Осуществите превращения P-P2O5- H3PO4-Na-NaO-NaOH-Ca3(PO4)2 ​

4 P + 5 O2 = 2 P2O5

P2O5 + 3 H2O = 2 H3PO4

3 NaOH + H3PO4 = Na3PO4 + 3 H2O

2 Na3PO4 + 3 CaCl2 = Ca3(PO4)2 ↓ + 6 NaCl

Zn + 2 HCl = ZnCl2 + H2 ↑

ZnCl2 + 2 CsOH = Zn(OH)2 ↓ + 2 CsCl

Zn(OH)2 t° = ZnO + H2O

ZnO + 2 HNO3 = Zn(NO3)2 + H2O

4 Al + 3 O2 = 2 Al2O3

Al2O3 + 6 HCl = 2 AlCl3 + 3 H2O

AlCl3 + 3 KOH = Al(OH)3 ↓ + 3 KCl

2 Al(OH)3 t° = Al2O3 + 3 H2O
