Answer:

Two electrons are transferred in this reaction.

Explanation:

The question cites the equation is unbalanced.

#Cl_2(aq) + 2Kl(aq) to 2KCl(aq) + I_2(aq)#

The oxidation state of pure elements (e.g. chlorine and iodine) are 0. We may deduce that since potassium has a #1+# charge:

#Cl_2# is reduced to #1-# charge, and concomitantly #I^-# is oxidized to #0# charge from #1-# charge.
