Both points expressed above are true. A molecule of Hg is indeed heavier that a molecule of air. \n\nBut to say that comparing density will tell how molecular weight compares will not always be true. Density is weight (or mass, it's expressed both ways) per volume so it could be that the density difference is because of how close together the molecules are. \n\nExample: Argon (atomic weight - almost 40) is a gas in normal conditions. It's less dense than water (molecular weight - about 18).

NaCl IS A MOLECULE CALLED TABLE SALT!\nNH3 is not a molecule because the nitrogen atom is not bonded to another atom/atoms using all of its valence electrons and is therefore not a molecule, it is an ion.

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

1.) do your own homework\n2.) this is the computer forum, not high-school chemistry.  Next time post to the right furom.

L-arginine is considered a semi-essential amino acid and is thought of as one of the bodybuilding amino acids because the body uses it to release growth hormone. Human growth hormone is used by the body to build muscle strength and tone and to enhance the burning of fats. L-arginine is important in the urea cycle for the metabolism of ammonia produced in the breakdown of protein. L-arginine also stimulates the production of nitric oxide which supports vasodilation.\n\nhttp://lookup.herballoveshop.com/search?q=l+arginine&site=my_collection&client=my_collection&proxystylesheet=my_collection&output=xml_no_dtd&filter=p&getfields=PID.price.ProductImage.Rating.description.mytitle.details

Chlorine ion has one more electron than cholorine atom.  It take on one more electron to have the same number of electrons as the nearest noble gas: argon.\n\nFluorine atoms gain one more electron to become an ion.  One more negative charge.  It takes on one more electron to have the same number as the nearest noble gas: neon.  Fourth answer only.

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

transamination is involved in the interconversion of certain amino acids. \nEg Aspartate Aminotransferase catalyzes the movement of an amine group from glutamine onto α-ketoglutarate.\npyrodoxal phospate is a co factor of many of these enzymes including Aspartate Aminotransferase.

ATP and ADP have the same ribose and adenine, they don't differ in that. the only difference between them is that ATP contains three phosphate groups while ADP contains two phosphate groups.\n\nATP: Adenosine triphosphate\nADP: Adenosine diphosphate\n\nribose is the sugar and adenine is the nitrogen base in both ATP and ADP
