Tooth enamel is composed of hydroxyapatite, Ca5(PO4)3OH (Ksp = 6.8 10-37). Many water treatment plants add F- ion to drinking water, which reacts with Ca5(PO4)3OH to form the more tooth decay-resistant fluorapatite, Ca5(PO4)3F (Ksp = 1.0 10-60). Fluoridated water has resulted in a dramatic decrease in the number of cavities among children. Calculate the solubility of Ca5(PO4)3F in water.

The diagrams to the right show the distribution and arrangement of gas particles in two different containers. according to kinetic-molecular theory, which of the following statements is true? check all that apply. if the temperatures of both containers are equal, container a has greater pressure than container b. if the volume of container a decreased, its pressure would decrease. if the pressure in both containers is equal, container a has a lower temperature than container b.
