I watched a YouTube video of a guy that extracted the potassium from a shitload of bananas, resulting in a big chunk (30 grams maybe?) of potassium that he then threw into a lake. POW! SIZZZZZZZLE POW! This got me to wondering how potassium stacks up against modern smokeless powder. Also, shout out to YouTube channel Explosions&Fire, which is a dif YouTube channel but seriously awesome and you should go watch it.

So, can potassium replace gunpowder?

i would suggest taking an introductory chemistry course before you finish high school

Introductory chemistry will, at best, teach him to identify an exothermic reaction. He'll need to wait until he gets to P.Chem before they start talking about yields and reaction energy.

It doesn't. If it was practical, the military would be using it already.
t. I hand load my own ammo.

Chemistry noob here, how can I self-teach chemistry? I basically know nothing and didn't take chemistry in high school. What resources do you suggest, what kind of learning path I should follow etc.?

Grab any Intro to Chemistry book to learn how to read the periodic table, the basics of chemical bonding, and stoichiometry. Then hit up a book on Organic Chemistry to learn a bunch of inane vocabulary but also chemical structures and reaction mechanisms. Then check out a book on Physical Chemistry to learn the rest. Quantitative Chemistry can be skipped if you're not too interested in actually working in a lab or quality-controlling anything. Inorganic Chemistry can be skipped if you're not trying to manufacture silicon wafers or make emeralds in your garage.
You really only need Chemistry 101 and Organic Chemistry 1 to understand the gist of things.
Khan Academy looks like it has a good mix of the basics, as well as the fundamentals of the other mentioned subjects: https://www.khanacademy.org/science/chemistry

Just start from the top. The Acid/Base/Titration/Buff sections are Quantitative Chemistry; the Thermodynamics and Kinetics sections are Physical Chemistry, and the Redox and Alkane sections are Organic Chemistry. I can't vouch for this program, though, because I haven't looked any farther than this table of contents. At the least, it can serve as a guide and list of concepts to search up and study independently.

Recommending "Chemistry the Central Science" if you want a book
grab a pdf off of libgen.is

No. not only is it not nearly as energetic, but firearms work more on gas expansion than concussive force from ignition/detonation. gunpowder (black powder and modern nitrocellulose and other smokeless powders) work by producing a shitload of gas themselves and building big pressures that way rather than displacing air in exploding.

of course, modern rifles are mostly gas operated and most will fire once but not self-load if fed black powder, and especially so with anything that just explodes rather than producing gas.

furhermore, supersonic muzzle velocities are only possible because the gasses propelling the bullet down the bore have a higher speed of sound in that medium in air. this is why supersonic air rifles are uncommon and usually horribly inaccurate, and why people don't cram tannerite or fuckin C4 into a case rather than nitrocellulose. even exotic caseless ammo is more like firework stars or the stuff found in road flares than being a chunk of high explosive.

Good answer.
Anything that explodes instead of defrags can really destroy the vessel. This is common in a lot of makeshift guns in rural Asia and Africa that poachers use where they grind up priming compounds to substitute gunpowder. Don't do this.
