Answer:
Noun- Thomas, Students, mouth
Pronouns- His, Him
Explanation:
A noun is the name of a person, animal, place or thing.
A pronoun is word that can take the place of a noun in a sentence.
From the sentence:
Thomas would not stop talking with his mouth full, so the students got mad at him.
The nouns and pronouns are;
Noun - Thomas, Students, mouth
Pronoun - His, Him
Thomas is a noun because it is the name of a person.
Mouth is noun because it is the name of an organ in the body.
Students is a common noun because it names a particular group of people.
His and Him are both pronouns because they were used in the sentence to replace the noun, Thomas.
