How do fireworks work on the atomic level and the chemical level?

Fireworks utilize a rapid chemical reaction between a fuel and an oxidizer to release energy is the form of heat, light, and sound.\n\nGun powder is a common firework chemical.  Gun powder is made out of mixture of Sulfur, Charcoal, and Potassium Nitrate.  The Sulfur and Charcoal act as the fuel and the Potassium Nitrare acts as the Oxidizer.  When the power is ignited, the chemicals react together very quickly to produced to "explosive" results.

its called convection.......the land heats, the heat rises and mixes with moisture and dust to create clouds. this continues until the cloud reaches a dew point. then, as you are aware, the fireworks begin. up and down drafts of heat and cool air mix causing the system to increase and errupt.

That should only happen with copper or copper salts.\nIt's the oxidation of the copper in the flame.\nAll elements burn differently, this is the basis of how a spectrometer works.

In chemical qualitive analysis, this is known as a flame test.  Many metals (and some non-metals) have distinctive colors.\n\nThe heat of the flame excites one or more electrons of the metal atom causing it to go to a higher energy state.  When the electron returns to the "ground state" electromagnetic energy is released and this appears as light of a specific color.

Paint the protons one color, the neutrons another, and the electrons another. Put the nucleus together with the correct number of protons & neutrons. Put the correct # of electrons on it so that they appear to have some distance between them and the nucleus in an evenly spread manner. pretty simple. Styrofoam balls and toothpicks work great.

You mentioned candles and as these are composed of Hydrocarbons I'd refer you to Hinshelwood (Step Reactions), but you asked this in Physics, not Chemistry. \n\nSimply put, A candle flame consists of different molecular combinations of Carbon, Hydrogen and Oxygen.  They are not ionised but are neutral (some of these as free radicals). The valence electrons are highly energised and (as they fall to lower Molecular orbitals) emit photons  - some of which are in the visible range.\n\nSo not (an ionised) plasma - just a hot gas!

Nothing...unless you light a match, then...BOOM!  In the case of Oxygen and Hydrogen, you'll get pure water afterwards...that should put out the fire you just started :)\n(Not really)

Add some baking soda first and then pour on some vinegar. You will observe some bubble forming and the bublbles will rise very quickly. If you want to make fire instead, add some glycerine to potassium permagnate. Be very careful if you want to do this.

i learned about this in chem.  it's hard to explain...but if you put a cd in your microwave(if your parents allow u 2) then you can see it.  if u need help, you could e-mail my teacher by getting his e-mail address from his website below.  hope that helps!

Most students of the modern Life Saver classify sparking as a type of triboluminescence, which occurs when something is crushed or torn, the something in this case being the hard crystalline sugar that Life Savers contain. (Another example of TL is the spark you get when you tear the piece of tape off the end of a roll of photographic film.)\n\nWintergreen sparking, it's believed, is actually a three-step process. Step One: When you shatter the sugar crystals with your teeth, electrons (which are negatively charged) break free. As a result, the atoms in which the electrons were formerly embedded become positively charged. In what amounts to a subatomic game of musical chairs, the free electrons dash around madly trying to find a new home.\n\nStep Two: Meanwhile, as the sugar crystals disintegrate, nitrogen molecules from the air attach themselves to the fractured surfaces. When the free electrons strike the nitrogen molecules, they cause the latter to emit invisible ultraviolet radiation, along with a faint visible glow.\n\nStep Three: The UV radiation is absorbed by the wintergreen flavoring, methyl salicylate. This then emits the fairly bright blue light you see. Pretty complicated, I admit. Clearly the planners in the Pentagon weren't the first to be obsessed with high-tech gimcracks.\n\nI should point out that even without the wintergreen flavoring, virtually all crystal sugar candy, including peppermint Life Savers, will emit some visible light when crushed, although it's usually pretty faint. The effect was first described in 17th-century Italy, and since then it's been discussed in numerous papers and articles.\n\nSome of these are more imaginative than others. For instance, I have here an unpublished paper by researcher Patricia Nakache that is somewhat grandly entitled, "The Life Saver: A New Energy Source?" It contains the fascinating news that if you connect a Life Saver to a neon tube with wires and bash it (the Life Saver) with a hammer, the neon tube will flash. We can thus envision that when the next energy crunch comes, an adequate supply of Life Savers will be as important to survival as MasterCard is today. Better hustle on down to the store toot sweet.

Short answer: you can't burn salt.\n\nLong answer: burning typically refers to something + oxygen --> carbon dioxide + water.  Salt simply cannot undergo that reaction.  Some salts can contain organic matter which can be burned, but most salts do not.  Furthermore, some salts contain metals which, when electronically excited by the heat of the flame, emit colors (this is how fireworks generate color--different metals give different colors).  But you're not burning the salt.  By the way, you may not be burning the sugar either--it takes a while to burn it, at first you just melt it.

It depends on the type of fireworks you are attempting to shoot off. \n\nCheck the links below of more info.

The energy levels for an electronic change (chemical combination) and for a nuclear change (radioactive decay) are so far apart that there is essential no coupling between the processes.  In other words the two processes will act independently.

The manufactures take a couple of lasers (2-3), each laser not having enough heat/energy to melt the crystal. Then they cause the lasers to intersect at each point that they want one of those little bubbles to appear and where the lasers intersect they add their energy together and melts the crystal. the placement of each dot is controlled by a 3-d graphics design inside of a computer.

The doesn't really "burn" in the sense of chemically combining hydrogen and oxygen.  It shines because of energy produced by nuclear fusion.\n\nIn physics, nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus. It is accompanied by the release or absorption of energy depending on the masses of the nuclei involved. Iron and nickel nuclei have the largest binding energies per nucleon of all nuclei and therefore are the most stable. The fusion of two nuclei lighter than iron or nickel generally releases energy while the fusion of nuclei heavier than them absorbs energy; vice-versa for the reverse process, nuclear fission.\n\nNuclear fusion of light elements releases the energy that causes stars to shine and hydrogen bombs to explode. Nuclear fusion of heavy elements (absorbing energy) occurs in the extremely high-energy conditions of supernova explosions. Nuclear fusion in stars and supernovae is the primary process by which new natural elements are created. It is this reaction that is harnessed in fusion power.\n\nIt takes considerable energy to force nuclei to fuse, even those of the least massive element, hydrogen. But the fusion of lighter nuclei, which creates a heavier nucleus and a free neutron, will generally release more energy than it took to force them together — an exothermic process that can produce self-sustaining reactions.\n\nThe energy released in most nuclear reactions is much larger than that for chemical reactions, because the binding energy that holds a nucleus together is far greater than the energy that holds electrons to a nucleus. For example, the ionization energy gained by adding an electron to a hydrogen nucleus is 13.6 electron volts -- less than one-millionth of the 17 MeV released in the D-T (deuterium-tritium) reaction shown to the top right.\n\nThe steps of the main cycle of nuclear fusion in stars were worked out by Hans Bethe.  He won the Nobel prize for this work.
