Question

The toxic gas hydrogen fluoride, HF, is produced from the double displacement reaction of calcium fluoride, CaF₂, and concentrated sulfuric acid, H₂SO₄. Starting with 10.0g of CaF₂ and 15.0g H₂SO₄, the balanced chemical equation is CaF₂ + H₂SO₄ → 2 HF + CaSO₄. Which is the limiting reactant? Which is the excess reactant? What is the theoretical yield? How much of the excess reagent is not consumed in the reaction?

Answer 1

Limiting reagent =CaF2

Excess reactant=H₂SO₄
