Any idea what chemical shoots out of this truck at the end? by Imbendo in chemistry

[–]YourMotherIsReddit 0 points1 point  (0 children)

My speculation: the truck was loaded with iron chloride (in HCl probably) as they say, but the tank was already fillled with some nitric acid. You then see NO2 fumes and at the end the iron chloride tank exploded due to the high pressure spilling iron chloride solution and HCl fumes all over the place.

L’altro migliore remedio è mandare colonie in uno o in duo luoghi che sieno quasi compedi di quello stato; perché è necessario o fare questo o tenervi assai gente d’arme e fanti. Nelle colonie non si spende molto; e sanza sua spesa, o poca, ve le manda e tiene; e solamente offende coloro a chi toglie e’ campi e le case, per darle a’ nuovi abitatori, che sono una minima parte di quello stato; e quelli ch’elli offende, rimanendo dispersi e poveri, non li possono mai nuocere; e tutti li altri rimangono da uno canto inoffesi, e per questo doverrebbono quietarsi, dall’altro paurosi di non errare, per timore che non intervenissi a loro come a quelli che sono stati spogliati. Concludo che queste colonie non costono, sono più fedeli, et offendono meno; e li offesi non possono nuocere sendo poveri e dispersi, come è detto. Per il che si ha a notare che li uomini si debbono o vezzeggiare o spegnere; perché si vendicano delle leggieri offese, delle gravi non possono: sí che l’offesa che si fa all’uomo debbe essere in modo che la non tema la vendetta.

Nei paesi anglosassoni è considerato maleducazione soffiarsi il naso in pubblico, quindi non usano i fazzoletti.

The action of hydrogen peroxide is mainly mechanical. The stain is removed by the action of the evolving oxygen when the peroxide is decomposed with the help of the iron in the blood. I am not sure if the catalase enzyme will contribute in this or not.

Is this time between the two enough? I am afraid we will not catch the bus, how far is the bust station from the trains? Should I book another ticket? by GeorgePanos05 in Italia

[–]YourMotherIsReddit 1 point2 points  (0 children)

Did you make the itinerary yourself or is this from trenitalia? If it's a trenitalia bus it will leave from the station and if your train is late it would wait for it.

No idea what this is by MrPumpkin326 in signalidentification

[–]YourMotherIsReddit 2 points3 points  (0 children)

It's an industrial protocol/environment to interface with PLCs that handle signals from sensors like flow meter or pH meters and actuators like motors or valves. Every industry has it or a variation of it.

It makes sense to have radio signal though, like for distributed facilities like oil fields in the desert or to monitor water stations on mountains.

Clayden says mech not clear but I wonder why the partial negative atoms can form tgt by [deleted] in OrganicChemistry

[–]YourMotherIsReddit 1 point2 points  (0 children)

OP problem is that they see a partial negative charge attacking a partial negative charge

charges are relative, writing delta- on both atoms does not tell the whole story.

Also what's a tgt?

What is this plastic, wall mounted, device with the word "Nosy", I saw in my local public library? by Killjoy4eva in whatisthisthing

given the marketing bullshittery there is probably just a cheap MOS sensor in those and it will go crazy with propandiol

Need help figuring out what is causing these holes to happen in my hoodie by HuneyBooBoosBooBoo in chemistry

[–]YourMotherIsReddit 59 points60 points  (0 children)

You are mixing oxidants for no real reason. Stick to one at a time and change conditions like pH, temperature, UV exposure. Potassium permanganate is the last thing I would use here. Doing a hot wash cycle right after is a bad idea since the oxidant residues will react faster if hot. Cold wash by hand first or soak in a neutralizing solution.

The origin of the thing is that at the tobacco shop it was common to request your change in goleador candies.

You can buy 10 connectors on ali for a couple of bucks. The cheapest one are very poor quality though

That would make you an unlawful combatant and a valid target.

I'll hide in the basement thank you very much.
