Answer: CaCl2 + 2HF > CaF2 + 2HCl
Explanation: The chemical equation written above, is that of Calcium Chloride + Hydrogen Fluoride > Fluorite + Hydrogen Chloride. You were almost correct in the way you had the equation balanced, but there were a couple of readjustments that needed to be made. Your equation should have been written as CaCl2 + 2HF > CaF2 + 2HCl.
It needed to be this way, because you had 2 fluorine in the second half of the equation and only one in the first half (HF) and if you changed in to 2 fluorine, then you'd also be adding an additional hydrogen to the first half and so to make sure that your inputs equalled your outputs, you also needed another hydrogen in the second half.
