Write the reaction equation: P → P2O5 → H3PO4 → Ca3 (PO4) 2 → CaO

1) 4Р + 5О2 = 2Р2О5 (when phosphorus interacts with oxygen, phosphorus oxide is formed);
2) P2O5 + 3H2O = 2H3PO4 (when phosphorus oxide interacts with water, phosphoric acid is formed);
3) 2H3PO4 + 3Ca = Ca3 (PO4) 2 + 3H2 (when phosphoric acid interacts with calcium, calcium phosphate and hydrogen are formed);
4) Ca3 (PO4) 2 = 3CaO + P2O5 (upon decomposition of calcium phosphate, calcium oxide and phosphorus oxide are formed).
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
