| The following substances are given O2, H2O, Na, KOH, CuO, NaOH, Na2SO4, SO3, HCL, Na2O, CuSO4. Analyze them and find the genetical connection between them. Prove her benign transformations
4Na + O2 = 2Na2O (sodium oxide – basic oxide);
Na2O + H2O = 2NaOH (sodium hydroxide – alkali, water-soluble base);
NaOH + HCl = NaCl + H2O (sodium chloride – salt);
2NaOH + SO3 = Na2SO4 + H2O (sodium sulfate – salt);
SO3 + H2O = H2SO4 (sulfuric acid);
Na2O + SO3 = Na2SO4 (sodium sulfate – salt);
CuO + H2SO4 = CuSO4 + H2O (copper sulfate – salt);
2KOH + H2SO4 = K2SO4 + H2O (potassium sulfate – salt).
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.
