Sulfur and fluorine react to form sulfur hexafluoride according to the reaction shown here. How many mol of F2 are required to react completely with 2.25 mol of S? S(s)+3F2(g) => SF6(g)

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Suppose a lab group reports a ppercent yield of sand of 105. is it really possible to collect more sand than was originally represented? what is the possible explanation for the extra product?
