Question

H2O2->O2->P2O5->H3PO4 + Ca3(po4)2

Answer 1

1) H2O2 → H2 + O2

2) 5O2 + 4P → 2P2O5

3) P2O5 + 3H2O → 2H3PO4

4) Ca3(PO4)2 + 2H2O2 = 2CaO2 + Ca(H2PO4)2

Answer 2

It looks like you've provided a chemical reaction sequence:

1. Hydrogen Peroxide (H2O2) decomposes to form Oxygen (O2).
2. Oxygen (O2) reacts with Phosphorus Pentoxide (P2O5).
3. The reaction between Oxygen (O2) and Phosphorus Pentoxide (P2O5) yields Phosphoric Acid (H3PO4).
4. Phosphoric Acid (H3PO4) reacts with Calcium Phosphate (Ca3(PO4)2) to produce a product.

The reaction steps you've provided are somewhat simplified and not entirely accurate. If you could provide more specific details about the reaction conditions, reactant quantities, and any other relevant information, I could help you better understand the reaction and provide a more accurate description.
