Question

Электронная формула составить помогите PH3+O3=P2O3+H2O

Answer 1

2P⁻³H₃ + 2O₃⁰ = P₂⁺³O₃⁻² + 3H₂O⁻²

P⁻³ - 6e = P⁺³       фосфор восстановитель, процесс окисления
O₃⁰ + 6e = 3O⁻²   озон окислитель, процесс восстановления

Answer 2

Electron Configuration and Balanced Equation

To determine the electron configuration and balanced equation for the reaction between PH3 and O3 to form P2O3 and H2O, we need to consider the valence electrons of each element involved.

The electron configuration of phosphorus (P) is 1s^2 2s^2 2p^6 3s^2 3p^3, which means it has 5 valence electrons. Hydrogen (H) has 1 valence electron, and oxygen (O) has 6 valence electrons.

The balanced equation for the reaction is as follows: 2 PH3 + 3 O3 → P2O3 + 3 H2O

Explanation

In the reaction, two molecules of PH3 (phosphine) react with three molecules of O3 (ozone) to produce one molecule of P2O3 (diphosphorus trioxide) and three molecules of H2O (water).

To balance the equation, we need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, we have:

- Phosphorus (P): 2 atoms on the reactant side and 2 atoms on the product side. - Hydrogen (H): 6 atoms on the reactant side and 6 atoms on the product side. - Oxygen (O): 9 atoms on the reactant side and 9 atoms on the product side.

Therefore, the equation is balanced.
