No. A carboxyl group is made up off carbon, oxygen, and hydrogen.
No, only fatty acids contain carboxyl groups.
a nitrogen atom in an amino group and a carbon atom in a carboxyl group
The contain a carboxyl (COOH) group at one end of the molecule. At physiological pH (approx. 7.4) they are ionised to COO-, proton donors are acidic. However they also contain a basic amino group (NH2) and the hydrogen lost from the carboxyl group is transferred to this nitrogen forming NH3+. These charges cancel each other out and give them an overall neutral charge at this pH.
two examples are carboxyl and hydroxyl examples are vinegar for carboxyl and phenol for hydroxyl there are many others
Carbon (from the carboxyl group, not the alpha carbon) and Nitrogen (from the amino group).
Both carbohydrates and lipids contain a carboxyl group. They differ in that carbohydrates are formed between a carboxyl and an aldehyde group whereas a lipid is formed between a carboxyl and a hydroxyl group. Amino acids also contain a carboxyl group, though it forms a peptide bond with an amino group.
This wording of this question sounds like you may be confused. In the term "carboxyl group", group refers to a specific group of atoms (COOH), not to a group of similar types of compounds. Since hydrocarbons by definition contain only carbon and hydrogen, a hydrocarbon cannot contain a carboxyl group.
Yes

Yes.

The two amino acids aspartate and glutamate each contain two carboxyl groups.
