Make an equation for the transformation: P2O5-Mg3 (PO4); Mg-MgO-MgSO4. name the reaction products

1 chain:

1) 4P + 5O2 = 2P2O5 (when phosphorus interacts with oxygen, phosphorus (V) oxide is formed);

2) P2O5 + 3Mg (OH) 2 = Mg3 (PO4) 2 + 3H2O (when phosphorus (V) oxide interacts with magnesium hydroxide, magnesium orthophosphate and water are formed).

2 chain:

1) 2Mg + O2 = 2MgO (when magnesium interacts with oxygen, magnesium oxide is formed);

2) MgO + H2SO4 = MgSO4 + H2O (when magnesium oxide interacts with sulfuric acid, magnesium sulfate and water are formed).
