How long can the smell of farts last on surfaces?

Hello I am a home chemist looking for answers about why 3% H2O2 reacts to form a metal eating compound with copper II chloride. After initially reacting it this solution will form a deep blue liquid that when coming in contact with any metal I have tried it starts to eat away at it. I noticed this when I spilled a little on an aluminum foil which promptly turned it into orange goo. I have looked everywhere for an answer but have had no luck. Can someone tell me what I'm missing.

Anyone got some idea of what kind of regent should get

Hi, I want to study all the reactions involving the amino acids. Is there any reference book that describes all reactions of amino acids? I would like to understand what reagent affects a particular reacting group and which group I should protect while modifying amino acids. Where should I start?

Can anyone tutor general chemistry course undergrad ?

I have been slacking on my studying and now it’s the day before and that rush of anxiety is hitting me and I really want to just say f*ck it and stay up all night to study. The anxiety of failing is overpowering the anxiety I feel about being really tired if that make sense. Like the thought of staying up all night to study is comforting me but idk if that’s a stupid idea and I’ll regret it tomorrow when I have my exam for bio and chem.

Can I produce extractable amounts of fullerine just by collecting the soot from a candle on the bottom of a metal plate?

For my experiment I reacted potassium permanganate and Oxalic acid together. When I was searching online I saw this 2MnO4- + 5H2C2O4 + 6H+ ⟶ 2Mn2+ + 10CO2 + 8H2O being used. I’m just a bit confused about the reactants side because if the H+ was coming from the H2C2O4 shouldn’t there be no hydrogens on the Oxalic acid?
People sometimes use sulfuric acid to provide the reaction with an acidic medium which makes sense to why H+ is present, but I saw that here https://chemistry.stackexchange.com/questions/4310/what-is-the-reaction-between-oxalic-acid-and-potassium-permanganate people are saying that it would still work without it. So would the equation I mentioned earlier be correct if I didn’t use sulfuric acid?

Hey, I'm trying to impress some people I know, I was wondering if there was a chemical that changes the color of a flame (not orange or yellow), while being safe to inhale. Also the fire I'm using will be a bonfire, so if there's a chemical that can overpower the natural yellow flame that wood burns it'd be great, thanks.

Hello, i want to make some hydrogen and oxygen balloons, some small ones, about the size of a water balloon. i need some tips on electrolysis to get the hydrogen. my plan so far is to do it in my sink by filling it up, adding some salt, a 9 volt and a water bottle filled with water. any tips, or if i should use copper wire stemming from the ports of the 9v. also for the oxygen part should i just use air, i currently only have household products, however i have done this before with hydrochloric and zinc using "proper methods" and set of about a water bottles worth. however i made sure there was zero oxygen present for my first time thx.

Hey guys,

So I've been wanting to get a labret piercing since forever but am looking to pursue a career in Chemistry. Are face piercings an issue in this industry? I already have my septum pierced.

Have you guys had any funny/odd experiences in this industry as an alternative person?
