Question

Составьте уравнения реакций Ca3(PO4)2->P->P2O5->H3PO4->Na3PO4 + + + Mg3(PO4)2 Zn3(PO4)2 Ag3PO4

Answer 1

Ca3(PO4)2+3SiO2+5C=3CaSiO3+5CO+2P
4P+5O2=2P2O5
P2O5+3H2O=2H3PO4
3Na2O+2H3PO4=2Na3PO4+3H2O
2Na3PO4+3MgCl2=Mg3(PO4)2+6NaCl
2Na3PO4+3ZnCl2=6NaCl+Zn3(PO4)2
Na3PO4+3AgNO3=Ag3PO4+3NaNO3
Если я правильно поняла твои +

Answer 2

Chemical Reactions Equations

The chemical reactions for the given compounds are as follows:

1. Ca3(PO4)2 - Decomposes to form P, then further reacts to form P2O5, and finally forms H3PO4 and Na3PO4.

2. Mg3(PO4)2, Zn3(PO4)2, Ag3PO4 - The given compounds are not involved in the provided search results.

Equations

The equations for the reactions involving Ca3(PO4)2 are as follows:

1. Decomposition of Ca3(PO4)2 to form P: ``` Ca3(PO4)2 → 3Ca + 2P ```

2. Formation of P2O5 from P: ``` 4P + 5O2 → 2P2O5 ```

3. Formation of H3PO4 from P2O5: ``` P2O5 + 3H2O → 2H3PO4 ```

4. Formation of Na3PO4 from H3PO4: ``` H3PO4 + 3NaOH → Na3PO4 + 3H2O ```

Unfortunately, the search results did not provide relevant information for the reactions involving Mg3(PO4)2, Zn3(PO4)2, Ag3PO4. Therefore, I'm unable to provide the equations for these compounds based on the given search results.
