Question

Р-->Р2О5-->НРО3-->Н3РО4-->Na3PO4​

Answer 1

Ответ:

1. 4P + 5O2 = 2P2O5

2. P2O5 + H2O =2HPO3

3. HPO3 + H2O = H3PO4

4. H3PO4 + 3NaCl = Na3PO4 + 3HCl

Answer 2

1) 4P+5O2=2P2O5

2) P2O5+2HNO3=2HPO3+N2O5

3) HPO3+H2O=H3PO4

4) H3PO4+3NaOH=Na3PO4+3H2O

Answer 3

The series of reactions you've provided involves the conversion of phosphorus (P) into sodium phosphate (Na3PO4). Here's a breakdown of each step:

1. P --> P2O5: Phosphorus reacts with oxygen to form phosphorus pentoxide (P2O5).

2. P2O5 --> HPO3: Phosphorus pentoxide reacts with water to form phosphoric acid (HPO3), also known as phosphorous acid.

3. HPO3 --> H3PO4: Phosphorous acid undergoes further reaction with water to produce phosphoric acid (H3PO4).

4. H3PO4 --> Na3PO4: Phosphoric acid reacts with sodium hydroxide (NaOH) to form sodium phosphate (Na3PO4).

So, the overall reaction can be summarized as:

P + 5O2 + 6H2O + 6NaOH → 2Na3PO4 + 6H2O

Please note that the actual reaction conditions, stoichiometry, and reaction mechanisms may vary depending on the specific experimental setup and requirements.
