Its white variety glows upon exposure to oxygen?
This is the element phosphorus, its white allotrope glows ( chemiluminescence ) when exposed to oxygen
Why phosphorus stored in water?
Phosporous is stored in water because it is very reactive non metal and when exposed to air it catches fire easily and ignites.To prevent contact with atmospheric oxygen it is stored in water.
White phosphorus is always kept under water?
Because it will spontaneously react with the oxygen in the air.
What is the difference between red phosphorus and white phosphorus?
White phosphorus is obtained by roasting Calcium phosphate rocks and then reducing them using silica White phosphorus reacts with air vigorously that is it burns instantly in presence of oxygen and show phophorescence property ( it emits bright luminous green light in dark in prsence of small amount of oxygen ) , hence it is stable below 125'C and red phosphorus is stable above 125'C. If you heat white phosphorus upto 125'C in absence of air you get red phosphorus. White phosphorus has 4 atoms of P linked in tetrahedral shape, where as red phosphorus have amorphous network arrangement hence red phosphorus is more stable. White P is soluble in carbon di sulfide and small amount in water, but red P is not soluble in both water and carbon disulfide. white P is used in explosives, incendiaries, bullets etc
Is white phosphorus that glows when exposed to air a chemical change or a physical change?
White phosphorus is a very reactive chemical because of its structure. When it is heated some, it can react with oxygen to create phosphorus pentoxide (it is in this exothermic reaction that you see the glow). So it is indeed a chemical change.
Does white phosphorus burn easily?
White phosphorus is very flammable.
What is phosphor burn-in?
White phosphorus is very flammable.
How many moles of oxygen are needed to burn 7.0 mols of phosphorus?
8,75 moles of oxygen are needed.
At what max temp does white phosphorus burn?
5000 Degrees Fahrenheit.
Its white variety glows upon exposure to oxygen?
This is the element phosphorus, its white allotrope glows ( chemiluminescence ) when exposed to oxygen
Which element of the periodic table can burn without oxygen?
It depends upon the group number.I mean oxides are basically burn when reacted with oxygen.
What is used in fire grenades?
White phosphorus, it is a chemical that catches fire on contact with oxygen.
White phosphorus is always kept under water?
Because it will spontaneously react with the oxygen in the air.
Why phosporus kept in water?
Potassium is a soft metal which reacts violently (spontaniously combusts) with both water and oxygen, so both must be excluded, by storing it in paraffin or kerosene. Phosphorus is a non metal .White phosphorous is kept under water because it reacts with oxygen but not water. Red phosphorus (the allotropic form P4, which occurs when white phosphorus is heated above 275`C) is more inert and does not need to be kept in water to exclude air.
Why phosphorus stored in water?
Phosporous is stored in water because it is very reactive non metal and when exposed to air it catches fire easily and ignites.To prevent contact with atmospheric oxygen it is stored in water.
