The brilliant colors you see when the fireworks explodes comes from a wide variety of metal salts that are packed inside the firework. Now, when most people think of salt they're thinking of the white crystals they sprinkle on their food. That is a salt, but it's not the only salt. That's sodium chloride (NaCl). A salt is any metal atom bound to a non-metal atom. In the case of table salt, sodium is the metal and cholrine is the non-metal. When these salts burn they absorb energy, exciting electrons in the atoms. The excited electrons jump up to a higher energy level, but they are very unstable in that higher energy state. When the electrons relax back to their low energy state they release a photon of light. The color of light changes depending on the metal salt that is used. So, for example, strontium salts burn red, calcium shines orange, green is from barium, white is from magnesium, and copper shines a beautiful blue. Combinations of these salts yields the combinations of their colors (strontium and copper shines purple).
.Their colors come from the different temperatures of hot, glowing metals and from the light emitted by burning chemical compounds. Chemical reactions propel them and burst them into special shapes.
The simple chemical reaction that occurs in fireworks is combustion

For the answer, see the link below (its a fun page).
Fireworks - as the name implies - involve "fire", which is a chemical reaction (normally an oxidation reaction although there are some instances of explosive decomposition).
To make a firework work the chemicals have to react to each other.
Yes, fireworks involve oxidation reactions.
Burning and thermal decomposition are chemical changes.
Oxidation.
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
The three types of chemical reactions are: synthesis, decomposition, and replacement.
Metabolism and/or catabolism.
Exploding fireworks is the result of chemical reactions.
No. Fireworks are an example of a chemical change called combustion.
Explosions are a form of either combustion or decomposition (or both) reactions, and they are chemical changes.
After the fuse has been burned
Fireworks and wood burning are good examples of fast chemical reactions =]
The principle is based on chemical reactions.
chemical equations
yes, shooting off fireworks is a chemical change because decomposition reactions occur and the nature of the initial chemicals is changed.
Well you put different metals inside the fireworks, and the cemical chemical reactions make it different colours. For example; copper makes green.
Chemical equations are representative for chemical reactions.
The energy transformation during fireworks show are, fireworks convert chemical energy into light and sound energy.
well to be honest i don't no
