Answer to Question #259297 in General Chemistry for anna

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?

Answer 1

Molar mass of CaF₂=78.07g/mol

10/78.07= 0.128

Molar mass of H2SO4= 98.079

15/98.079=0.15

The limiting reactant is CaF₂
