First, write the dissociation reaction. We start with the acid and water (solvent) as the reactants. Then the products should be the conjugate base (1 less H) and H3O+ ( where the H went).  Take note of the charges. The conjugate base should gain a negative charge. All of the compounds except water (liquid) should be aqueous (aq) since they are dissolved in water.
