Question

Na NaH NaOH NaHCO3 Na2SO4 NaOH NaClO3

Answer 1

2Na + H2 = 2NaH
NaH + H2O = NaOH + H2
NaOH + CO2 = NaHCO3
2NaHCO3 + H2SO4 = Na2SO4 + 2CO2 + 2H2O
Na2SO4 + Ba(OH)2 = BaSO4 + 2NaOH
NaOH + HClO3 = NaClO3 + H2O

Answer 2

Sodium metal (Na), sodium hydride (NaH), sodium hydroxide (NaOH), sodium bicarbonate (NaHCO3), sodium sulfate (Na2SO4), sodium hydroxide (NaOH), and sodium chlorate (NaClO3).
