What's Happening in an Explosion?

Gunpowder, charcoal, sulphur and potassium nitrate. Now, why does that light up? Whyre does that explode? And so what's happening any time you have an explosion is just a rapid release of energy. One shell of exploding material then sets off the next one. It's sort of just like fire in the sense i like the way one piece of wood ignites the next piece. So here, its an exo thermic reaction, and is called a redox reaction because it reacts with some oxcident. Often thats atmospheric oxygen. Like fire needs oxygen. It's part of the chemical process to release the energy that's bound inside the wood. Here, you
