The ksp of beryllium hydroxide, be(oh)2, is 6.92 × 10-22. calculate the solubility of this compound in g/l.

Solubility product constants are values to describe the saturation of ionic compounds with low solubility. It is represented by Ksp and is the product of the concentration of the dissolved ions to the power of its stoichiometric coefficient. We do as follows:

Be(OH)2 = Be2+ + 2OH-

Ksp = [Be2+][OH-]^2
6.92 × 10^-22 = x(2x)^2
x = 5.57x10^-8 mol /L

[Be(OH)2] = x = 5.57x10^-8 mol /L = 2.397x10^-6 g/L

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
