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.
What else can I help you with?
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.
Is white phosphorus ignites easily chemical or physical?
The ease of ignition of white phosphorus is a chemical property. This property relates to its reactivity and the energy changes that occur during the combustion process, which involves a chemical reaction with oxygen. Physical properties, on the other hand, pertain to the state or appearance of a substance without changing its chemical identity. Thus, the ignition of white phosphorus is fundamentally a chemical characteristic.
Is white waxy solid a physical or chemical property of phosphorus?
The white waxy solid form of phosphorus is a physical property. This characteristic describes its appearance and state at room temperature, without altering its chemical composition. Physical properties can be observed and measured without changing the substance's identity, unlike chemical properties, which involve reactions that result in a new substance.
What reactive non metal is a solid that comes in 3 forms?
Phosphorus -I didn't really know the answer until i checked my chemistry crossword extra credit. May be we are in the same class. LOL 39.9999% we are in the same chemistry class. Mr.Brown Save
What chemical is phosphorus 4 oxygen 10?
It is phosphorus pentaoxide P2O5 which exists in dimeric form P4O10.
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 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.
Is phosphorus invisible?
Phosphorus is not invisible. It is a chemical element that is typically found in a solid state (white phosphorus) or as a part of various compounds. White phosphorus appears colorless or slightly yellow in daylight and glows green in the dark.
Its white variety glows upon exposure to oxygen?
The substance you're referring to is phosphorus. White phosphorus is very reactive and glows in the dark due to its exposure to oxygen, a process known as chemiluminescence. This unique property makes it useful in military applications for incendiary devices and smoke screens.
Is white phosphorus ignites easily chemical or physical?
The ease of ignition of white phosphorus is a chemical property. This property relates to its reactivity and the energy changes that occur during the combustion process, which involves a chemical reaction with oxygen. Physical properties, on the other hand, pertain to the state or appearance of a substance without changing its chemical identity. Thus, the ignition of white phosphorus is fundamentally a chemical characteristic.
What unusual or special properties does phosphorus have?
Phosphorus has the property of existing in various allotropes, such as white, red, and black phosphorus, each with different physical and chemical properties. It is also an essential element for life, being a key component of DNA and RNA. Additionally, phosphorus can exhibit luminescence when exposed to ultraviolet light, making it useful in applications such as inorganic LEDs.
Is White phosphorous ignites easily a physical change?
Yes, white phosphorus igniting is a physical change because it involves a change in the physical state of the substance (from solid to gas) without altering its chemical composition.
What are all the elements that make up a phosphorus?
Phosphorus is a chemical element with symbol P and atomic number 15. It is a nonmetal with multiple allotropes, including white phosphorus, red phosphorus, and black phosphorus. Each allotrope has different physical and chemical properties.
Is white waxy solid a physical or chemical property of phosphorus?
The white waxy solid form of phosphorus is a physical property. This characteristic describes its appearance and state at room temperature, without altering its chemical composition. Physical properties can be observed and measured without changing the substance's identity, unlike chemical properties, which involve reactions that result in a new substance.
What are facts about phosphorus Like stuff that most people dont know?
this element glows from white phosphorus and is an allotropeit comes in colorless waxy whiyt
What is the description of phosphorus?
It glows in the dark, colorless, red, silver, white, tasteless, garlic like odor.
What are three allotropes of phosphorus how are they different?
The three allotropes of phosphorus are white phosphorus, red phosphorus, and black phosphorus. White phosphorus is a highly reactive and toxic form that glows in the dark, red phosphorus is more stable and less reactive, and black phosphorus has a layered structure similar to graphite and exhibits semiconducting properties.
