a. It's a strong acid dissociation.
We can notice that because we have a simple arrow (=>), and it indicates that there is no ionic equilibrium. It means it is all dissociated.
b. Something important here is that we have many definitions for acid and base, I mean we have theories like Arrhenius, Brønsted-Lowry, and Lewis.
Product side: H+ + Cl-
Cl- Conjugate base
H+
