White phosphorus burns in oxygen to form phosphorus pentoxide, releasing a large amount of energy in the form of heat and light. This reaction is highly exothermic because phosphorus has a high affinity for oxygen, resulting in a rapid and intense combustion process.

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 that glows when exposed to air a chemical change or a physical change?
White phosphorus that glows when exposed to air is a chemical change. This phenomenon occurs because white phosphorus undergoes a chemical reaction with oxygen in the air to form phosphorus oxide, releasing energy in the form of light.
What colour flame do you get when you burn phosphorus?
When phosphorus is burned, it produces a bright white flame, which is due to the high temperature of the combustion process. The white flame is intense and can be used in pyrotechnic displays.
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 can a white phosphorus be extinguished?
White phosphorus can be extinguished by smothering the flames with sand, cutting off its oxygen supply. Water should not be used to extinguish white phosphorus fires, as it can react with the chemical and make the fire worse. Firefighters should use caution and appropriate protective gear when dealing with white phosphorus fires.
Does white phosphorus burn easily?
White phosphorus is very flammable.
Which element of the periodic table can burn without oxygen?
Phosphorus is an element that can burn without oxygen through a process called spontaneous combustion. When exposed to air, phosphorus can react with the oxygen in the air to produce phosphorus oxide and ignite.
How many moles of oxygen are needed to burn 7.0 mols of phosphorus?
8,75 moles of oxygen are needed.
What is white powder if you burn it and it turns red?
The white powder is likely phosphorus. When phosphorus is burned in air, it produces white fumes and eventually turns into phosphorus pentoxide, which appears as a red powder.
Is phosphorus corrosive?
Phosphorus itself is not typically corrosive. However, certain forms of phosphorus, such as white phosphorus, can react with oxygen in the air to form phosphoric acid which can be corrosive. White phosphorus is also highly flammable and toxic.

What is formed by heating phosphorus with oxygen gas?
Do you mean heating Phosphorus THEN putting it in oxygen gas? Because the reaction that will create is glowing and also condensation that causes vapor. The description of the gas is opaque and white. Not really sure what the gas is tho...
How can a white phosphorus be extinguished?
White phosphorus can be extinguished by smothering the flames with sand, cutting off its oxygen supply. Water should not be used to extinguish white phosphorus fires, as it can react with the chemical and make the fire worse. Firefighters should use caution and appropriate protective gear when dealing with white phosphorus fires.
At what max temp does white phosphorus burn?
White phosphorus ignites around 30°C and burns at a maximum temperature of around 1,200°C to 1,500°C.
