If 3.56 moles of hci reacts with excess mg(oh)2. how many miles of mgcl2 will be produced, and how many moles of h2o are produced?

 H₂O = 3.56 moles

 MgCl₂ = 1.78 moles

Explanation:

Given data:

Moles of HCl = 3.56 mol

Moles of water produced = ?

Moles of MgCl₂ produced = ?

Solution:

Chemical equation:

2HCl + Mg(OH)₂   →  MgCl₂ + 2H₂O

Now we will compare the moles of HCl with water and magnesium chloride.

                         HCl       :        MgCl₂

                            2        :           1

                           3.56    :          1/2×3.56 = 1.78 mol

                         HCl       :          H₂O

                            2        :           2

                           3.56    :          3.56 mol

the answer to this question is 3.
