Question

P_P2O5_H3PO4_Ca(PO4)2

Answer 1

4P+5O2=2P2O5

P2O5+3H2O=2H3PO4

2H3PO4+3CaO=Ca3(PO4)2+3H2O

Answer 2

The chemical formula you provided contains four chemical compounds: P2O5, H3PO4, and Ca(PO4)2. Let's break down each of them:

1. P2O5: P2O5 is the chemical formula for diphosphorus pentoxide. It is a white, crystalline solid and is an anhydride of phosphoric acid (H3PO4). When P2O5 reacts with water, it forms phosphoric acid.

2. H3PO4: H3PO4 is the chemical formula for phosphoric acid. It is a weak acid and is commonly used in various industrial processes, as well as in the production of fertilizers and food additives.

3. Ca(PO4)2: Ca(PO4)2 is the chemical formula for calcium phosphate, which is a family of compounds that contain calcium ions (Ca2+) and phosphate ions (PO43-). It is an important mineral in the human body and is essential for bone formation and other biological processes.
