How many moles of Mg(OH)2 will react with 2.5 mol HCI?
bekas [8.4K]

Answer:

1.25mole of Mg(OH)₂

Explanation:

The reaction is between Mg(OH)₂ and HCl, this is a neutralization reaction between an acid and a base.

The balanced reaction equation is given above.

           2 mole of HCl reacts with 1 mole of Mg(OH)₂

So,       2.5mole of HCl will react with \frac{2.5}{2}  = 1.25mole of Mg(OH)₂

The number of moles of Mg(OH)₂ is given as 1.25mol
