Solution of the task:
1. Interaction of phosphorus with oxygen with the formation of phosphorus oxide (5): 4Р + 5О2 = 2Р2О5;
2. interaction of phosphorus oxide (5) with calcium hydroxide with the formation of calcium orthophosphate and water: P2O5 + 3Ca (OH) 2 = Ca3 (PO4) 2 + 3H2O;
3. Interaction of calcium oxide with phosphorus oxide (5) with the formation of calcium orthophosphate: 3CaO + P2O5 = Ca3 (PO4) 2;
4. Interaction of calcium with oxygen with the formation of calcium oxide: 2Ca + O2 = 2CaO.
