I found an oxidizer pool pad in my grandmas back yard I thought it would smell like chlorine I inhaled it only once and it was like a big box but there is only like a few of them in there I can still breathe but I don't know if it's going to kill me or not

Can you go over the difference between Cryogenic and Non cryogenic next time.
@DrBruckVU
@DrBruckVU 3 года назад
Cryogenics rarely have much to do with oxidizers. The primary dangers with cryogenic materials are the fast vaporization that they undergo as they come up to the external temperature and the flash freezing that results from direct contact with them. I talk briefly about cryogenics at the end of this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QDU71YrmRDo.html, but it isn't discussed too much more in the course that these videos are generated from.

@@DrBruckVU Oh okay thanks a lot! I'm in 8th grade and trying to learn somethings about rockets, fuel, and oxidizers.

@@cxsmoswrld4257 Very cool! Cryogens are used in certain types of rockets because you can pack more material into a smaller space by liquefying it and it will stand up to the extreme temperatures of space. Liquid oxygen (or other liquids that decompose into oxygen) are commonly used as oxidizers in those scenarios.

@9:00 the slide says that an oxidizer is a substance that donates oxygen to the fuel, but in the next slide MnO2 which donates an oxygen is a reducer? Isn’t a reducer something that reduces, not something that is reduced? Shouldn’t it be that an oxidizer is reduced when it oxidizes and a reducer is oxydized when it reduces?
@DrBruckVU
@DrBruckVU 10 месяцев назад
Yes, that's a mistake. I intended to say that the MnO2 was reduced, not a reducer (the slide is correct, I contradicted it in my voiceover). Thank you for the correction. 👍

You are correct - the textbook edition we use has not yet updated to this newer placard. Thanks for the insight!
