Some antacids contain aluminum hydroxide [Al(OH)3]. This compound reacts with excess hydrochloric acid (HCl) in the stomach to neutralize it. If the products of this reaction are water and aluminum chloride, what is the balanced chemical equation for this reaction?

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

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
