    The answer to your question is Al (OH) ₃ + 3 HCl ⇒ AlCl₃ + 3H₂O

    Explanation:

    Data

    Reactants

    Aluminum hydroxide [Al (OH) ₃]

    Hydrochloric acid (HCl)

    Products

    Water (H₂O)

    Aluminum chloride [AlCl₃]

    Chemical reaction

    Al (OH) ₃ + HCl ⇒ AlCl₃ + H₂O

    Reactants Elements Products

    1 Al 1

    1 Cl 3

    4 H 2

    3 O 1

    This reaction is unbalanced

    Al (OH) ₃ + 3 HCl ⇒ AlCl₃ + 3H₂O

    Reactants Elements Products

    1 Al 1

    3 Cl 3

    6 H 6

    3 O 3

    Now, the reaction is balanced
