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.
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.
Is phosphorus toxic or nontoxic?
Toxic. White phosphorus is extremely poisonous and in many cases exposure to it will be fatal

Why tungsten glows?
tungsten is a poor conductor of electricity,tungsten glows when electrical energy from the energy source is flowing through the conductor of electricity and when electrical energy reach the metal filament(tungsten) the tungsten gets electrical energy and produce heat when it became white-hot and the tungsten glows the glows is called light.
What is the chemical compound that create white in firework?
Magnesium is added to fireworks and it glows bright white. It is added to fireworks to make bright white flashes.
Why does a poster glow under black light?
A poster glows under black light if there is white designs on it. Anything white glows under black light. The reason why is because those things have phosphors on them which can only be detected under black light.
What causes white wine to become darker as it ages?
Exposure to air or oxygen. You have seen a piece of an apple or some other fruit, after it has been sitting for a while, turn brown.
What happens to noble gases when electricity flows through them?
They glow a certain color. Helium glows pink, Krypton glows dark blue, Argon glows light blue, Xenon glows purple, Neon glows orange, Radon and Ununoctium, well, no one knows their color because of their dangerous nature.
How tubelights glow in buses?
tubelights in buses are made to glow by the inside being painted with this paint which glows when it comes into conatct with a noble gas for example argon. The paint glows producing a white light
