N aqueous solutions, HF is a much weaker acid than HCl. However, when combined with Lewis acids, fluorinated systems make much stronger superacids than chlorinated ones. Which of the following best accounts for this phenomenon?
A. Aqueous, solvated F- ions are more stable in aqueous media than Cl- ions.
B. F- forms very stable complex anions through strong bonding to Lewis acids.
C. The basicity of the Cl- ion hinders its inclusion in complex anions.
D. The larger size of the Cl- anion sterically prevents its inclusion in the complex anion with a metal like Sb.

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
