Question

Урівняй рівняння реакції процесу окиснення PHз при підвищенній температурі в атмосфері кисню: PH3 + O2 = H2O + P05. пожалуйста помогитеееее:(​

Answer 1

Ответ:

Объяснение:

2PH₃ + 4O₂ = P₂O₅ + 3H₂O

P⁻³ - 8e⁻ = P⁺⁵          4   2  процесс окисления

O₂⁰ + 4e⁻ = 2O⁻²      8   4  процесс восстановления

Answer 2

Balancing the Reaction Equation for the Oxidation Process at Elevated Temperature in Oxygen Atmosphere

When balancing a chemical reaction equation, it's important to ensure that the number of atoms of each element is the same on both sides of the equation.

The reaction given is: PH3 + O2 = H2O + P

To balance this equation, we can follow these steps:

1. Balance the phosphorus atoms first, as it appears only once on each side of the equation. 2. Then balance the hydrogen and oxygen atoms. 3. Finally, balance any remaining atoms, in this case, oxygen.

Balancing the Equation

The balanced equation for the reaction of phosphine (PH3) with oxygen (O2) to form water (H2O) and phosphorus pentoxide (P4O10) at elevated temperatures in an oxygen atmosphere is:

4 PH3 + 5 O2 = P4O10 + 6 H2O [[1]]

This balanced equation ensures that the number of atoms of each element is the same on both sides of the equation, satisfying the law of conservation of mass.
