Sodium fluoride reacts with hydroxyapatite to give fluorapatite according to the chemical reaction:
2naf + ca10(po4)6(oh)2 → ca10(po4)6f2 + 2naoh
i. name each ion in fluorapatite.
ii. indicate the charge on each ion in fluorapatite.
iii. show that the molecular formula for fluorapatite represents a neutral compound

We are given the balanced equation 2NaF + Ca10(PO4)6(OH)2 → Ca10(PO4)6F2 + 2NaOH. The fluorapatite is the product together with sodium hydroxide. The ions involved are (PO4) 3-, Ca 2+ and F-. We add the charges and check if the sum is zero, 2*10+-3*6+-1*2 =0. the zero sum tells that the compound has zero charge or neutral

Afraidsugar lol it’s the third one

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
