Instead of me going through and simply giving you the answers, tell me what you don't understand about these two questions.
I do not understand how to determine if the substance is an bronsted acid or base
If the substance can donate a proton, it is a Bronsted acid. If it can accept a proton, it is a Bronsted base.
examples:
Bronsted acid. HCl or NH4^+
HCl + H2O ==> H3O^+ + Cl^-
NH4^+ + H2O ==> H3O^+ + NH3
Bronsted base. NH3 or CO3^-2
NH3 + HOH ==> NH4^+ + OH^-
CO3^-2 + HOH ==> HCO3^- + OH^-
