the firsts step is to work out the products formed

yeah that's where the trouble is.  I know how to find the coefficients, but these reactions don't look like any ones we've studied so far (acid-base, redox, precipitation, complexation)

Hydroxylapatite + Acetic acid

anonymous · Answer

the H+ will be removed from CH3COOH, but will it bond with the OH- from the other reactant?  And what will happen with calcium, phosphate, and acetate?  Which two will bond together?
