Answer 2

The chemical reactions you've listed involve the transformation of compounds. Let's go through each reaction step by step:

1. H2SiO3 → H2O: This reaction represents the decomposition of orthosilicic acid (H2SiO3) into water (H2O).

2. H2O → Ca(OH)2: This reaction involves the reaction of water (H2O) with calcium oxide (CaO) to produce calcium hydroxide (Ca(OH)2).

3. Ca(OH)2 → CaO: This reaction represents the thermal decomposition of calcium hydroxide (Ca(OH)2) into calcium oxide (CaO) and water (H2O).

4. CaO → Ca3(PO4)2: This reaction involves the reaction of calcium oxide (CaO) with phosphoric acid (H3PO4) to produce calcium phosphate (Ca3(PO4)2) and water (H2O).

5. Ca3(PO4)2 → P2O5: This reaction represents the thermal decomposition of calcium phosphate (Ca3(PO4)2) into diphosphorus pentoxide (P2O5) and calcium oxide (CaO).

Overall, these reactions involve the transformation of orthosilicic acid into diphosphorus pentoxide via a series of intermediate compounds.
