Make up the equations of interaction reactions: 1) hydrochloric acid and sodium hydroxide; 2) hydrochloric acid and copper (II) hydroxide; 3) hydrochloric acid with copper (II) oxide; 4) copper (II) sulfate and sodium hydroxide; 5) decomposition of hydroxide.

1) HCl + NaOH = NaCl + H2O (when hydrochloric acid interacts with sodium hydroxide, sodium chloride and water are formed);

2) 2HCl + Cu (OH) 2 = CuCl2 + 2H2O (when hydrochloric acid interacts with copper (II) hydroxide, copper chloride and water are formed);

3) 2HCl + CuO = CuCl2 + H2O (when hydrochloric acid interacts with copper (II) oxide, copper chloride and water are formed);

4) CuSO4 + 2NaOH = Cu (OH) 2 + Na2SO4 (when copper sulfate reacts with sodium hydroxide, copper hydroxide and sodium sulfate 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.
