Predict how each molecule or ion would act, in the Brønsted-Lowry sense, in aqueous solution by writing "acid," "base," "both," or "neither" on the line provided.

The question is incomplete. The molecules/ ions are:

Bicarbonate ion

N-methyl-3-phenyl-3-[4-(trifluoromethyl)phenoxy]propan-1-amine (Prozac)

Para aminobenzoic acid (PABA)

Trinitrotoluene

N-methylpyridinium ion

Bicarbonate ion- base

N-methyl-3-phenyl-3-[4-(trifluoromethyl)phenoxy]propan-1-amine (Prozac)-acid

Para aminobenzoic acid (PABA)- both

Trinitrotoluene- acid

N-methylpyridinium ion- neither

Explanation:

In the Brønsted-Lowry sense, an acid is any substance that donates hydrogen ion while a base is any substance that accepts hydrogen ions. Looking at the compounds given above, acidity depends on the molecule's ability to accept or donate protons hence the classification given in the answer.

"the periodic table is arranged in order of atomic number."
