If mixing baking soda, (NaHCO3) with vinegar (CH3COOH) to generate carbonic acid (H2CO3), which breaks up into water and carbon dioxide gas) and sodium acetate (NaCH3COO),

would the equation be:
NaHCO3 + CH3COOH yields H2CO3 + NaCH3COO

Your face

Answer would be....

NaCH3COO + CO2 + H2O

Yes, the equation for the reaction between baking soda (NaHCO3) and vinegar (CH3COOH) would be:

NaHCO3 + CH3COOH → H2CO3 + NaCH3COO

This reaction produces carbonic acid (H2CO3), which then breaks up into water (H2O) and carbon dioxide gas (CO2). The sodium acetate (NaCH3COO) is also produced in the process.
