Write the reaction equations Na → NaOH → Na2SO4 → NaCl → Na

1) 2Na + 2H2O = 2NaOH + H2 (when sodium interacts with water, sodium hydroxide and hydrogen are formed);
2) 2NaOH + H2SO4 = Na2SO4 + 2H2O (when sodium hydroxide interacts with sulfuric acid, sodium sulfate and water are formed);
3) Na2SO4 + BaCl2 = 2NaCl + BaSO4 (when sodium sulfate interacts with barium chloride, sodium chloride and barium sulfate are formed);
4) 2NaCl = 2Na + Cl2 (during electrolysis, sodium chloride decomposes into sodium and chlorine).
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.
