daer Friends. This has been bugging me for sometime; it is said that when elements react to form compounds or different compounds react to form some other...
H2N-CH2-COO- + 2H+ ===> (+)H3N-CH2-COOH Atomic weights: C=12 H=1 O=16 N=14 C2H4O2N=74 (for glycinate anion) Let glycine be called Gly. Let the HCl solution...
hello I am from Iraq I prepared some complexes . Can any one help me to measur a sigle crystals and please how much the money for each analysis Regards to...
Some crystals are cubic and some are long and thin. To measure the thickness of a crystal, you can use a micrometer which is easy to buy for $15 in a large...
Hello, Does someone ask: what's happened when the potential difference between electrodes in a electrolytic cell is lower then that necessary for electrodes...
Dear Brian Jensen Thank you for reply the problem is in the instrument (ligt camera) not found in Iraq I asket to help me to the measure the sample . ...
hi guyz, i've posted two questions but didnt get any reply what so ever.Hopefully i wont be ignored now. Q No.1. in percentage composition the percentage of...
Greetings Carbon adsorbs,so if we make fine powder and add it in our diet would it have any harmfull effects? Usefull effect could be that it comes out of your...
Glycine zwitterion structure is H3N-CH-COO (without charges). You expect to have 2 peaks. However H atoms bind to N will be downfield, below 10. The spectra...
Ludwig, that's crap. True, it's most likely that it will be in the zwitterion form. But the solvent is also very important. Glycine as such (and free...
All of the repliers to this question are right. Every one gets a prize. The replier who posted a Japanese web site giving the actual spectrum (one peak) was...
hi,i dont know why I'm not getting any reply for my questions,is it my i.d or my nick that u Guys dont like.Anyway in continuation of my unanswered questions...
Some of us are so busy ... Anyway, the chlorine radical is very reactive since it will easily pick up an electron from nearby molecules. If the only molecule...
Hi, Carbon powder, as carbon black, absorbs very little odor. Activated charcoal will absorb a lot of odors. Unfortunately, it will also absorb water, which...
Hi, The percent composition of the material is determined since some compounds look very similar to another compound. When the percent composition is found,...
I'm a chemical engineer weak in organic chemistry so maybe there is a better answer. The molecule is too small to see. To prove there are 3 double bonds,...
I'm surprised to read that activated carbon has more surface than carbon powder. Activated carbon 500 M^2 per gram Carbon powder has 20 nanometer diameter...
Please: 1) let me know ehre i can find in the internet exercises and problems reoslve on aplication of vande der waals equation (real gases)-calculation of...
hi can anybody tell me how to find outexact bond energies by any software like chemultra or mopac etc. arslan [Non-text portions of this message have...
It was found that 19.60 mL of NaOH solution were required to neutralize 10.00 mL of HCl. if the concentration of the base solution was 0.1051 M, calculate the...
Help me calculate the volume of 19.1 M NaOH (50%wt) solution required to prepare 500 mL of 0.1 M NaOH. density of 50% NaOH (wt) solution is about 1.5 g/mL....
