Question

P->P2O5->Na3PO4->NaOH->NaCl->Na​

Answer 1

1) 2P+5O2=2P2O5

2)6NaOH+P2O5=2Na3PO4+3H2O

3)2Na3PO4+3Ba(OH)2=Ba3(PO4)2+6NaOH

4)NaOH+HCl=NaCl+H2O

5)NaCl+Li=LiCl+Na

или же расплавом 2NaCl=2Na+Cl2

Answer 2

It looks like you have provided a sequence of chemical reactions involving various compounds containing the element sodium (Na). Let's break down each step of the reaction:

1. P: This could represent a reactant, but without more information, it's unclear what specific compound or element it represents.

2. P2O5: This is diphosphorus pentoxide, a compound containing two atoms of phosphorus and five atoms of oxygen.

3. Na3PO4: This is sodium phosphate, a compound containing three sodium atoms (Na) and one phosphate group (PO4).

4. NaOH: This is sodium hydroxide, a compound containing one sodium atom (Na) and one hydroxide group (OH).

5. NaCl: This is sodium chloride, commonly known as table salt, and contains one sodium atom (Na) and one chlorine atom (Cl).

6. Na: Finally, the sequence ends with sodium (Na) as a product.

It's important to note that this sequence appears to be incomplete or lacking some crucial information. The letter "P" in the first step could represent an unknown compound or element that is undergoing a series of reactions, but without more details, it's challenging to interpret the entire sequence fully. Additionally, chemical reactions typically require specific reaction conditions, such as temperature, pressure, and catalysts, which are not provided here.
