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
