Today I received an results that leave me completely perplexed. Two samples of waste water were sampled and tested, one without processing and the other run for seven days through a bio beads and actively aerated. I fail to understand the results.

Hello! I am trying to find the grades of xylene and the basic difference between these grades such as isomer grade, regent grade, technical grade. Kindly help me on this. It will be a great help! Regards Saba

Hello, I have a question that I have been searching but haven't been able to find a comprehensive and scientifically accurate answer. I hope the experts on this forum can help me Q. Is Natural Gas included in Petroleum Products. If not how we can differentiate on scientific basis ? If possible please provide references. Thanks

Hey guys, I am working on a project which contains synthensis of compounds on pictre, and I have huge trouble in quaternization od imidazole and benzimidazole rings, so I was wondering if maybe some of you have experience in that part od organic synthesis? I need a good condition for quaternization. I have tried with MeI in acetone for 24 hours in dark and it doesent seem to be working :S

Hi, What symbol do you use for a radical species? You know, that dot that's larger than a period and smaller than a bullet?

Hi all I have to answer a question and I could not find much information so I have come here to be saved. The integral value of a proton signal is the same as the no. of protons that give that signal, but what other factors influence signal intensity? and how can these factors be take into account in nmr measurements? Would I be right in saying background noise is a factor? Is that correct and if so is that the only factor? Many thanks guys jack

What is the best and easiest way to do this with relatively high yields?

I have a few homework problems I am stuck on. I am already struggling with the material and trying to teach myself as much as possible, so any help with these 2 questions would greatly appreciated! How would you make the following compounds starting with acetylene. If compound cannot be prepared using this method say so. 1. 4-methyl-2-hexyne 2. 5-methyl-2-hexyne I am using the David Klein Organic Chemistry textbook and I am finding that there are not too many examples like this to guide me and the teacher did do any problems in class, just assigned them.

I will preface this with the fact that I am no chemist. I am currently working on a project to design low cost alternatives to gasoline/diesel for local farms. My primary area of focus at the moment is in ethanol production from "waste" products already being produced on the farm. I have my still designed and built (Yes I'm applying for a small scale ethanol producers permit). The question that I get from every farmer I talk to about implementing the system is first of all inputs, both labor and materials, and the second is whether or not there is a loss of fertility from the process. The things that they would be fermenting are often produce that either didn't sell …

Here is my assignment: Drawresonance structures to show in which position nitrobenzene will nitrate toform dinitrobenzene. I know that nitro groups are meta-directing, so the product will be m-dinitrobenzene. So do you just draw an intermediate carbocation with the charge in the meta position? If that's the case, where is the resonance? Would I show the charge being in the ortho, para, and meta positions but then indicate that the meta position is the most stable and therefore where substitution will occur?? Any advice is helpful, thank you!

For this reaction http://i.imgur.com/Y2Y1c.png?1?5611 We have to show how it occurs and it has to be subsitution because we haven't "learned" elimination yet. By this I mean it is a practice question for a test coming up where elimination will not be tested. I am able to get one of the products, the product where the CH3 group is not inverted but I don't understand how to get the second product where the methyl is inverted. So I tried it again and I am not sure if this is correct but I wrote that the alcohol group on the Carbon that is also attached to a deterium gets protonated by the H3PO4. This makes h2O and h2Po4 and the H2O gets attacked by the nucleo…

HEY, what is the name for H3C? is it negatively charged methane?

Going to be performing this lab experiment next week and I'm trying to figure out the mechanism just for a better understanding. The textbook does not offer a detailed enough mechanism for my liking. Let me explain the procedure and I'll mention my gaps of understanding as I go...First we are mixing acetic acid with sodium dichromate dihydrate. I'm assuming that this activates the dichromate to make it an oxidizing agent, but the transfer of atoms confuses me... Does the acetic acid attract the sodium ions to make the poly atomic ion dichromate cr2o7^2-? In order to do that it must lose a hydrogen, does it lose it to water molecules to form hydronium ions, or just diss…

2-bromocyclohexanol + NaOMe + heat -----> ? I think the product is: 2bromoheptane-O +OHNa I also think its an Sn2 reaction Am I doing this right? EDIT: The question is to find the product and Mechanism of the following compund: 2-Bromocyclohexanol + NaOMe + heat ----> Inthink my answer is wrong bit this is my nswer: 2-Bromoheptane-O + NaOH

I mean, I have never seen water and ethanol separate from an aqueous solution, at room temp, at different concentrations of the ETOH. I thought polarity was the predominant determining factor here. Like likes like. Can a solution of ETOH/H2O separate by "phase separation"? Or is this pseudo science, people? Thanks

How can you distinguish whether molecules are aromatic or antiaromatic? for example: (a) is antiaromatic whereas (e) is aromatic (refer to attach file)

I've been attempting a reaction which involves a substitution to position 2 of the indole ring for melatonin, using l-phenylalanine as the reagent. What would be required to catalyze the reaction?

I've heard a lot about the properties of fullerenes, so could someone please brief me about them and tell me how they can be used to improve our daily lives. And, how come they have not been put to use already ?

hnmr= 1.13 (t, 3H, j=7.6Hz), 2.48 (q, 2H, j=7.5 Hz), 3.99 (s, 3H), 6.28(s,2H), 9.54 (s,2H)

Hi All I'm working on creating a SLA 3D printer at home and have been trying to research information about UV curable resins but haven't managed to find any reliable source. Can anyone point me in the direction of a good book which differentiates the major types of UV curable resins and their properties? Thanks

I isolated a compound from plant source and it is only soluble in hot chloroform with the melting point of 60 degree. I have taken H-NMR and it clearly shows the characteristic peak of -CH2 group @ 1.2 ppm with the integration value of 69 which suggests that it could be fattyacid or hydrocarbon. But C-13 NMR gave relatively less number of peaks that is only 8 peaks in the spectrum. How can I correlate with 8 carbons and more than 70 protons. Please help me through.

Anybody know how I could make at least 10 grams of stearic acid? Somewhere else on this forum it said you could cool vegetable oil and filter it out. Apparently, vegetable oil is 5-ish% stearic acid. Could I make it from vegetable oil? Help would be appreciated.In advance:No, I don't plan to make drugs, bombs, poison, or anything DEA controlled with it.I plan on making non-spiky ferrofluid with it. I'm a boss at making ferrofluid, so all of mine spikes excellently, but now I need some that doesn't. …

Hello Everyone, Really struggling with this question, please help. Have a test very soon. Much appreciated. I have tried. For the last three, iv) benzne+ch3cl/alcl3+benzne? ---can we add a benzene like that? v) benzene+ch3cl/Alcl3+2(KMnO4)- vi) benzene+ch3cl/alcl3+FeBr3/Br2+nBuli/DMF- Thanks in advance.

Hello all, have a question I can't figure out. If I understand correctly, it is dopamine that gives the high that get people addicted to drugs and whatnot. However, is it not also what gives people the high and bliss of falling in love? So my question is: if dopamine produces the same feelings in love and addiction is there really a difference between the two? at the basic level are they the same thing? And also if anyone could just shed light on what those differences might be? And any other info please

Hey everyone, First time posting. I'm a Macromolecular Science & Engineering student and I've been assigned a paper. I'm just wondering if anyone has any insight on where to find scientific articles regarding the characterization of gels, specifically NMR, IR, and Light Scattering spectroscopy. I'm new to this whole scientific paper scene, so any help is much appreciated! Thanks! Anthony
