What else can I help you with?
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.
White phosphorus is always kept under water?
White phosphorus is a highly flammable and reactive substance that can ignite in air, so it is stored under water to prevent exposure to oxygen and potential combustion. This method helps to keep the white phosphorus stable and prevent accidents.
What color does titanium burn?
Titanium burns in a variety of colors depending on the temperature, ranging from white, yellow, orange, and red to purple, blue, and green. The colors result from the oxidation process that occurs when titanium is heated in the presence of oxygen.
Why white phosphorous has to be kept in water?
White phosphorus should be kept in water or under a layer of oil to prevent its exposure to air, as it is highly reactive and can spontaneously ignite upon contact with oxygen. Storing it submerged helps to reduce the risk of accidental fires and exposure to air. Additionally, white phosphorus can release toxic fumes, and storing it in water can help to contain these fumes and prevent them from dispersing.
Why white phosphorus has to be kept in water?
White phosphorus is highly reactive with oxygen in the air, leading to spontaneous combustion. Storing it in water helps to prevent exposure to air, which can ignite the phosphorus. Water also helps to keep the phosphorus cool, reducing the risk of fire or explosion.
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.
What is a filament that glows white hot in electric light bulbs?
Tungsten is the filament used in electric light bulbs that glows white hot when subjected to an electric current.
Why tube light glows white?
due to presence of Mercury
What gas glows with a white colour?
Tritium--a radioactive isotope of hydrogen
White phosphorous glows in the dark is it a chemical properties or physical?
This is a physical property because it describes a characteristic that can be observed without changing the composition of the substance. The ability of white phosphorus to glow in the dark is due to its property of emitting light when exposed to oxygen.
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.
White phosphorus is always kept under water?
White phosphorus is a highly flammable and reactive substance that can ignite in air, so it is stored under water to prevent exposure to oxygen and potential combustion. This method helps to keep the white phosphorus stable and prevent accidents.
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
What is the description of phosphorus?
It glows in the dark, colorless, red, silver, white, tasteless, garlic like odor.
What temperature is white heat?
White heat typically refers to the temperature at which a material glows white due to its high temperature, which is around 1,800 to 2,200 degrees Celsius.
Are white phosphorus glows in the dark physical or chemical?
The glow of white phosphorus in the dark is a result of a chemical reaction, specifically the oxidation of phosphorus. When exposed to oxygen, white phosphorus reacts and emits light due to the energy released during the reaction. This phenomenon is not a physical property like fluorescence, but rather a result of the chemical transformation taking place.
