1 Answer

Answer :

(1} Tricalcium phosphate Explanation: Our bones and teeth are generally made up of Tricalcium Phosphate. Tricalcium phosphate is a calcium salt of phosphoric acid with the chemical formula Ca004)2. It is also known as tribasic calcium phosphate and bone phosphate of lime, BPL. Calcium phosphate is one of the main combustion products of bone.
