The answer is C.
When baking soda and vinegar are mixed together, a chemical reaction occurs. This is a vigorous reaction. Baking soda is called sodium bicarbonate, and has the chemical formula ##”NaHCO”_3″## Vinegar is a very dilute solution of acetic acid with the formula ##”CH”_3″COOH”##.
The word equation for the overall reaction is:
Solid sodium bicarbonate reacts with aqueous acetic acid to produce aqueous sodium acetate (##”CH”_3″COONa”##), liquid water, and carbon dioxide gas.
The chemical equation for the overall reaction is:
##”NaHCO”_3(“s”)+”CH”_3″COOH(aq)”####rarr####”CH”_3″COONa(aq)”+”H”_2″O(l)”+”CO”_2(“g”)”##
