Specific Chemical Reactions Involved
Fire works are usually made up of, an oxidizing agent, a reducing agent, a coloring agent, binders and regulators. Its when these mix together, you have your Firework.
So the main "oxidizers" would be: Nitrates(*most common*), Chlorates or Perchlorates. (these produce the oxygen to burn ans mix.
The reducing Agent: Sulfur and Carbon. React with the oxygen to form Sulfur Dioxide and Carbon Dioxide.
Binders: This is the last element needed and it is a star. It's really just a lump that holds the star together.
Where we Find the Reactants
We find the reactants from earth.
What Happens to the Products/Byproducts
The firework than explodes. And people enjoy it.
What are the Environmental impacts of the previous findings?
There could be unexpected explosions causing some damage. Air pollution. Some wast is produced by fireworks. And it can pollute other environmental things. Indirectly tho, by eoil erosion, in the soil, fireworks over water, etc.
Are Reactions endo- or exothermic?
Because the explosion is an oxidation reaction, it makes a large amount of hot gases in very short periods of time. This would make a firework exothermic.
Who is affected by this Chemistry!?
Almost everyone is affected by Fireworks, because they are displayed around the world! In America specifically on 4th of July!
How essential is the Chemistry?
To us as people, some countries do find fireworks essential. They have used them forever and don't intend on stopping now.
As for the actual firework, yes everything in the firework is crucial to have in order to make it work.
Interesting Info. !
One interesting fact about chemistry in fireworks is, that some of the firework colors are safer than others. Only because you can get the gold and silver colors from by heating charcoal or metal. You have to burn metal salts to get any of the other colors.
