When you snap a glow stick what does the snapping the tube do and how does it lead to chemical reaction?
I just had to do a project exactly on this, When you snap a glow stick a chemical change happens. A glow stick has an outer tube (the bendy one) and an inner glass tube (the one you hear cracking). By snapping a glow stick you are cracking open the inner tube which hold chemicals, the outer tube has phenyl oxalate and fluorescent dye in it, and the inner glass tube has a hydrogen peroxide solution in it. When these chemicals are released and come together, it releases energy in the form of light, thus, making a chemical change. So when you do your favorite activity with a glow stick, cracking it (admit it, it's your favorite part), you are breaking the inner glass tube, which then releases the hydrogen peroxide solution into the phenyl oxalate/dye solution, creating an enchantingly glowing stick of light! hope this was helpful! - Jessica
What is the test for oxygen and the result if oxygen is present?
If a test tube is filled with oxygen when you put a glowing splint into it, the splint will relight. (To make the splint glow you have to light it then blow it out and put it into the test tube immediately.) Hope this helps. XD XD
Where can you buy diphenyl oxalate?
i don't know if you can buy them but i know where you can get them, inside the small tube of a glow stick, the tube with the color liquid inside.
What colour blood tube to test inr?
Blue
What colour tube do you use for calcium testing?
green
Does the tube light glow with out starter and choke?
it will not glow
Do you put glow in the dark sticks in the dark or leave it in the light?
Glow sticks will show up better if you put them in the dark instead of leaving them in the light. Glow sticks are activated by breaking the tube inside and shaking them.
How does electron allow a fluroscent tube to glow?
The electrons in the mercury arc current in the tube causes the mercury vapor to emit ultraviolet light. The inside surface of the tube is coated with a phosphor that glows with visible light when hit by ultraviolet light.
What makes a glowstick glow?
Chemical lightsticks glow by way of two chemicals; cyalume and hydrogen peroxide. Inside the glowstick is a thin glass tube; inside of that is a chemical known as hydrogen peroxide. Outside of this tube, there is a chemical known as cyalume. When a glowstick is "cracked", the glass tube is broken, and when a glowstick is shaken the two chemicals mix together. These chemicals also activate a die of whatever colour the glowstick may be (pink, white, orange, green, red, etc.), causing the stick to "glow".
Why light emitted by a bulb is yellowish in colour but from a fluroscent tube is white?
You are seeing the spectrum of the metal used in a light bulb. In a florescent tube you are seeing ultraviolet light being transformed into visible light by the internal phosphor coating.
What do t5 slimming pills look like?
They are white or red in colour and are tube shaped.
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.

Why do fluroescent lights glow in the dark when swiched off?
A fluorescent tube contains (when operating) a plasma, and this excites phosphors coated on the inside of the tube. Some of these phosphors are phosphorescent, that is they will glow in the dark for a while due to being exposed to light. But that glow will soon cease. Other phosphors are fluorescent, that is they will glow only while excited. So the glow you observe is due to the phosphorescent particles in the coating, and they will soon diminish in brightness.
Why tube light glows white?
due to presence of Mercury
Why tube light glowing white colour?
Mercury is present inside the tube light.When we give supply to the tube light the mercury vapours excites and it produces uv radiation which then strikes the fluorescent material and produces light. Therefore it is called fluorescent light.
What are the positive points of ulteraviolet rays?
Ultraviolet rays can be used as for fluorescent lamps as certain chemicals glow when they absorb ultraviolet. In fluorescent lamps, the sindide of the tube is coated with a white powder that gives off light when it absorbs ultraviolet. The ultraviolet is produced by passing a current through a gas in the tube.
