When you crush a glow stick and shake it the two liquids mix and the stick glows. Is this a chemical reaction and is energy being absorbed or given off?
In a glow stick a chemical reaction occur; the energy is released.
What is the chemical property of a glow stick how do you compare chemical properties?
Glow sticks produce an chemical property called chemiluminescence. This means that chemical reactions produce light. Glow sticks are made of three chemicals: diphenyl oxalate, hydrogen peroxide, and a fluorescent dye. The hydrogen peroxide is contained in a glass vial suspended in the diphenyl oxalate/dye solution, which is inside the glow stick itself. When you bend the plastic glow stick far enough, it breaks the glass vial inside, which releases the hydrogen peroxide, causing it to mix with the diphenyl oxalate and dye. When this happens, a chemical reaction occurs that breaks the diphenyl oxalate into two molecules of phenol and a peroxyacid ester. The peroxyacid ester decomposes into carbon dioxide and releases energy in the process. The energy is absorbs by the fluorescent dye, which is then re-emitted as a photon (light).
What is the chemical that is inside the lighted Christmas necklaces?
The chemical inside lighted Christmas necklaces or glow necklaces is called dibutyl phthalate. Other glow products also use a mixture of hydrogen peroxide dissolved in phthalic ester.
What chemicals make a highlighter glow?
There are three chemicals used to make this one called the omnihil another glomji and the last hingti. They make glow if there is a source of light.
What are some examples of chemical reaction?
Rusty Nails: A chemical reaction between the iron in steel and oxygen in the atmosphere causes rust. Photographic film: There is a chemical reaction on the film wherever light hits it. Batteries: Chemical reactions within batteries produce electrons called electrochemical reactions. Halloween Lightsticks: A chemical reaction excites atoms causing the stick to glow. Homemade Volcano: When baking soda and vinegar are combined, they erupt as carbon dioxide gas is released. Fizz Fizz: Dropping an Alka-Seltzer tablet in water makes a bubbling chemical reaction. An Old Fruit Salad: Cut a piece of fruit open and it soon turns brown, reacting to the oxygen in the air. Bubbles, and heat change are examples of chemical reactions. When a chemical reaction happens, a compound is formed. It cant be separated. Another example could be change of colour.
When you crush a glow stick and shake it the two liquids mix and the stick glows. Is this a chemical reaction and is energy being absorbed or given off?
In a glow stick a chemical reaction occur; the energy is released.
Does baking soda and water make a glow stick glow?
No. Glow stick uses a rather complicated chemical reaction that involves, among other things, hydrogen peroxide and a fluorescent dye.
How long does a glow stick glow?
Glow sticks can last over 4 days if you get the right ones. It usually depends on the colour and size of your glow stick. To make the glow stick last longer throw it in the fridge freezer to slow the chemical reaction down.
Are glow sticks made with water?
There is no water used in the making of a standard glow stick, it is simply a chemical reaction between two chemicals. Water can however be used to make a glow stick brighter.
Is a glow stick endothermic or exothermic?
a glow stick can be a endothermic or exothermic reaction
Is breaking a glow stick a chemical or physical change?
It's a chemical change--there's a glass ampule in the glow stick. and it's got one chemical in it. Around it is another chemical. When you break the glow stick the two chemicals mix, and the glow happens.
Does the liquid inside a glow stick stain clothes or hurt wood floors?
Yes there is a pigment in the stick after the chemical reaction & it will stain floors & textiles
Is a glow stick that produces light a chemical change?
Yes, a glow stick produces light by means of a chemical change.
What are some examples of chemical energy being converted into light energy?
A perfect example is a common glow stick. In a glow stick, phenyl oxalate, fluorescent dye, and hydrogen peroxide mix to produce a chemiluminescent reaction (generating light from chemical energy).
What type of reaction occurs in a glow stick?
Decomposition.
What are the insects that make the ocean shiny called?
They are called Photoluminescent Plankton. When touched, there is a chemical reaction that causes them to glow-in-the-dark.
How does temperature in a luminol reaction affect light produced?
If the temperature of the glow stick (chemiluminescence) is warmer, it releases a brighter glow and has a shorter reaction time. If the temperature of the glow stick is colder, it releases a dimmer glow but has a longer reaction time. Lower temperatures slow reaction rates and release less light intensity then higher temperatures.
