Question

Реакция фосфора с кислородом

Answer 1

При недостатке кислорода:
4P+3O₂=2P₂O₃
при избытке кислорода:
4P+5O₂=2P₂O₅

Answer 2

Reaction of Phosphorus with Oxygen

The reaction of phosphorus with oxygen can result in different phosphorus oxides, depending on the conditions and the amount of oxygen present.

Under standard conditions, phosphorus reacts with oxygen to form phosphorus(V) oxide, P4O10. This reaction is highly exothermic and produces a bright light. The balanced chemical equation for this reaction is:

4P + 5O2 → P4O10 Under controlled conditions, phosphorus can also react with oxygen to form phosphorus(III) oxide, P4O6. The balanced chemical equation for this reaction is:

P4 + 3O2 → P4O6 These reactions are important in understanding the chemical properties of phosphorus and its oxides.
