Make up the reaction equation: 1.P- P2O5 H3PO4- Mg3 (PO4) 2 / Cu3 (PO4) 2- CuO

Make up the reaction equation: 1.P- P2O5 H3PO4- Mg3 (PO4) 2 / Cu3 (PO4) 2- CuO 2.C- CO2- Na2CO3 + HCl- X / + HCl- Z

1) 4P + 5O2 → 2P2O5 – compound reaction;

P2O5 + 3H2O → 2H3PO4 – compound reaction;

2H3PO4 + 3MgCl2 → Mg3 (PO4) 2 + 6HCl – exchange reaction;

Mg3 (PO4) 2 + 3Cu (OH) 2 → 3Mg (OH) 2 + Cu3 (PO4) 2 – exchange reaction;

Сu3 (PO4) 2 → 3CuO + P2O5 – decomposition reaction.

2) C + O2 → CO2 – compound reaction;

CO2 + Na2O → Na2CO3 – compound reaction;

Na2CO3 + HCl → NaCl + H2O + CO2 – exchange reaction.
