1) Cu + Cl2 = CuCl2 (when copper interacts with chlorine, copper chloride is formed);
2) CuCl2 + Zn = ZnCl2 + Cu (when copper chloride interacts with zinc, zinc chloride and copper are formed);
3) Cu + S = CuS (when copper interacts with sulfur, copper sulfide is formed);
4) CuS + 2NaOH = Cu (OH) 2 + Na2S (when copper sulfide interacts with sodium hydroxide, copper hydroxide and sodium sulfide are formed).
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.
