Transcript of Copy of Chemistry of FIREWORKS!!!

The Chemistry of Fireworks!! Fireworks are believed to have originated from China (Bradley par 1)

A alchemist accidentally discovered black powder, by mixing sulfur, saltpeter and charcoal and realizing that this combination was explosive and flammable (Shakhashiri par 24).

This black powder was placed in the bamboo, launched in the skies and became known as the first fireworks (Baxamusa par 3).

acepyro.com There are 6 components that make up a firework:
(Gondhia par 1) OXIDIZING AGENT BINDERS FUEL REDUCING AGENT REGULATOR COLORING AGENT They hold the mixture of the fireworks together

They do not begin to work until the firework has been lit

Example: Dextrin (a starch)

(Gondhia par 13) Causes the redox reaction to occur

ex. charcoal, black powder, etc.
(Gondhia par 2)

The redox reaction occurs in the mixture

of an oxidizer and a reducer ( "What Simple Chemical Reaction Occurs in Fireworks?." par 1) An element that produces oxygen in the reaction

The oxygen is needed in order for the mixture inside the firework to burn

("What Simple Chemical Reaction Occurs in Fireworks?." par 2) They burn the oxygen to produce hot gases
(Gondhia par 8). Are metals that are used to control the
speed of the combustion or the
reaction in the fireworks
(McCallum, Smith par 7). Different chemicals are used to produce different colored fireworks (Gondhia par 10) The greater the surface area
of the metal the faster the
reaction occurs (Collision Theory)
("The Chemistry of Fireworks." par 18). (Gondhia) (Pyrouniverse) Questions? ? ? ? ? ? ? ? ? ? Conclusion: Fireworks today are a big part
of celebrations such as the
fourth of July and New Years Chemists are doing researches to create
environment friendly fireworks (Shakhashiri, par 27) Introduction/ Purpose: This presentation is about fireworks and the components that make up a firework It is related to chemistry because fireworks relies on the principals of combustion, redox reactions and the exitement of electrons. (Gondhia par 1) There is a lot of chemistry involved in fireworks, from the combustion of the fuel to exciting electrons to create those brilliant colors that we see in the skies. Summary "What Simple Chemical Reaction Occurs in Fireworks?." By: Simone Cooper (Shakhashiri par 14)
