organic chemistry – Is the ammonium substituent (-NH3+) really meta-directing in electrophilic substitution?

The Question : 25 people think this question is useful If we make a resonance structure for the anilinium ion, with positive charge at either the ortho or the para position, we get a pentavalent nitrogen, which is not possible. So, how is the $\ce{-NH3+}$ group meta-directing in electrophilic aromatic substitution reactions, e.g. in nitration

acid base – Why does lemon juice reduce the “fish” odor of sea food — specifically fish?

The Question : 26 people think this question is useful In studying about amines, I read that lemon juice is also used to wash fish because it reacts with the amines on and in the fish to convert the amines to its salt, just reducing the “fishy smell”. I was thinking that it must be
