Hi, Please help! My son is in the 6th grade and has an idea for a science project, and I need to know the why's to our project. The project is: We take a...
I suggest that salt (sodium chloride, NaCl) does no good. Vinegar is a 5% solution of acetic acid (HC2H3O2) in water. Acids react with bases (alkalies). The...
write to the maker of the ornament asking what is the source/composition of this silver paint source [you could buy some] it and test eg its pH with litmus...
If the ornament has a metallic coating , it dissolves in acetic acid of the vinegar. If it is also dissolving in NaCl, that's a bit of puzzle In that case, it...
There is a rapidshare.com link to it on this page: http://rapidlibrary.com/index.php?q=zubrick Also, it is among the ebooks in the Organic Chemistry folder in...
0.2132g of an unknown amino acid is weighed. Small portions of the sample are added to 0.50 mL of water, with stirring, until no more amino acid dissolves. The...
AIEEE 2009 model paper 2 is uploaded - download it from http://www.scribd.com/doc/10322039/Csir-Ugc-Jrf-Net-Chemistry-Paper-1- Part-b-Series-1 Aditya vardhan ...
I glad to inform you that I have uploaded solved CSIR UGC JRF NET CHEMICAL SCIENCES PAPER-1(PART-B) paper. Also useful for those who are appearing for GATE...
- THEW AMOUNT OF AMINOACID THAT REMAIN DISOLVED IN THE SOLUTION IS: 0.2132 - 0.1849 = 0.0283 g. THE SOLUBILITY WILL BE = 0.0283 g/0.5 mL =0.0566 g/mL. --...
A small sample of an unknown amino acid suspends in (i.e. has the same density as) a solvent made by mixing 0.88mL of dichloromethane with 0.12mL of...
i couldnt download this ebook..... so i request you to mail me.....it will be useful for me ... From: John W <JohnWW@...> Subject: Re: [The Chemistry...
1. Let the 0.1M NaOH solution be called S. Let the 50% NaOH solution be called X. Atomic weights: Na=23 O=16 H=1 NaOH=40 500mLS x 0.1molNaOH/1000mLS x...
Check out my Multiply site I set up a Multiply site with my pictures, videos and blog and I want to add you as my friend so you can see it. First, you need to...
In qualitative organic analysis, sodium fusion converts organic halides to sodium halides, nitrogen to sodium cyanide, and sulfur to sodium sulfide. In...
Final call for papers: BCBGC-09 The 2009 International Conference on Bioinformatics, Computational Biology, Genomics and Chemoinformatics (BCBGC-09)...
That can only be done in the absence of oxygen and nitrogen and other reactive gases, i.e. only in an atmosphere of argon or helium or other inert gas.آ John...
A TLC experiment is peformed. When the solvent advances up the plate by a distance of 4.20 cm, it is found that substance X moves up the TLC plate a distance...
Suppose you have a mixture of the following solids: iodine, benzophenone, benzoic acid, and oxalic acid. You dissolve a small quantity of the solid mixture in...
I'll give you the answer tomorrow, unless someone else beats me to it. In the meantime, why don't you pick up an organic chemistry (lab) book? ... From:...
