as a special branch of chemistry i.e. organic chemistry. In organic chemistry we study millions of hydrocarbons i.e. the compounds formed by the combination of C and H atoms. And this combination capability of the C is due to its valency or the number of valence electrons present in the...

I'm an electronics engineer, not a chemist. I'm translating a French chemistry based patent into English. Reference is made to hydrocarbon compounds, or example: un composé hydrocarboné en C2 à C10, de préférence en C2-C8 Is this written in English as, ' ... a hydrocarbon compound ...
If you've studied chemistry at some point in your life then the chances are that you've been asked to memorize at least some of the periodic table by an old, grumpy teacher. While memorising the elements can seem like a bit of a pointless exercise to weary students (why can't you jus...
How to achieve a uniform mix of HETEROGENEOUS compounds? « on: September 04, 2017, 04:19:06 PM » I have liquid PMMA and a solid powder. I want to disperse the powder particles in the PMMA uniformly into a solid block. So while the PMMA is still in liquid form, I pour in the...
Fully automating the evaluation of drug compounds To aid chemists in evaluating whether compounds have desirable physico-chemical properties, a KNIME workflow was developed that that routinely updates compounds registered in the proprietary database, with the corresponding predicted phys...
Apparently we are in the “Aluminum Age” and it’s everywhere, but so unhealthy according to Dr. Christopher Exley, Professor of Bioinorganic Chemistry at Keele University in the UK. Chemtrails Are Polluting Our Environment The reality is, this “toxic cloud shield” created by aerosolizing the...
compounds of sodium and potassium. Wikipedia isn't a bad place to look, if your textbook is lacking. You'll see, all simple compounds of sodium and potassium are soluble. And for that reason, we use them preferentially, in high school chemistry courses, in industry, in analytical chemistry...
Polyatomic anions sometimes gain one or more H+ions to form anions of a lower charge. These ions are named by adding the word hydrogen or dihydrogen in front of the name of the anion. It is still common to see and use the older naming convention in which the prefixbi-is used to indic...
" says Giulia Menichetti, an associate research scientist at Northeastern's Center for Complex Network Research. "Looking at databases that are available worldwide, we have between 20 and 30 thousand different chemical compounds in our food. And that's just an initial estimation."...
