What is the difference between phosphorescent and bioluminescent light emission?
Phosphorescent light emission occurs when a material absorbs and stores energy from a light source, then slowly releases it over time. Bioluminescent light emission, on the other hand, is produced by living organisms through a chemical reaction within their bodies.
Is a glow stick chemical change?
Yes, the glow stick undergoes a chemical change when it is activated. The chemical reaction between the components inside the stick creates the light emission.
What are the products and reactants of glow sticks?
In a glow stick, the products formed are chemical compounds that emit light due to a chemical reaction called chemiluminescence. Typically, this reaction involves a hydrogen peroxide solution and a dye molecule, resulting in the emission of light. The reactants are the chemicals present in the glow stick that undergo the reaction to produce light.
If you watch exploding fireworks from a safe distance hat evidence of a chemical reaction can you observe?
Burning of metals in fireworks is a chemical reaction and is what makes the fireworks glow with different colors.
Is a glow stick that produces light a chemical change?
Yes, a glow stick produces light by means of a chemical change.
Is emission of light a chemical or physical change?
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.

If burning sugar is a chemical reaction can you give me an evidence?
One evidence that burning sugar is a chemical reaction is the production of heat and light during the process. This indicates a change in the chemical composition of the sugar molecules as they react with oxygen in the air, releasing energy in the form of heat and light. Additionally, the formation of new substances such as carbon dioxide and water from the sugar molecules further supports the occurrence of a chemical reaction.
What is bioluminous means?
Bioluminescence is the production and emission of light by living organisms, such as certain fish, insects, and microorganisms. These organisms possess special molecules that produce light through a chemical reaction.
Is a firefly emitting light chemical or physical change?
That would be a chemical change because the firefly produces a bio-luminescent chemical. This chemical produces light which you see when the fire fly lights up!
Is a glow sticks reaction endergonic or exergonic?
The reaction in a glow stick is exergonic because it releases energy in the form of light. The chemical reaction between the two chemicals in the glow stick results in the emission of light without requiring an external source of energy.
What is photo chemical reaction?
chemical reaction brought on by light ( latin: photo - light)
Is a flame a source of light?
The flame of a candle is a source of light.
