Chemistry

I've been debating doing a personal experiment for a while now and today decided I'm going to try it even though it might be to difficult to do, or even impossible. I want to keep the Details a secret because well, i don't want to be robbed of my idea. I know it sounds funny, but it has happened to me in the past. Experiment: I have an organism, which can live in mammals(humans included), like a hook worm. It can not reproduce inside the body but only through the stool, but what i'm testing is for a chemical it secretes. The worm secretes this chemical that i believe has beneficial aspects to humans but i need to first somehow grow this worm inside a c…

I was triying to figure out why diet coke and mentos mints have a chemical reaction, and if you eat a mentos then drink diet coke will it have the same reaction? And what is it that its only diet and mentos and not other pops? Thanks for my amature question.

Thanks for the help

soo i am looking for some pure paladium a piece about 3 cm long and 1 cm wide and thickness does not matter. any suggestion's on wher i cold find some? thnx

I tried reading an organic chemistry textbook recently and the complexity of it overwhelmed me. Now I'm wondering if it wouldn't make sense to learn chemistry like a language, where the elements are like phonemes or word-fragments that form "words" (i.e. complexes of atoms that build up to more complex configurations to form large molecules)? I can imagine that super-molecules would work this way, building up from multiple layers of sub-molecular structuring processes, but I don't know enough about chemistry to know if I'm right. Could chemistry be learned in this way, e.g. learning basic vocabulary and grammar of simple super-atomic complexes and gradually learning to…

I have no access to laboratory but I am curious to know the result of this experiment which I read in my elder brother's book. EXPERIMENT Step-1 Take about 2g ferrous sulphate crystals in a dry boiling tube. Steo-2 Note the colour of the crystals. Step-3 Heat the boiling tube over the flame. I have figured the equation for this- heat 2FeSO4.7H2O(s) ------------> Fe2O3(s) + So2(g) + SO3(g) I need help to know 1- What is the change in colour after burning? 2- What would be the smell of the vapours?

ive never had a satisfactory description of how fire works. im talking about like wood, or alcohol and the sort.

any processes for removing hydrogen from gas mixtures? gas mixtures of all kinds, if you can then just suggest processes please, doesn't matter if they are specific to certain mixtures of gas or will only work with different things or whatever. thanks in advance

in chemistry when we define a surface, how many molecular layers/ or 'depth' are we talking about.

how could i get some luminol? or any other material that does its work?

so for my science fair, im going to make some c60, and perfect the process (variables volts, amps, vacuum pressure, electrode spacing) but i dont have anything to do with whatever i make, so im happy to sell it! please answer the poll on wether or not your would be interested in buying some of it. oh, and i will separate the graphitic carbon with toluene solution.

so i was thinking about how NaCl is edible and very simple to make. So what i was wondering is if you guys know of any simple synthesis experiments to make edible compounds. Thanks.

what is the equation for the reaction of iron with nitric acid? (and yeah i think it has to be iron filings for it to react significantly)

Hi, We've had this chem assignement at school, and I'm stuck! I've tried everything but it just doesn't work. I don't even think anyone here can help me, but meh, might as well just give it a try. So we have this reaction : 2NH3 ---> N2 + 3H2 So we're asked to find a plausible mechanism (basically invent one!) that can give the following rate law: Rate = k[NH3] / [H2] I've spent about 3 hours trying diffrent mechanisms that take in account the balanced equation, but it never gives the right rate law. For example. I'Ve had this mechanism (the * means radical): NH3] --> NH2* + H* NH2* --> N* + H2 N* + NH3 --> N2H* + H2 N2H* + H* --> …

i got 98% v/v H2SO4 and the density is 1.02g/cm3. how am i able to find the concentration of H2SO4?? and once i find the concentration, how much H2SO4 do i need in 100ml solution of 0.1M? help me thanks.

Has anyone got gabedit 2.3.6 and ORCA 2.8 to work together? If so please let me know how... Gabedit seems to create the input file just fine but when called on ORCA through gabedit it seems to stall...

I was wondering how you get the following: 2.00g H + 2.00g O2 = 1.75g H + 2.25g H2O... and is it the case in ionic reactions, that the closest matching ions within the formula of the reaction will come together, so therefore in a reaction the various ions won't just randomly react with whatever other ion..

I have the stats on a well in a rural area and need to devise a way to make the fluoride level safe to drink. Assume I had to treat 1000 L per day and I wanted to get the fluoride concentration down to 1-2mg/L, how would I do that or show some calculations? the details of the well im focusing on are: pH=7.9 TDS= 975 [F-]= 13.1 mg/L [CO3^2-]= 3.0 mg/L [Ca2+]= 5 mg/L I know I need to precipitate it but im not sure how to show calculations for it or what to use. Any help would be amazing.

my question is; some references state that when NaOH accept proton (H+) became Na+ and H2O and Na+ considered as conjugated acid but some other references state that H2O as conjugated base. please answer my question

i bought some rubidium for my collection and i bought 2 extra 1g ampules to sell or trade to other collectors so if anyone is interested i can sell them for $85 total (all costs are included in the sale price) i take paypal so if anyone is interested let me know. i have all the proper shipping material and information as to what is required to ship this safely i also have some arsenic and other hard to get elements

I am experimenting with hydrogen production like you can commonly see on the internet using a "dry cell" hydrogen generator (or HHO generator). I am wanting to find the best electrolyte for the process. Most people on the internet use Lye, or Sodium Hydroxide, as an electrolyte. However, I am using aluminum plates vice stainless steel as my electrode's due to the relatively affordability and good conductive properties (over stainless). My understanding is that the Lye would prevent the oxidation layer forming on the aluminum and the water would basically eat (oxidize) the aluminum? Ideally I would want a electrolyte that wouldn't leave a large build up in the cell and wou…

Hello everyone, This is an area I don't understand much, so I have some questions. *Uncouplers of oxidative phosphorylation (these are true/false questions) -make respiration uncontrolled (I know it is true an it has something to do with ADP no longer controling respiration , but I really don't understand the question much) -Increase the permeability of the inner mitochondrial membrane to proteins (I'm thinking true. Is this how they disspiate the hydrogen gradient) -Increase respiratory rate (Don't know) Also how does 2,4 DNP acts, does it inihibit a complex, or move hydrogen ions disturbing the gradient? Also more questions -Electrons can be tra…

I know it resembles a phosphate. Did a search it was very vague. Thanks

I am trying to measure zeta potential of my particles wich are silicate based, the zeta potential is decreasing with time, in 1mM buffer, it starts with a positive 10 value and decreases to about -30 over 30 minutes. Is this a stability problem?

Even after twenty years of use most quarters have the same shiny appearance that they did when they were minted. Most pennies, however, have dulled considerably. What does this suggest about the position of the metal used to make quarters and the metal used to make pennies on the activity series? *Talking about quarters and pennies from 1997* Over time pennies get dull because of their composition since they are made purely made from copper and as a result copper reacts with oxygen and other gases in the air and therefore lose their shininess as copper reacts with oxygen in the air to make copper oxide and therefore turn dull however, (I am having trouble why quart…
