The reactions are shown below:
1) Reaction of ethanoic acid with sodium carbonate:
$2C{H}_{3}COOH+N{a}_{2}C{O}_3\to 2{\mathrm{CH}}_3\mathrm{COONa}+H_{2}O+{\mathrm{CO}}_2$

2) Reaction of ethanoic acid with sodium hydrogencarbonate:
${\mathrm{CH}}_3\mathrm{COOH}+{\mathrm{NaHCO}}_3\to {\mathrm{CH}}_3\mathrm{COONa}+H_{2}O+{\mathrm{CO}}_2$
