$C H_{3} C O O H$ $CH_3COOH$ and $C H_{3} C O O^{-}$ $CH_3COO^-$
$H_{2} O$ $H_2O$ and $H_{3} O^{+}$ $H_3O^+$

Explanation:

So

the $C H_{3} C O O H$ $CH_3COOH$ is a acid

the $C H_{3} C O O H$ $CH_3COOH$ lost the hydrogen on the end so its the acid by the Bronsted Lowry Definition of acids

the $C H_{3} C O O^{-}$ $CH_3COO^-$ is the conjugate base as in the reverse reaction, it would have to pick up $H^{+}$ $H^+$ to form acetic acid again

The $H_{2} O$ $H_2O$ is an base (on the left), as it accepts the hydrogen ion that the acetic acid lost
(on the right side, it should be a $H_{3} O^{+}$ $H_3O^+$ instead)
The $H_{3} O^{+}$ $H_3O^+$ is a conjugate acid, as it would have to lose the $H^{+}$ $H^+$ to revert to $H_{2} O$ $H_2O$
