Write molecular and, where it takes place, ionic equations of reactions according to the scheme: P → P₂O₅ → H₃PO₄

Write molecular and, where it takes place, ionic equations of reactions according to the scheme:
P → P₂O₅ → H₃PO₄ → Na₃PO₄.

4P + 5O₂ = 2P₂O₅ addition; P₂O₅ + 3H₂O = 2H₃PO₄ addition; 2H₃PO₄ + 6Na = 2Na₃PO₄ + 3H₂ substitutions

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
