Answer 2

P, P2O5, H3PO4, Na3PO3

P, P2O5, H3PO4, and Na3PO3 are all chemical compounds that contain phosphorus (P) as one of their elements. Let's discuss each compound in detail:

Phosphorus (P): Phosphorus (P) is a chemical element with the atomic number 15. It is a nonmetal that belongs to Group 15 of the periodic table. Phosphorus is highly reactive and can form various compounds with other elements.

P2O5: P2O5 is the chemical formula for diphosphorus pentoxide. It is an oxide of phosphorus and is commonly referred to as phosphorus pentoxide. P2O5 is a white, crystalline solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. It reacts vigorously with water to form phosphoric acid (H3PO4). P2O5 is often used as a dehydrating agent in organic synthesis and as a catalyst in certain chemical reactions.

H3PO4: H3PO4 is the chemical formula for phosphoric acid. It is a weak acid that contains three hydrogen atoms, one phosphorus atom, and four oxygen atoms. Phosphoric acid is a colorless, odorless liquid that is commonly used in fertilizers, detergents, and food and beverage products. It is also used in the production of various chemicals and pharmaceuticals.

Na3PO3: Na3PO3 is the chemical formula for sodium phosphite. It is an inorganic compound that contains sodium (Na) and phosphite ions (PO3^3-). Sodium phosphite is a white, crystalline solid that is soluble in water. It is used in various industrial applications, including as a reducing agent, a corrosion inhibitor, and a stabilizer in electroplating processes.
