Approximately how much greater in mass is a D2O molecule than an H2O molecule? (Assume the oxygen atoms have a mass number of 16. Deuterium, D, is an isotope of hydrogen with a mass number of 2, 2H.)
in amumass of D = 2
mass of O = 16
mass of D2O = 2*2 +16 = 20g/mole
mass of H2O = 1*2 + 16 = 18g/mole
mass of D2O is 2g/mole greater than mass of H2O
answer is 2 greater than H2O

(16) 6. Deuterium is the isotope of hydrogen of mass number 2, with a proton and a neutron in its nucleus. It is often designated 2H, or D. We have seen that the chemistry of deuterium is nearly identical to the chemistry of hydrogen, except that the C-D bond is slightly (1.2 kcal/mole) stronger than the C-H bond. a) Propose (show) a mechanism to explain each product in the following reaction: CH2-CHCH CH CH CH3 CH3 CH CH3 KOH +...

C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...
how would you synthesize the following Deuterium (D)) is an isotope of hydrogen (H). Both D and H have one proton and one electron; H has no neutrons and D has one. Consequently, D and H have nearly identical behavior. but they can be distinguished from each other experimentally due to their different masses. Therefore, replacing an H with a D in a molecule - deuterium isotope labeling-can provide valuable information about a mechanism. With this in mind, how would...
