1. CH3COOH + NaHCO3 → CO2 + H2O + Na+ + CH3COO-

acid base salt

Acid/base neutralization followed by decomposition

The acid first reacts with the base to form carbonic acid, H2CO3. Then the H2CO3 decomposes into CO2 and H2O.

CH3COOH + NaHCO3 → H2CO3 + CH3COO - + Na+

H2CO3 → CO2 + H2O

2. CaCl2 + 2NaHCO3 → CO2 + CaCO3 + 2NaCl + H2O

Double displacement, then acid/base neutralization, then decomposition.

CaCl2 + NaHCO3 → CaCO3 + HCl + NaCl (double displacement — 1Ca replaces 1Na + 1H))

NaHCO3 + HCl → H2CO3 + NaCl (acid/base neutralization)

H2CO3 → CO2 + H2O (decomposition)
