Question

:P>P2O5 >H3PO4>Na3PO4+Mg3(PO4)2.​

Answer 1

Ответ:

Объяснение:

4P +5 O2 = 2P2O5

P2O5 + 3H2O= 2H3PO4

2H3PO4 + 3Na2O = 2Na3PO4 + 3H2O

2Na3PO4 + 3MgCl2 = Mg3(PO4)2 + 6NaCl

Answer 2

The expression you provided represents a chemical reaction involving different compounds and their transformation. Let's break it down step by step:

1. :P2O5: This represents diphosphorus pentoxide, which is a chemical compound composed of two phosphorus atoms and five oxygen atoms.

2. H3PO4: This symbol ">" indicates that diphosphorus pentoxide reacts with something to produce another compound. In this case, it reacts with water (H2O) to form phosphoric acid (H3PO4).

3. Na3PO4: This indicates that phosphoric acid reacts with sodium hydroxide (NaOH), resulting in the formation of sodium phosphate (Na3PO4) and water (H2O).

4. +Mg3(PO4)2: The "+" symbol denotes that sodium phosphate reacts with another compound. In this case, it reacts with magnesium chloride (MgCl2) to form magnesium phosphate (Mg3(PO4)2) and sodium chloride (NaCl).

To summarize the reaction sequence: Diphosphorus pentoxide (P2O5) reacts with water (H2O) to form phosphoric acid (H3PO4). Then, phosphoric acid reacts with sodium hydroxide (NaOH) to produce sodium phosphate (Na3PO4) and water (H2O). Finally, sodium phosphate reacts with magnesium chloride (MgCl2) to yield magnesium phosphate (Mg3(PO4)2) and sodium chloride (NaCl).
