In the article Tooth Decay: A Delicate Balance, we learn that tooth decay occurs when the equilibrium between mineralization and demineralization becomes unsteady, according to this equation:
Ca5(PO4)3(OH) ↔ 5 Ca2+ + 3 PO43- + OH-
When a tooth decays, which way do we expect the equilibrium to lie? What does that tell us about the magnitude of K for this reaction?

To aid in the prevention of tooth decay, it is recommend that
drinking water contain 0.700 ppm fluoride (F-).
(a) How many grams of F- must be added to a cylindrical water
reservior having a diameter of 4.23 x 102 m and a depth
of 18.92 m?
(b) How many grams of sodium fluoride contain this much
fluoride?
Thanks for the help!

To aid in the prevention of tooth decay, it is recommended that
drinking water contain 1.10 ppm fluoride (F–). (a) How many grams
of F– must be added to a cylindrical water reservoir having a
diameter of 4.03 × 102 m and a depth of 55.43 m? (b) How many grams
of sodium fluoride, NaF, contain this much fluoride?

One form of nuclear radiation, beta decay, occurs when a neutron
changes into a proton, an electron and a neutral particle called a
neutrino. When this change happens to a neutron within the nucleus
of an atom, the proton remains behind in the nucleus while the
electron and neutrino are ejected from the nucleus. The ejected
electron is called a beta particle. One nucleus that exhibits beta
decay is the isotope of hydrogen 3H, called tritium,
whose nucleus consists of...

"Tongue Piercing May Speed Tooth Loss, Researchers Say" is the
headline of an article. The article describes a study of 51 young
adults with pierced tongues. The researchers found receding gums,
which can lead to tooth loss, in 17 of the participants.
(a) Construct a 95% confidence interval for the proportion of
young adults with pierced tongues who have receding gums. (Round
your answers to three decimal places.)
