2Na + O2 = Na2O2

2Na2O2 + 2H2O = 4NaOH + O2

NaOH + CH3COOH = CH3COONa + H2O

CH3COONa + NaOH = CH3COOH + Na2CO3

Na2CO3 + 2HBr = 2NaBr + H2O + CO2

2NaBr + Cl2 = 2NaCl + Br2

2NaCl = Na + Cl2(электролиз расплава)

1)2Na + O2 = Na2O2

2)2Na2O2 + 2H2O = 4NaOH + O2

3)NaOH + CH3COOH = CH3COONa + H2O

4)CH3COONa + NaOH = CH3COOH + Na2CO3

5)Na2CO3 + 2HBr = 2NaBr + H2O + CO2

6)2NaBr + Cl2 = 2NaCl + Br2

7)2NaCl = Na + Cl2
