Question

Склади рiвняння реакцiй, за допомогою яких можна здiйснити такі перетворення: P→ P2O5 →H2PO4 → Na2PO4дуже терміново!!!!​

Answer 1

Ответ:

4P + 5O2 = 2P2O5

P2O5 + 3H2O = 2H3PO4

H3PO4 + NaOH = NaH2PO4 + H2O

NaH2PO4 + NaOH = Na2HPO4 + H2O

Na2HPO4 + NaOH = Na3PO4 + H2O

Na3PO4 + 3AgF = 3NaF + Ag3PO4

Answer 2

Equations for the Given Transformations:

To carry out the given transformations: P → P2O5 → H2PO4 → Na2PO4, we can use the following equations:

1. P → P2O5: - The reaction between phosphorus (P) and oxygen (O2) forms diphosphorus pentoxide (P2O5). - The balanced equation for this reaction is: 4P + 5O2 → 2P2O5 [[1]].

2. P2O5 → H2PO4: - Diphosphorus pentoxide (P2O5) reacts with water (H2O) to form phosphoric acid (H3PO4). - The balanced equation for this reaction is: P2O5 + 3H2O → 2H3PO4 [[2]].

3. H2PO4 → Na2PO4: - Phosphoric acid (H3PO4) reacts with sodium hydroxide (NaOH) to form sodium phosphate (Na2PO4) and water (H2O). - The balanced equation for this reaction is: 2H3PO4 + 6NaOH → 2Na2PO4 + 6H2O [[3]].

Please note that these equations represent the balanced chemical reactions for the given transformations.
