Yes it gets heavier. You have iron combining with oxygen from the atmosphere to form a new compound, iron oxide. Unless there is smoke and vapor and ashes leaving the fire, nothing is lost, only gained. Daryl
Burning metal, leaving a solid oxide and no gases emitted. With a much more primitive set of scales, this was the experiment that led early chemists to doubt the phlogiston theory and discover oxygen - although the first discoverer, Priestly, called it "dephlogistonated air". His logic:
1. The most common flammable substances (wood, oil, wax, etc.) burn away leaving ashes that are much lighter than the original fuel.
2. So there must be a substance that makes up most of all types of fuel and turns to gas when burned. Call it phlogiston.
3. If the fire is enclosed, it eventually dies out. The air must have absorbed all the phlogiston it could.
4. Priestley discovered a chemical reaction that produced a gas that would make a fire burn brighter and faster, so he figured that this was air without any phlogiston.
But it was difficult to account for metals that increased mass when they burned. Eventually someone thought up an alternate hypothesis - that burning metals absorbed a gas from the air, and that this gas was also necessary for other combustion. Call it oxygen - and Priestley had discovered how to make it in a nearly pure form, without understanding what he had. That still required an explanation for the fuels that lose mass when they burn, but explaining that wood and oil contained various elements that turned to gas when combined with oxygen was simpler than explaining the burned metal experiment with phlogiston. Other experimenters trapped the air over a wood or oil fire and found an increased content of water vapor and (eventually) carbon dioxide.
But he already had the door open before he started to break it. That's just a temper tantrum from someone much too big for it. He'd make an even worse cop than the cowards of Uvalde.

ReplyDeleteRampage, if memory serves.
DeleteWhy police need to be able to use choke holds. You handle that kind of rage!!!
Delete#3 gets heavier as it burns?
ReplyDeleteI was thinking the same thing.....seems counterintuitive to me.

Makes sense, actually. Burning means oxygen is combining with the iron, adding its weight to the residue.
DeleteThanks! It's appreciated.

ReplyDeleteWhy was he smiling after landing on the seat post? Inquiring minds want to know.
ReplyDelete#5: When you're just DONE with the blue and yellow everywhere.
ReplyDeleteAs the Phlogiston escapes, it gets heavier.

What is going on in 10?
ReplyDeleteMercury thiocyanate burning. Same as the snake fireworks we played with as kids.

Nope. That’s an alien turd.
