Let us write down the reaction equations for a given chain of compounds.

P2O5 -> H3PO4 -> Na3PO4 -> Ca3 (PO4) 2.

P2O5 + 3H20 = 2H3PO4.

Reaction refers to the reactions of a compound to form phosphoric acid.

H3PO4 + 3NaOH = Na3PO4 + 3H2O.

Reaction refers to an exchange or neutralization reaction. With the formation of water and sodium phosphate.

Na3PO4 + 3Ca (OH) 2 = Ca3 (PO4) 2 + 3NaOH.

Reaction refers to exchange reactions. This reaction produces calcium phosphate and sodium hydroxide.
