Answer
Hydrobromic acid:
HBr
Bromic Acid:
HBr$O_{3}$
Work Step by Step
Hydrobromic acid:
The naming system for acids, whenever the word hydro is first in the name of the acid, there will only be one hydrogen and one dissociating ion.
Bromic acid:
Bromic acid comes from the bromate ion, Br$O_{3}$, the way the naming systems work for acids is ate to ic, ite to ous. Since bromate ends in (ate) the ending will be changed bromic and the word acid will be added to the end.
