Question

P->P2O5->H3PO4->K3PO4

Answer 1

1)4P+5O2>2P2O5
2)P2O5+3H2O>2H3PO4
3)2H3PO4+6K>2K3PO4+3H2

Answer 2

The sequence you provided represents a series of chemical reactions involving different compounds of phosphorus. Here's a breakdown of each step:

1. P: This represents elemental phosphorus, which is a nonmetallic chemical element with the symbol P on the periodic table.

2. P2O5: This is diphosphorus pentoxide, a compound formed by the combination of two atoms of phosphorus (P) and five atoms of oxygen (O). It is an oxide of phosphorus.

3. H3PO4: This represents phosphoric acid, which is formed when diphosphorus pentoxide (P2O5) reacts with water (H2O). The reaction can be represented as follows: P2O5 + 3H2O → 2H3PO4

4. K3PO4: This represents potassium phosphate, which is formed when phosphoric acid (H3PO4) reacts with potassium hydroxide (KOH). The reaction can be represented as follows: 3H3PO4 + 3KOH → K3PO4 + 3H2O

In summary, the sequence you provided represents the conversion of elemental phosphorus (P) to diphosphorus pentoxide (P2O5), then to phosphoric acid (H3PO4), and finally to potassium phosphate (K3PO4). Each step involves specific reactions and compounds in the pathway.
