Answer:

3.

Explanation:

  • Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:

Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,

It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,

So, the coefficient of HCl is 3.
