Answer 1

Ответ:

4P+5O2=2P2O5 реакция горения

P2O5+3H2O=2H3PO4 типичная реакция получения кислоты из кислотного оксида

H3PO4+3KOH=K3PO4+3H2O типичная реакция получения соли

Answer 2

The given expression seems to be a chemical equation involving the elements P (phosphorus), O (oxygen), H (hydrogen), and K (potassium). Let's break down the equation step by step:

1. P -> P²O⁵: This equation represents the reaction where phosphorus (P) reacts with oxygen (O) to form diphosphorus pentoxide (P²O⁵). Diphosphorus pentoxide is a white, crystalline solid that is commonly used as a dehydrating agent in chemical reactions.

2. P²O⁵ -> H³PO⁴: In this step, diphosphorus pentoxide (P²O⁵) reacts with water (H₂O) to form phosphoric acid (H³PO⁴). Phosphoric acid is a colorless, odorless liquid that is commonly used in fertilizers, detergents, and food and beverage products.

3. H³PO⁴ -> K³+PO⁴: Finally, phosphoric acid (H³PO⁴) reacts with potassium hydroxide (KOH) to form potassium phosphate (K³+PO⁴). Potassium phosphate is a salt that is commonly used as a fertilizer and food additive.

Please note that the given equation is a simplified representation of the chemical reactions and may not accurately reflect the stoichiometry or conditions of the actual reactions.
