Write down the reaction equations with which you can carry out the chains of transformations phosphorus-phosphorus

Write down the reaction equations with which you can carry out the chains of transformations phosphorus-phosphorus oxide (5) -phosphoric acid-potassium phosphate-orthophosphoric acid-sodium phosphate

4P + 5O2 = 2P2O5 .
P2O5 + 3H2O = 2H3PO4 .
H3PO4 + 3KOH = K3PO4 + 3H2O.
3CaCl2 + 2K3PO4 = Ca3(PO4)2 + 6KCl .
Ca3PO42 + 3H2SO4 = 3CaSO4 + 2H3PO4 .
