Question

PLEASE ANSWER!!! NEED HELP!!!

In the reaction MgC12 + 2KOH Mg(OH)2 + 2KCl, if 1 mole MgC12 is added to
3 moles KOH, what is the limiting reagent?
KCI
Mg(OH)2
KOH
MgCl2

Answer 1

For 1 mole of MgCl2, it would require 2 moles of KOH. ( 1 : 2 mole ratio)

Since you have 3 moles of KOH, it is in excess, and MgCl2 is the limiting reactant.
