The equation NaHco3+hc2h3o2=nac2h3o2+h2co3 is already balanced.
Reaction information:
Nahcolite + Acetic Acid = Sodium Acetate + Carbonic Acid
Reactants:
Nahcolite - NaHCO3 :
Molar Mass, Oxidation State
Acetic Acid - HC2H3O2
Molar Mass, Oxidation State, Ethanoic Acid, Methanecarboxylic Acid, Ch3-Cooh, Acetic Acid; Glacial, etc
(NaHCO3 + HC2H3O2 = NaC2H3O2 + H2CO3)
