Introduction to Acid-Base Reactions Practice Test

In the reaction $\mathrm{C_2H_5NH_2(aq) + H_2O(l) \rightarrow C_2H_5NH_3^+(aq) + OH^-(aq)}$, which species is the conjugate acid of $\mathrm{C_2H_5NH_2}$?

For the reaction $\mathrm{HSO_4^-(aq) + H_2O(l) \rightarrow SO_4^{2-}(aq) + H_3O^+(aq)}$, which species is the Brønsted–Lowry acid?
