Question

P205 → H3PO4 → Mg3(PO4)2 → MgSO4​

Answer 1

Ответ:

P2O5 + 3H2O = 2H3PO4

2H3PO4 + 3Mg = Mg3(PO4)2 + 3H2

Mg3(PO4)2 + 3Na2SO4 = 3MgSO4 + 2Na3PO4

Answer 2

It seems like you're describing a series of chemical reactions involving different compounds. Let's break down these reactions step by step:

1. P2O5 (Phosphorus Pentoxide) reacts with water (H2O) to form H3PO4 (Phosphoric Acid):

   P2O5 + 3 H2O → 2 H3PO4

2. H3PO4 (Phosphoric Acid) reacts with magnesium hydroxide (Mg(OH)2) to form magnesium phosphate (Mg3(PO4)2):

   2 H3PO4 + 3 Mg(OH)2 → Mg3(PO4)2 + 6 H2O

3. Mg3(PO4)2 (Magnesium Phosphate) can potentially react with sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4), but the balanced equation for this reaction would depend on the stoichiometry and conditions of the reaction:

   Mg3(PO4)2 + H2SO4 → MgSO4 + H3PO4

Please note that the actual reaction conditions and stoichiometry may vary depending on the specific experiment or situation. If you have a specific reaction condition or context in mind, please provide more details for a more accurate answer.
