Question

Làm phương trình hóa học P→P2O5→H3PO4→Na3PO4→Zn3(PO4)2→Cu3(PO4)2

Answer 1

4P +5O2→2P2O5

P2O5+3H2O→2H3PO4

H3PO4+3NaOH→Na3PO4+3H2O

2Na3PO4+ 3ZnCl2→Zn3(PO4)2+6NaCl

Zn3(PO4)2+3CuCl2→Cu3(PO4)2+3ZnCl2

Chúc bạn học tốt

Answer 2

4P+5O2--->2P2O5

P2O5+3H2O--->2H3PO4

H3PO4+NaOH--->Na3PO4+3H2O

2Na3PO4+3ZnCl2--->Zn3(PO4)2+6NaCl

Zn3(PO4)2+3CuCl2--->3ZnCl2+Cu3(PO4)2

Answer 3

4P + 5O₂ --> 2P₂O₅

P₂O₅ + 3H₂O ---> 2H₃PO₄

H₃PO₄ + 3NaOH ---> Na₃PO₄ + 3H₂O

2Na₃PO₄ + 3ZnCl₂ --> Zn₃(PO₄)₂ + 6NaCl

Zn₃(PO₄)₂ + 3CuCl₂ ---> Cu₃(PO₄)₂ + 3ZnCl₂
