2.Given the reactant side of the total ionic equation for the neutralization reaction of ammonium hydroxide (NH4OH) with hydrochloric acid (HCl), write the total ionic equation (also known as the complete ionic equation) by entering both the reactant and the product species, separated by the reaction arrow.

NH4+(aq)+OH−(aq)+H+(aq)+Cl−(aq)→ ?

Be sure to include the charges on the ionic species and the physical state of all the reactant and product species.

Express your answer as a chemical equation.
