(a)
CO₂(g) + 2NaOH(aq) → Na₂CO₃(aq) + H₂O(l)
(If CO₂ is in excess :)
(CO₂(g) + Na₂CO₃(aq) + H₂O(l) → 2NaHCO₃(aq))
(b)
Na₂O(s) + 2HNO₃(aq) → 2NaNO₃(aq) + H₂O(l)
CO₂(g) + 2NaOH(aq) → Na₂CO₃(aq) + H₂O(l)
(If CO₂ is in excess :)
(CO₂(g) + Na₂CO₃(aq) + H₂O(l) → 2NaHCO₃(aq))
(b)
Na₂O(s) + 2HNO₃(aq) → 2NaNO₃(aq) + H₂O(l)

(a) = CO2 + NaOH = NaHCO3 ( Sodium bi-carbonate or sodium hydrogen carbonate).
(b) = Na2O + 2HNO3 = 2NaNO3 + H2O
(b) = Na2O + 2HNO3 = 2NaNO3 + H2O
