1. Balanced Chemical Equation:

The balanced chemical equation is:

MgCl₂ + 2KOH → Mg(OH)₂ + 2KCl

2. Mole Ratio:

The equation shows that 1 mole of MgCl₂ reacts with 2 moles of KOH.

3. Calculate Moles of KOH Needed:

Since you have 6 moles of MgCl₂, you'll need 6 moles * 2 = 12 moles of KOH to react completely.

4. Determine the Limiting Reagent:

* If you have less than 12 moles of KOH: KOH is the limiting reagent, as you don't have enough to react with all of the MgCl₂.

* If you have 12 moles or more of KOH: MgCl₂ is the limiting reagent because you have enough KOH to react with all of the MgCl₂.

Conclusion:

You need to provide the amount of KOH (in moles) to determine the limiting reagent.
