Marcade posted:Reminds me of a radio ad for 30% vinegar which claimed it "didn't contain any harsh chemicals". Aside from, ya know, 30% acetic acid. Uh, wouldn't "30% vinegar" be a 30/70 mix of 5% acetic acid, aka 1.5% acetic acid?

Vinegar has its own special scale, grains, where grains refers to the mass of sodium hydroxide required to neutralize vinegar of a given concentration. 50 grain vinegar is roughly 5% acetic acid.The Lone Badger posted:I mean if you really want to know just titrate it. yep! exactly

Platystemon posted:Shrinkflation has hit household vinegar. There was major backlash against this because a lot of people rely on the vinegar being 5% to safely preserve food. Diluting the vinegar you manufacture could actually kill people.

The worst outcomes on the chubbyemu videos are always where the patient can't or won't tell the doctors what they did. Because some of this organic chemistry poo poo is easy to treat if you know what it is and get to it fast enough, but if you won't tell your doctor you've been spraying your balls with pesticide there's not much he can do except make wild guesses as to what's wrong with you based on your symptoms and he's not going to guess "sprayed my balls with RoundUp".

Soon uh... If that chart is right, max impulse is at an O/F ratio of 0.7. Is that mol ratio? So 0.7 moles of F2 with 1 mole HCN. If it's all gas coming out (4000K lol ya) 0.7 F2 + HCN ---> x HF + stuff Assume all the H runs off with F. Most of the N go to N2 maybe? And some carbon (black smoke)? The hot HF is going to MURDER your combustion chamber, and I suspect hot CN- isn't nice. Plus if it's not cryogenic you're not getting regenerative cooling for your 4000K reaction so what the hell are you able to use.... HF 1 mole N2 0.5 mol A mole of carbon and 0.4 moles F... That'll make a mess of fluorocarbons This is just handwaving...

That's a substantially worse isp than most hydrolox vacuum engines, which is used for pretty much every upper stage currently in use.
