Write the equation for obtaining calcium phosphate by the reaction of a compound.

The reaction of the compound is: A + B = AB, in this case A is calcium oxide (basic) CaO, B is phosphorus (V) oxide (acidic) P2O5, the AB salt is formed – calcium phosphate Ca3 (PO4) 2
3CaO + P2O5 = Ca3 (PO4) 2
The reaction takes place on contact of two powdered oxides.
