The Balanced Chemical Equation:

MgCl₂ + 2KOH → Mg(OH)₂ + 2KCl

Stoichiometry:

* The coefficients in a balanced chemical equation represent the mole ratios of reactants and products.

* The coefficient in front of MgCl₂ is 1, and the coefficient in front of Mg(OH)₂ is also 1.

Answer:

Therefore, 1 mole of Mg(OH)₂ is produced for every 1 mole of MgCl₂.
