Thanks for listening!
decomposition to produce oxygen!
synthesis to produce hot gases!
DO YOU LIKE FIREWORKS?
LETS TALK MORE ABOUT FIREWORKS
hold mixture together and separate elements
help strengthen the colour
Ammonium perchlorate is the most common
used for shooting the aerial shell
The hot gases released add to the
of the reactions
produce color by luminescence
filled with gunpowder, stars, and a time fuse is placed in a
gunpowder in the shell
later in the sky and produces
The fuel gets ignited and allows the stars to burn.
Time to learn about the equations!!
Fireworks originated in
~2,000 years ago. Legend has it that fireworks were discovered invented by
by a Chinese cook working in a field kitchen who happened to mix
It went boom!! and there were many colours that he found pretty.
YEAH YOU DO!!! Here's some brief history
A solid fact is that the Chinese did invent
though, in the 9th century, and it is a very important part of fireworks.
