Glow sticks are an example of what type of chemical reaction?

Exergonic reaction

Explanation:

The glow sticks are made of plastic case within which there is a small glass capsule.

     The outer tube contain chemical diphenyl oxalate and a dye which determine the color of the glow stick.

     The inner glass capsule consists of hydrogen peroxide.

When the outer tube is bent the small capsule containing hydrogen peroxide is broken. The substance in the glow stick  and reaction takes place releasing carbon di oxide and chemical energy  which is converted to visible light.

The reaction does not produce light but the reaction has energy to excite the electrons in the dye and when electron return from higher energy level to lower energy level they emit photons ie light.

The energy is released in form of light and it is and exergonic reaction.

The light produced is an example of chemiluminescence.

The light can be made to shine bright and brief or dim and long lasting by changing ratio of the compounds used and also by changing temperature.

ie when the glow stick is bent in hot water it glows brightly for short period due to high energy of molecules.

quantum mechanics or quantum physics is physics of very small objects (particles) and physical entities.

quantum physics has some parallels to our macro world and some pretty unique ideas which theoretically and mathematically proven to be true even though we will never be able to access them because of our size.

there are many types of particles: subatomic, elementary etc.

subatomic means they are smaller than atom, elementary means they are at the very basis of everything.

subatomic particles are for eg. protons, neutrons but not electrons.

elementary particles are categorised into 3 groups by what they do.

these 3 groups are quarks, leptons and bosons.

light for example is a particle more precisely a photon a part of leptons.

proton (subatomic particle) is made out of 2 up quarks and 1 down quark each of these has a fractional charge like . (i crazy)

most famous scientist who contributed to this physics are:

the topic itself us understand a lot and will probably be vastly used in the future (quantum computers, understanding the big bang,

we also must not forget quantum effects like:

and there is more. but probably too much for this answer to be consistent due to my average understanding of this topic.

hope this you understand quantum mechanics a little more. i'm not an expert in the topic (so don't be like wth if you are an expert) but i'm very interested in it.

anyways quantum physics is a very hard topic (harder than physics (perhaps)) therefore searching for every information there is about it and learning it is unfortunately impossible (you can only specialise into 1 - 3 things or more (perhaps

have fun and i wish you luck!
