The following substances are given O2, H2O, Na, KOH, CuO, NaOH, Na2SO4, SO3, HCL

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).
