why aliphatics are also known as parafins?
363973
Some aliphatics are also parafins, but the aliphatics is a much larger category.  An aliphatic molecule is one that contains only carbon and hydrogen.  A parafin contains only carbon and hydrogen, but in biochemical terms it has a certain structure in a repeating pattern.  The parafins and waxes are part of the lipid category in biology.

the higher alkanes, liquid from pentane up, have poisonous effects as solvents. they interfere with the nervous system and can be used to get a "high"

Here is a great site that explains it for pretty much all chemical nomenclature.\nhttp://dbhs.wvusd.k12.ca.us/webdocs/Nomenclature/Nomenclature.html

"Iodine, it is sublime". (Because it sublimates-goes directly from solid to a gas).\n\nGet an "A".

We've to get this clear first. Water is a polar solvent, gasoline is a non-polar solvent. By the principal of like-dissolves-like, polar molecules will dissolve in water, for example, NaCl; while non-polar molecules will dissolve in gasoline, for example, fats, phosholipids, alkanes, alkenes etc.\n\nFor the question you've asked,\nChloroform is a polar compund because Cl draws electrons from the carbon center and making Cl atoms have a higher concerntration of electrons. Hydrogen atoms in water carry a partially positive charge and hence are attracted to Cl molecule. Hence it is soluble in water.\n\nNa2SO4 is soluble in water. This is because it is actually 2 Na+ ions attached to SO4(2-) ions. Na+ ions get attracted to oxygen atoms in water which has a partially negative charge and SO4(2-) ions gets attracted to hydrogen atoms in water which has a partially positive charge.\n\nKCL is soluble in water because Cl atoms draws electrons from K. Follow the same reasoning as chloroform.\n\nFor BaSO4, it is insoluble in water. Only barium nitrate dissolves in water. Other barium salts do not.\n\nHope this helps! =)

p-aminohippuric acid is also known as N-(4-Aminobenzoyl)glycine, N-(p-aminobenzoyl)aminoacetic acid, and PAH (not to be confused with PolyAromatic Hydrocarbons!)\n\np-aminohippruate is simply p-aminohippuric acid without the hydrogen on the -COOH group.  So the names above would still apply.

It's just another name for alkene.  Olefine is from Latin which means "oil forming gas" describes alkene well.  The link below have more information on alkene.

Amphipathicity is the nominal characteristic of amphiphilic substances. The most obvious biological advantage is that amphipathetic lipds form the two-layer eukaryotic cell membrane. From a commercially advantaged standpoint, amphipathetics are sold as surfactants.\n\n\nhttp://en.wikipedia.org/wiki/Amphiphilic

The stock name for this compound is ammonium phosphate.  \nThis is an ionic compound, which means that it is named with the names of the ions.  The cation (the first ion, positively charged) is NH4+, which is called ammonium.  The anion (the second ion, negatively charged) is called phosphate, PO4(3-).  \nNote that because the entire compound must be neutral, there are three ammonium (+) ions to balance out one 3- PO4 ion.

Okay, after a little bit of looking around I found this out:\n\nCalphalon also has PFCs so I wouldn't buy those.

It's a carbon-hydrogen chain. \nIt is used in organic reactions.

That is an IUPAC name, although it is an unspecified stereochemistry (the 2 and 3 positions can each be either R or S).\n\nThe trivial name for hexanoic acid is caproic acid.

fluon is a trade name for polytetrafluoroethylene (PTFE) which is also commonly known as teflon.  here is a page with a lot of material properties:\n\nhttp://www.agc.co.jp/english/chemicals/jushi/ptfe/PTFE.htm\nhttp://www.agc.co.jp/english/chemicals/jushi/ptfe/PTFE3.htm\n\ncheers!

Some are formulated to melt at lower temps some as low as 95 deg F. Some for use making candles and for food use melt between 170 and 200 deg.F. Their is no such thing as liquid parafin in a bottle no mater what it is labled. The waxes with a lower melting point are just a little more refined or have highly refined additives such as fregrent oils or light hydrocarbons

I believe it was catalase.  It comes from the term to catalyse which means to speed up or destroy.  Calalyses are not used up in chemical reactions just like enzymes.

Proteins are both amphoteric and zwiterrionic and so yes the term would be correct. When a protien dissolves in acid any free amine nitrogens will protonate and in base the amide links will deprotonate therefor amphoteric. In pure deionised water (pH-7) the acidic amide links will protonate the basic free NR3 and so also zwitterionic.

True any chemical produced or sold in huge quantities such as several liters are called bulk chemicals. It has nothing to do with the type of chemical but in the quantity that is ordered or bought.
