How Do Glow Sticks Glow?

Chemistry
1 answer:
Gekata [30.6K]3 years ago
8 0

Answer:

All liquid glow products depend on a chemical process known as CHEMILUMINESCENCE to produce their light. Chemiluminesence is a chemical reaction that causes a release of energy in the form of light. To produce this light the electrons in the chemicals become excited and rise to a higher energy level.

To utilise this process glowsticks contain two liquids; hydrogen peroxide and tert-butyl alcohol. When mixed together it is these liquids that create the glow. Fluorescent dyes are also used in the alcohol to alter the colour of the light emitted.

Que relación tiene el metabolismo celular con el mantenimiento de los seres vivos
Dmitry [639]
El metabolismo es un proceso por el cual los seres vivos ganan masa y energía que ofrece el medio en el que viven y sirve para el mantenimiento, crecimiento y reproducción de estos.

Si tomamos en cuenta la clasificación de los seres vivos tenemos:

- Autótrofos: Crean su propio alimento por medio del sol o la tierra y no de otros seres vivos (plantas, vegetales y algas).

- Heterótrofos: Generan su propio alimento y dependen de los autótrofos o de otros heterótrofos para su alimentación (animales y algunas bacterias).

El metabolismo se divide en dos procesos conjugados, el catabolismo y el anabolismo. Estos procesos dependen el uno del otro.

Las reacciones catabólicas liberan energía, mientras que las reacciones anabólicas, utilizan esa energía liberada para recomponer enlaces químicos y construir componentes de las células como las proteínas y los ácidos nucleicos..

De esta manera se relacionan ambos

How does increasing the concentration of a nonvolatile solute in water affect the following properties:Vapor pressure: Decreases
PIT_PIT [208]

Answer: Osmotic pressure : increases

Explanation:

Osmotic  pressure is the minimum pressure which is applied to  a solution to prevent the flow of solvent across a semipermeable membrane

\pi =CRT

\pi= osmotic pressure

C= concentration in Molarity  (number of moles of solute dissolved per liter of the solution)

R= solution constant

T= temperature

Thus as osmotic pressure is directly proportional top concentration, osmotic pressure will increase on  increasing the concentration of a nonvolatile solute in water.

Natalie observes these characteristics in the model of an atom.
PilotLPTM [1.2K]
An atoms consists of protons, electrons and neutrons. Protons are positively charged while electrons are negatively charged. Both are electrically attracted to each other. Meanwhile, the neutrons are electrically neutral which do not  have a charge. This means that neutrons are neither  electrically attracted to the protons nor electrons,
