Answer

a. $HClO_{4(aq)}\Rightarrow H^+_{(aq)}+ClO_{4(aq)}^-$ b. $CH_3CH_2CO_2H_{(aq)}\Rightarrow H^+_{(aq)}+CH_3CH_2CO_{2(aq)}^-$ c. $NH_{4(aq)}^+\Rightarrow H^+_{(aq)}+NH_{3(aq)}$

Work Step by Step

The dissociation of an acid is as follows: $HA\Rightarrow H^+ + A^-$ Therefore, because all three substances are acids the reactions are: $HClO_{4(aq)}\Rightarrow H^+_{(aq)}+ClO_{4(aq)}^-$ $CH_3CH_2CO_2H_{(aq)}\Rightarrow H^+_{(aq)}+CH_3CH_2CO_{2(aq)}^-$ $NH_{4(aq)}^+\Rightarrow H^+_{(aq)}+NH_{3(aq)}$
