What is Gunpowder?
Gunpowder was the first explosive known to man. It is made out of a mixture of sulfur, charcoal, and potassium nitrate otherwise known as saltpeter.

Important Gunpowder Events
The Chemistry of Gunpowder
Gunpowder works because black powder consists of a fuel (the charcoal), an oxidizer (saltpeter), and sulfur, which allows for a stable reaction. The charcoal's carbon mixed with oxygen forms carbon dioxide and energy. This reaction would be pretty slow, sort of like a wood fire, but gunpowder has a oxidizing agent, the saltpeter, which provides extra oxygen.

Early History of Gunpowder
Gunpowder was invented around the late 800s in China and was first used to make fireworks and then weapons. The Song Dynasty of China were the first people known to use a cannon. When the Mongols invaded China, the Chinese and the Mongols were reported to have attacked each other with missiles fired from metal tubes filled with gunpowder.
Fall of Constantinople
After gunpowder was brought from China, the rest of the world began zealously creating new and improved weapons with it.
Saltpeter
Saltpeter or Potassium nitrate is a substance that is used today in fertilizers, rocket propellants, and fireworks, as well as being one of the major components in gunpowder.
Chemical formula: KNO3
Chemical equation when ignited.

6 KNO3 + C7H4O + 2 S -->→ K2CO3 + K2SO4 + K2S + 4 CO2 + 2 CO + 2 H2O + 3 N2

From now on, the sound is a little faint, so please turn up your volume! Sorry about this!

Main instigators of the Gunpowder Plot
Chemical equation: KNO3 + C7H4O + S
Gunpowder was invented around the late 800s, not 1800s as I said on this slide.
