Lab video below: Black powder is a mixture of charcoal (C), potassium nitrate (KNO3), and sulfur (S). The charcoal does the 'burning', the nitrate supplies the oxygen, and the sulfur binds it together to make it burn quickly.
Black Powder lab
We will make a small quantity of black powder. The homework builds off of this lab.
This lab and its writeup demonstrates virtually everything we are learning about reactions and thermodynamics:
