`A)` `"NaHCO"_3(aq) + "CH"_3"COOH"(l) -> "CH"_3"COONa"(aq) + "H"_2"O"(g) + "CO"_2(l)`
`B)` `"NaHCO"_3(aq) + "CH"_3"COOH"(s) -> "CH"_3"COONa"(aq) + "H"_2"O"(l) + "CO"_2(g)`
`C)` `"NaHCO"_3(s) + "CH"_3"COOH"(aq) -> "CH"_3"COONa"(aq) + "H"_2"O"(l) + "CO"_2(g)`
`D)` `"NaHCO"_3(l) + "CH"_3"COOH"(aq) -> "CH"_3"COONa"(aq) + "H"_2"O"(g) + "CO"_2(l)`

Answer 1

The answer is C.

Explanation:

Sodium bicarbonate `"HCO"_3"`, also known as baking soda, is a solid at room temperature. Vinegar is a very dilute aqueous 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")"`
