Hydroxyapatite, ca5(po4)3(oh), is the main mineral component of dental enamel, dentin, and bone, and thus has many medical uses. coating it on metallic implants (such as titanium alloys and stainless steels) the body accept the implant. in the form of powder and beads, it is used to fill bone voids, which encourages natural bone to grow into the void. hydroxyapatite is prepared by adding aqueous phosphoric acid to a dilute slurry of calcium hydroxide. (a) write a balanced equation for this preparation. (b) what mass of hydroxyapatite could form from 100. g of 85% phosphoric acid and 100. g of calcium hydroxide?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
