https://www.youtube.com/watch?v=JslxPjrMzqY#t=6m23s This video makes a distinction between liquid CO2 vapour, and CO2 as a gas, in the context of describing both of them coexisting in the same location. Is there any meaningful distinction between the two, or did the video creator just misspeak?

I really want to learn more about this I am about to stat Highschool and am doing certain categories of higher level learning and want to know how to advance in this subject So please teach me what you all know that I can use and how to learn so I can be ready next year

I have a plastic Yeti cooler that has a really bad, lasting smell from dead fish and bait that got left in there for too long. The smell is extremely hard to remove, I’ve tried ozone generator, bleach, baking soda, vinegar, etc. These seemed to help a little bit but the smell always comes back. Seems like the smell has seeped into the pours, so I need to somehow get it out of that. Is anybody able to tell me what’s going on here from a chemistry standpoint and is there any hope for salvaging this or should I just pitch and get a new one? (I’d really like to try any route possible to save it as it’s a customized cooler and very expensive)

Is it possible to maintain an environment with low humidity to preserve electronic devices from oxidation without this low humidity drying out plastic and rubber from electronic devices and DVD discs that are plastic and in that environment? in my room I have two digital hygrometers and an air dehumidifier plus 300 with q compressor that stays on all day because the humidity goes up to 70%, while in the dehumidifier the humidity is at 40% in the hygrometers the measurement is at 50% so I set the dehumidifier to 40

Hi all, In short, I'm writing a fantasy novel set 20,000 years in the future, focusing on a group of magical humans who escaped Earth on a colony ship to a planet where they could evade persecution. In the present day they have reverted to a medieval lifestyle but the futuristic element remains, as the rest of the galaxy has been colonised in some form of 'human empire'. There is no contact between the planet and the outside world. Initially I had no connections between the futuristic tech of the 'Earthlings' and the settlers on this planet, then it dawned on me. What happened to the colony ship they originally used to escape Earth? To avoid a p…

I have this salt water car kit in which the power source is 3 components - a magnesium sheet, a "non-woven fabric" and an "air cathode". When I stack these with the fabric in the centre after soaking the fabric with salt water, it generates a potential difference in the whole thing. Can anyone please explain how this happens? I really need a reaction for this and a description would be really nice.

electrolytic capacitors of electronic devices can remain unused for how long so that they do not depolarize and lose capacitance?

Hi, Please share with me all you know about wood material pH!! Do you have any idea about wood material pH and what factors can affect wood material pH. How important you think is wood material pH for real life applications? Also could you advise best instrument to measure wood material surface pH I am interested in wood types: birch, alder and aspen and what affects their pH. Please find attached the kind of veneer I have in mind for example to test pH

I have a PS2 Slim 90000 and its case is ABS plastic and it has rubber parts, this device is located on a wooden table, the lights with UV in my house and the sunlight coming into the house will dry out, crack and damage the ABS plastic and the rubber of this device? my house uses LED bulb

Doubt about humidity and oxidation, I don't live near the beach and I keep electronic devices inside cardboard boxes and in an open anti-static bag, an air dehumidifying device that uses a compressor sucks moisture only from the air or sucks moisture inside the boxes and do bags?

Given a volume of hydrogen gas (mixture of protium and deuterium hydrogen), how one might separate this into only protium hydrogen? Knudsen diffusion? (MW1/MW2)^^0.5 MW deuterium (H2) = 4.028 MW protium (H2) = 2.0158 (4.028/2.0158) ^^0.5 = 2^^0.5 = 1.414 Separation factor of 1.41 is possible by diffusing through a membrane.

What material is the plastic market bag made of? does this material retain (hold) moisture in the bag and everything in the bag or around the bag becomes damp? i put some bags inside a cardboard box and inside the cardboard box i also put dvd cases and i am worried if the bags will hold moisture inside the cardboard box and pass moisture to the discs?

Ok. So I learned Methylene Chloride can make a motor https://youtu.be/bY204gZEKtw It needs to be made like this https://photos.app.goo.gl/3GPBQCMhPgBrfTzc6 I need the help of some students to speak to companies to make it When I say this alone all companies has refuses to answer I swear to you drug dealers get more respect then me I swear to it Very needed project I can explain more if anyone answers Please reply to me I truly want people to have respectful jobs The Methylene Chloride will make a indoor wind generator

I am confused on how to convert 4.5 nanograms to micrograms per microliter. When I make the conversion do I have to use any calculations to get microliters. Using the fact that there are 1 x 10^-3 micrograms in 1 nanometer I get 4.5 x 10^-3 micrograms per microliter. Is this the correct answer? Any assistance from anyone would be greatly appreciated!!!!

Newbie here, looking for answers to two questions relating to frozen chips, and hoping this is not too mundane, but it has puzzled me and can only think there must be scientific reasons. Quick background - I was weighing a portion of McCains frozen oven chips to calculate what my calorie intake would be, and am now puzzled 1/. As I was writing down the weight I noticed it went up by 1 gram, so thinking I was going mad, and watched them on the scales a bit longer, only to see the weight going up by 1 gram about every 10 seconds, which I thought was crazy. So please, what is causing that? 2/. I noticed on the bag of chips it stated that the calories per 100g…

I encountered catalytic hydrogenation recation, where alkene is converted into alkane using Pt/C or Pd/C as catalyst, but I have a question: Bond dissociation energy of H2 = 436kJ/mol. But when H2 is adsorbed on the metal surface, the bond is broken. How come this simple step can break this strong bond? Where does the 436kJ energy come from / what gives this activation energy?

According to my knowledge, negative deviation of the Law is because: - solute-solvent intermolecular attraction is larger in magnitude than both solute-solute & solvent-solvent interactions, so solution reaction is exothermic. With very strong interactions, molecules become less able to escape from the liquid surface and form vapor, hence a lower vapor pressure than Raoult's Law prediction. My question: In terms of intermolecular adhesive force(PE), the above explanation is true. However, the reaction is exothermic (since dH(soln) is negative usually), meaning heat is given out. This increased temperature of the solution hence the KE of molecules. According …

Hi i am not sure if this the Right Place to post i hope if anyone can help me plastic deformed when trying to clean it with gasoline with octane number 95 I thought it would be an alternative to isopropyl alcohol but I think I got it wrong I cleaned an old remote with gasoline I put all the component and I left it for maybe an hour and when I came I found very sticky layer on the top of the plastic and the structure of it changed it's more flexible Spoiler and not only that the buttons have been expanded too. but after an hour it shrank but not to the original size Spoiler i hope if some one …

I am beginning in chemistry I wanna u help to study it.I wanna any books or websites to learn the basis to advanced level of chemistry . I wanna self-teaching because I can not enter the college and I want to teach it step by step and give me the name substance they give in college are all and the name of books in all years and any useful sources can be supported. I wanna u help because I love chemistry. Thank u all.

Hi Everyone Often, when I am looking at Nutrition Facts labels, I find that the totals given for the different types of carbohydrate listed in the carbohydrate section do not fully add up to the total of all carbohydrates. This suggest to me that there are one or more types of carbohydrate which never get listed. Can anyone here therefore tell me if there are any carbohydrates which do not fall under any of the following four categories: Sugars, Fibers, Starches and Polyols. Thank you very much. Kind regards Tim

I want to know a strong chemical , chemical formula or any acide used to quickly dissolve and corrode iron and metal. Thanks

Is it that protons tend to join other H2O molecules rather than forming H402+?

Even if the given compound is chiral (nonsuperimposable), wouldn't it simply depend on perspective whether the compound is levorotary or dextorotary? And for antichiral compounds, enantiomers don't seem to mean much. It was once described to me that the answer has to do with the given compound's ability to refract light, but I never received elaboration on how this works or how it effects stereochemistry. Can someone explain these things?

Direct sunlight usually has a detrimental affect on chemical substances, but I have been reliably informed that the growth of Acetobacter (Mycoderma aceti or "Mother") in Apple Cider Vinegar can be accelerated when exposed to UV light (A/B?). Is there evidence that UV can accelerate Mother growth, and will it damage the nutrients in the acidic vinegar solution ?
