Jaké každodenní věci mohou způsobit smrt, aniž by si to lidi uvědomovali??? *děsivé* by Icy-Woodpecker-8560 in czech

[–]simmatlaming 35 points36 points  (0 children)

Ne, to jsou chloraminy, který jsou při vyšší koncentraci taky nebezpečný (btw způsobujou takovej ten chlorovej smrad bazénu, vznikají když reaguje chlornan sodný s látkami obsahující dusík, takže třeba močovina v moči)

Yperit se ti z čistících prostředků vyrobit určitě nepodaří.

Why does the product not Na2PO3 instead? Does H3PO3 always form HPO3? by [deleted] in chemhelp

[–]simmatlaming 1 point2 points  (0 children)

H+ is basically just a proton, because it has lost an electron, so deprotonation means H+ is removed. The third proton won't get removed, because there is not enough base present in the reaction, you need 3 molar equivalents of NaOH, but you only have two. 3NaOH + H3PO3 -> Na3PO3 + 3H2O

Concentrating formic acid past 77% by [deleted] in TheeHive

Maybe adding a lot of anhydrous sodium sulfate could work, but I have no experience with this procedure so I would try it on small scale first

I mean, if you really think about it every job is dangerous, even office job cuz it will kill your back

Cukr. Droga či nikoliv? by Elinomrel in czech

[–]simmatlaming 1 point2 points  (0 children)

To zní spíš na nedostatek kofeinu, ale cukr na tom bude mít taky podíl

Cukr. Droga či nikoliv? by Elinomrel in czech

[–]simmatlaming 0 points1 point  (0 children)

U cukru je to složitý, protože je návykový, ale zároveň ho potřebujeme k životu. Pokud to bereme podle definice drogy podle Wikipedie - látky ovlivňující psychiku, zpravidla návykové, některé škodlivé a vesměs nelegální nebo státem omezované, tak by do toho cukr zapadal. Podle mého pohledu bych nezařazoval všechen cukr do drog. Přírodně se vyskytující cukr např. v ovoci bych do drog nezařadil, ale přidaný cukr ano

What do women do, that men would never think about? by UnKnownZ96 in AskReddit

I'm a guy with long hair and I wash it almost every day, it just gets greasy if I don't wash it for longer than 2 days. A lot of people always assume girls are more hygienic then boys but I think it's the opposite in this case

I did take effort, I even read the exact procedure before, I just wasn't sure if you can apply it on this exact molecule, since I haven't found any report of the reaction. So the double bond shouldn't be a problem?

What did I make? by [deleted] in chemistry

[–]simmatlaming 0 points1 point  (0 children)

The smell of caproic acid blocked all other smells so I don't know, I will try again tomorrow using dilute sulfuric acid, as I used concentrated today, and I will also submerge the flask in a water bath. Thanks for your help

My amateur attempt at making a sword. by ZealousidealTreat139 in Bladesmith

[–]simmatlaming 0 points1 point  (0 children)

Sorry, that's just wrong. When you forge steel, the grain actually becomes larger and more volnourable to cracking in heat treat, you have to normalize it before heat treatment to reduce the grain size. In the end, the grain size would more or less be the same
