl2 + 2NaOH = Cu (OH) 2 + 2NaCl;
Cu (OH) 2 (heating process) = CuO + H2O.

One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
