Is an R-NH-NH-R group classified as an amine, an azo, or neither?
113406
It's not an azo, because the nitrogen bond is not a double bond. It's not an amine because it has a nitrogrn-nitrogen bond.\n\nIt's a substituted version of hydrazine (H2NNH2), the famous rocket fuel.

what the others have answered are the elements consisting of ammonium sulphate and they've still got that wrong... it's nitrogen, hydrogen, sulphur and oxygen (no carbon and ammonia is NH3).\n\nChemical properties on following website: http://en.wikipedia.org/wiki/Ammonium_sulphate

All other common amino acids have a primary amino group. The primary amino group is essential for the formation of the purple chromophore.\nProline has a secondary amino group so the reaction is different\n\nHave a look at the link below

Just an initial note: NH3 is ammonia\n\nA. \nInitial math:\nSince you have 8.5 grams of NH3, you have to convert grams mols, then into molecules. \nSo you do: 8.5 grams of NH3 / 17 grams in 1 mole of NH3 and X 6.022 x 10^23 molecules in one mole\nYou get 3.011 x 10 23 molecules, and from that you subtract 1.5 x 10^23 molecules, and you get: \n<b>1.511 x 10^23</b>\n\nB. Then, you convert 1.5 x 10^23 to moles by dividing by 6.022 x 10^23 moles, which equals .249 moles of NH3. \nThen you convert 8.5 grams of NH3 to moles too by dividing 17 grams of NH3 per mole again, and get: .5 moles! \nso: .5 mol - .249 mol = <b>.241 mol</b>\n\nC. \nFrom before, you know 1.5 x 10^23 molecules of NH3 is .249 moles. You convert this to grams by multiplying .249 by 17 grams per mol and get: 4.233 grams. \nSo: 8.5 grams - 4.233 grams = <b>4.267 grams</b>\n\nD. From before, you know you have .241 moles of ammonia left. So, you multiply this by avocado's number (6.022 x 10^23) and get: 1.45 x 10^23 molecules of ammonia. Then, you can see that there are 3 atoms of hydrogen of per molecule of ammonia, and multiply the number of molecules by 3 and get: \n<b> 4.354 x 10^23</b> \n\nI think those should be right. Sorry about the sig figs though!

Ammonium (NH4+) is a polyatomic ion.  That means that it is composed of a group of atoms that are covalently bound together.  As a whole, that group has a charge of +1.  \n\nBecause this group of atoms has a charge, it is an ion, and can form ionic bonds with other ions.  So in summary, ammonium itself is a covalent compound, but it is able to form ionic bonds with other substances.

Actually under physiological conditions, this group is found as NH3+.

they have the formula R2SiO\nwhere R is methy of ethyl group

Trimethylamine, because there are three methyl groups attached to the nitrogen.  (I'm not sure why nitrogen compunds are called amines.)

Flaw in problem statement: hydrogen azide is HN3 -- NH3 is ammonia.  As usual, you will need the molar concentrations.  if the salts fully dissociate, the hydrogen from the HN3 will be added to the hydrogen in the water, and you can add these up to get the total hydrogen present.  From that, you can get the pH.

Primary and secondary amines would rival the alcohol for the bond with the carboxylic group, forming amides (also known as peptide bond). Tertiary amines cannot offer hydrogen for the elimination of water, and won't form quarternary aminium ions under esterification conditions.

An amide is the product of the reaqction between a carboxylic acid and ammonia, by the mechanism:\n\nR-C(O)-OH  + NH3 ===> R-C(O)O-NH4 (an ammonium salt)\n\nR-C(O)-ONH4 + HEAT ===> R-C(O)-NH2 (an amide) + H20\n\nA second mechanism is the reaction of ammonia with an acid chloride:\n\nR-C(O)OH  + SOCl2  =======>  R-C(O)-Cl\n\nR-C(O)-Cl + NH3 ==========> R-C(O)-NH2

HNO3\n\nIf you couldn't answer this question, you must be a real noob in chemistry!!  Well, for other times, here's the way to differentiate betwee acids and bases.\n\nAcids:   acids can be easily identified by the hydrogens they contain.  Most acids have their hydrogen in the beginning of their formula.  HNO3 can be easily identified as an acid: it is commonly called nitric acid.\n\nBases:  most bases can be identified by the (OH) group at the end of their formula... therefore, we can immediately label b) and d) as bases.   \n\nNow here, NH3 is kind of tough to define with the definitions given above.   I believe that the proper explanation is out of your scope for know (from what I can deduce).   So, you'll learn that later on.  But for your info, NH3 is ammonia, the stuff they use in cleaning fluids, and it is basic.\n\nHope this helps.

Ammonia is shipped as a liquified gas under its own vapor pressure of 114 psig. The oldest commercial refrigerant known and still in use today. Most extensive use is in soil fertilization. This application is used in the form of salts, nitrates and urea.\n\nIt is the simplest stable compound of these elements and serves as a starting material for the production of many commercially important nitrogen compounds. Pure ammonia was first pre-pared by Joseph Priestley in 1774, and its exact composition was determined by Claude-Louis Berthollet in 1785.

I hate it too. By the way it's NH3 - Ammonia that is formed. I got little time left. I'll answer later.

Na = Sodium\nO = Oxygen\nH = Hydrogen\n\nThe -OH group in this case is a hydroxide.  Therefore, NaOH is Sodium Hydroxide.  The (aq) stands for "aqueous".  When something is "aqueous" it is in water or it has water molecules attached.  Anhydrous means without water.  To explain this, let's look at ammonia.\n\nNH3 is anhydrous ammonia.  This means that there are no water molecules associated with this ammonia molecule.  \n\nNH4-OH, on the other hand, is aqueous ammonia (ammonia (aq)).  This means there is a water molecule associated with the ammonia molecule.\n\nI hope this helps.\n\n--Jim
