What is the correct chemical equation for vinegar and baking soda?

I am trying to put lesson plans together for a basic, introductory chemistry class I am teaching this summer. On the internet, I have found 2 different chemical equations for the vinegar/baking soda reaction. Equation 1: CH3COOH + NaHCO3 ---> CH3COONa + H2O + CO2 Equation 2: NaHCO3 + HC2H3O2 [YIELDS]... show more I am trying to put lesson plans together for a basic, introductory chemistry class I am teaching this summer.

Equation 1:
CH3COOH + NaHCO3 ---> CH3COONa + H2O + CO2

Equation 2:
NaHCO3 + HC2H3O2 [YIELDS] NaC2H3O2 + H2O + CO2

Which one is right? Why is it right?
