Final answer:

16.8 moles

Step-by-step explanation:

To find the number of moles of KCl produced, we need to use the coefficients in the balanced equation. From the balanced equation: 2KBr + Cl2 -> 2KCl + Br2, we can see that for every mole of Cl2, 2 moles of KCl are produced.

So, if 8.4 moles of Cl2 completely react, then we can calculate the moles of KCl produced as follows:

8.4 moles Cl2 x (2 moles KCl / 1 mole Cl2) = 16.8 moles KCl

Therefore, 16.8 moles of KCl are produced when 8.4 moles of Cl2 gas completely react.
