Question

Химия: Na- na2o2- naoh- nahco3- co2- ba(hco3)2- baco3

ник4898 · Answer

1) 2Na + O₂ = Na₂O₂2) 2Na₂O₂ + H₂O = 4NaOH + O₂3) NaOH + H₂CO₃ = NaHCO₃ + H₂O4) NaHCO₃ + HCl = NaCl + CO₂ + H₂O5) CO₂ + Ba(OH)₂ = Ba(HCO₃)₂6) Ba(HCO₃)₂ = BaCO₃ + H₂O + CO₂...

Na-> na2o2-> naoh-> nahco3-> co2-> ba(hco3)2-> baco3
