Answer:
F
Step-by-step explanation:
because since the Hydrogens are unbalanced you would multiply KOH by 2 and H20 by 2 to give 4 hydrogens on both sides. But by multiplying KOH by 2 there are now 2 potassiums on the right side and one potassium on the left. so on the left multiply K by 2 and your equation is balanced.
