When baking soda and vinegar react the surface bubbles. What does this most likely indicate?

Chemical reaction with release of carbon dioxide gas causing effervescence or foaming

- When baking soda (sodium bicarbonate) and vinegar (acetic acid) react, they undergo a chemical reaction to form sodium acetate, water, and carbon dioxide gas.

- The formation of carbon dioxide gas causes the mixture to bubble and foam.

The overall chemical equation for the reaction is:

NaHCO3(s) + CH3COOH(aq) → NaCH3COO(aq) + H2O(l) + CO2(g)

In this equation, NaHCO3 represents baking soda, CH3COOH represents vinegar, NaCH3COO represents sodium acetate, H2O represents water, and CO2 represents carbon dioxide gas.
