Calcium fluoride + sulfuric acid → Hydrogen fluoride + Calcium sulfate
calcium fluoride = CaF2
Sulfuric acid = H2SO4
hydrogen fluoride = HF
calcium sulfate = CaSO4
CaF2 + H2SO4 → HF + CaSO4
Balanced chemical reaction
CaF2 + H2SO4 → 2 HF + CaSO4
For nomenclature please refer the following link which will include formula writing also.
For writing equation, it depend upon the oxidation state of the element.
The above reaction is double displacement reaction.
Compounds with there oxidation states
CaF2 = Ca^+2, F^-1.
H2SO4 = 2H^+, SO4^2-
CaSO4 = Ca^+2, SO4^2-
HF = H^+, F^-.
Depending upon the oxidation state the shuffling of the element takes place.

The formula is CaF2 + H2SO4 ---> CaSO4 + 2HF
The products are hydrogen fluoride (HF) and Calcium sulfide (CaSO4) The equation is balance above.
Ca = 1
F = 2
H = 2
SO4 = 1
