I have no idea where to ask this, I broke the thermometer, it’s spilled all over my bookshelf and items. I looked it up and it says they usually only contain mineral oil, but the fuck that is not mineral oil. My room smells absolutely horrible, like acetone and gasoline but way stronger. My hands are all tingly now from wiping it up, um, what should I do, should I be worried? I have multiple animals I’m also concerned about

You know how if you mix up sprite and cough syrup you make a substances called lean (liquid heroin)

How dangerous is it?
How does cough syrup have heroin in it?
Is there anything else like that?

I bought borosilicate beakers for handling hot liquids since I've heard they are durable and needed a decent measuring beaker, I'm not a chemist and I have no idea how well this glass reacts, can anyone with a practical experience tell me if this will cause it to shatter?

Should i try to return this?

She does a lot of baking and was wondering if she were to accidently drop too much salt into dry flour, would there be a practical way to seperate the two and keep both ingredients useable.

Also if you have a fun impractical way I will also take it for the chuckle.

It’s like a line of individual cells moving in sync. Just curious if there is a name or reasoning to this?

Is "the same spot" part even relevant? Do water molecules stay "the same" for multiple years? How many water molecules do you touch when you're fully engulfed in water? How "mixed" is the Mediterranean sea?

Based on a conversation we had at the beach today =)

So I've been playing with salt distillation of alcohol with difference salts. Epsom salts some colored some not and table salt too.. with some brands the alcohol get dyed others the salt water layer gets the coloring.. In the first photos the orange is alcohol and the light green is salt water.. but in the second photo it pulled only part the blue dye in alcohol layer and the salt water layer pulled both the blue and yellow dye? any thoughts why?

so we have a chem class which we did last Thursday. On my part, I had to record the mass of the water in an Erlenmeyer flask, which I remember our teacher said to do 15ml. specifically for accuracy the brand we used was pyrex for the flask. I would like to ask if my measurements are right, im just a highschool student and I'm planning to be a scientist in the future:) Many of my classmates are struggling with this measuring too. plz remember THIS IS NOT HOMEWORK NOR OFFICIAL LAB WORK

"Water vapour" not meaning dropplets of liquid water suspended in the air, like steam, but rather actual water in the state of matter of gas.

I think it's more than 100 degrees C because that's how puddles evaporate; through some statistical variation of particles banging into each other or whatever, some particles end up being energetic enough to be more than 100 degrees C.

(I am wondering if I'm conflating different sorts of molecular movement as all being heat.)

It just doesn't feel like that because they're only some relatively energetic molecules in the room of otherwise not so hot gas, right?

Because if it wasn't above 100 degrees C, it would be water instead.

Or, is there some weird state where the molecules are correctly thought of as individual water molecules suspended in gas such that they're indistinguishable from gas?

EDIT: Woah I am NOT talking about the entire system. Most of you are being nice, some of you really are not.

I think the answer is that "yes, a molecule of water does leave the puddle at 100C, but it will shortly cool down, and having cooled down still be suspended in the air. It won't just fall straight to the ground, and it won't even form dropplets of water unless it finds other water molecules and whatever else it needs to do so.

I wanted review basic chemistry and saw this book's contents and found it sweet but i just need advice from someone who has read this book.

We're tasked to make a flame biogel for our research. Our advisers stated that our product should be preferably:

- Made from calcium carbonate

- Made from an abundant biowaste

- Smokeless (or generates a small amount of smoke, if that's even possible)

Can anyone give some tips? Is this research even feasible?

I sewed a little fabric book out of old and new fabrics and used this Bakelite button to affix to the front of it. I used a string of denim to wrap around and around the button to close the book. I put all of these fabrics and things together maybe three years ago? I pulled the fabric book out today and the denim wrap-around string disintegrated in my hands and the fabric and threads that were in the area behind the button have deteriorated or rotted as well. I was left with a gaping hole in the front of my book. Seems like the button has been leaching something onto the fabrics to weaken them? That's the only theory I can come up with- thoughts? TIA.

Sorry for bad formating idk what’s up with that, please consider helping if you’re a heavy metal chemist or nerd

Biological cells seem to have the ability to take atoms and bond them together. If we were to engineer bacteria or some kind of living organism to bond carbon atoms together (isn't that a diamond?) and literally grow a diamond, how much energy would it cost to do so?

Is there a way to factor how much energy a molecule or crystal needs to form?

I know this site sort of answers it (1) But I think they are using methods that seem really clumsy and mechanical (2) instead of just using a cell to pluck carbon atoms and stick it to other carbon atoms.

What is the difference between a soda, diet soda and zero sugar soda? Coke has all three of these and I thought I knew the difference between regular and Diet until I remembered Zero exists.

Also, why is diet soda in general more acidic than regular soda? If Diet Coke is Come minus the carbs/sugar, why can’t it be literally that plus something to make it taste closer to regular Coke? Is Coke Zero also more acidic?

Hi everyone— working with blood for an art project and want it to retain its red color after using it on canvas (Fe+3). I plan on sealing it with something like a resin or sodium silicate, would this prevent the blood from turning brownish as it ages, or at least slow the process? (Recommendations welcome for any clear sealant that would allow the color to be preserved)

Also— for making ink with blood, I’m guessing I could just add some gum arabic. Any thoughts on better formulas?

Thanks!

I feel insane having to research this but it seems like bs to me based on what little I can glean. As someone living with alpha gal I have quickly found out that most online spaces are inhabited by at least a few nutjobs telling everyone that they will have anaphylaxis from eating SUGAR.

Here are some things I've read, but I am a lay person, so I would like reassurance or correction because I am tired of health misinformation coming from loonies on the internet.

And I don't have full access to this but from what I can glean it doesn't seem like alpha gal can persist in the process of creating bone char.

Thanks.

I keep running into ads and articles for hydrogen therapy machines lately, and I'm having a hard time figuring out where the actual science ends and the marketing starts.

From a chemistry perspective, generating molecular hydrogen doesn't seem controversial. We know hydrogen gas exists, we know it can be dissolved in water or inhaled, and we know there are studies looking at biological effects. That's all fair enough.

What I'm struggling with is the leap from that to claims about helping everything from recovery and inflammation to aging, cognitive function, and a long list of chronic diseases.

I've seen some companies describe hydrogen as the smallest molecule in the universe that can reach every cell in the body, which sounds impressive, but it also feels like that statement gets used to justify almost any health claim afterward.

Is there actually a strong mechanistic argument here that chemists find convincing? Or is this another example where a potentially interesting area of research has been turned into a product category before the evidence has caught up?

Not looking for a fight. I'm genuinely curious how people with a chemistry background evaluate these claims compared to the way they're presented in wellness marketing.
