Phosphorus burns in air because it undergoes rapid oxidation, forming phosphorus pentoxide (P4O10) as a product. Phosphorus is highly reactive and readily combines with oxygen to form this compound, which appears as a white smoke when exposed to air. This reaction releases a significant amount of heat energy as well.
What else can I help you with?
What fraction of the air does phosphorus use when it burns?
When phosphorus burns, it consumes about one-fifth (1/5) of the available oxygen in the air. This creates phosphorus pentoxide, a compound formed from the reaction of phosphorus with oxygen.
What happens when phosphorus burns?
When phosphorus burns, it produces a bright white light due to the combustion reaction with oxygen in the air. The reaction forms phosphorus pentoxide as the main product, releasing heat energy in the process. Burning phosphorus can also produce toxic phosphorus oxides as byproducts.
What element whose name light-bearing burns spontaneously in air?
Phosphorus is the element that ignites spontaneously in air due to its high reactivity. When exposed to oxygen, phosphorus can catch fire and burn brightly, producing light, hence the nickname "light-bearer."
Which metal burns in air?
Sodium, Potassium, and Phosphorus all burn upon contact with air.
What temperature does red phosphorus burn at?
Red phosphorus burns at temperatures ranging between 300°C to 400°C.
Word equation to represent what happens when phosphorus burns?
Phosphorus burns at very high temperatures, about 1600-1800oC, phosphorus is the red tip at the end of a kitchen match. The chemical formula for the combustion of Phosphorus is: P4 + 5 O2 yields P4O10

Phosphorus is the element that ignites spontaneously in air due to its high reactivity. When exposed to oxygen, phosphorus can catch fire and burn brightly, producing light, hence the nickname "light-bearer."
What color flame do you get with phosphorus?
When phosphorus burns, it produces a pale green flame.
Which metal burns in air?
Sodium, Potassium, and Phosphorus all burn upon contact with air.
What burns when you light a match heads?
Phosphorus and sulfur.
What temperature does red phosphorus burn at?
Red phosphorus burns at temperatures ranging between 300°C to 400°C.
What is a balance equation of phosphorus burns in chlorine to form phosphorus pentachloride?
The balanced equation for phosphorus burning in chlorine to form phosphorus pentachloride is: P4(s) + 10 Cl2(g) -> 4 PCl5(s)
Can white phosphorus be stored inside the mouth for a brief period during a magic show and then spit it out to produce fire?
No, it is extremely dangerous to store white phosphorus in the mouth. White phosphorus can ignite spontaneously in contact with air and can cause severe burns or even be fatal if ingested or inhaled. It should never be used in magic shows as a fire-producing effect.
Why do phosphorus smoulder?
Phosphorus can smoulder because it reacts with oxygen in the air to produce heat, which can ignite the material. This reaction is exothermic, meaning it releases energy in the form of heat. Smouldering occurs when the phosphorus burns at a low temperature without a visible flame.
What element stinks when it burns?
Phosphorus is an element that emits a distinct garlic-like odor when it burns.
