Question

P P205 H3 PO4 Na3 PO4​

Answer 1

1) 4P + 5O2 -> 2P2O5
2) P2O5 + 3H2O -> 2H3PO4
3) H3PO4 + 3NaOH-> Na3PO4 + 3H2O

Answer 2

4P + 5O2 = 2P2O5

3H2O + P2O5 = 2H3PO4

6Na + 2H3PO4 = 2Na3PO4 + 3H2

Answer 3

It seems like you've provided a list of chemical compounds: P2O5, H3PO4, and Na3PO4. These are all phosphorus-containing compounds. Here's some information about each of them:

1. P2O5 (Diphosphorus Pentoxide):

   • Chemical Formula: P2O5
   • Common Names: Diphosphorus pentoxide, phosphorus(V) oxide, phosphoric anhydride
   • Description: P2O5 is a white, crystalline solid that is highly reactive with water. It is a powerful dehydrating agent and is often used in chemical reactions to remove water molecules.

2. H3PO4 (Phosphoric Acid):

   • Chemical Formula: H3PO4
   • Common Names: Phosphoric acid
   • Description: Phosphoric acid is a mineral acid with a syrupy consistency. It is widely used in various industries, including food and beverages, as a pH regulator and acidulant. It has three acidic hydrogen atoms.

3. Na3PO4 (Sodium Phosphate):

   • Chemical Formula: Na3PO4
   • Common Names: Sodium phosphate
   • Description: Sodium phosphate is a salt that contains sodium ions (Na+) and phosphate ions (PO4^3-). There are different forms of sodium phosphate, including trisodium phosphate (Na3PO4), disodium phosphate (Na2HPO4), and monosodium phosphate (NaH2PO4). They are used in various applications, including food processing and as a cleaning agent.
