Different parts of the ocean do have slightly different isotopic concentrations: δ 18 O values range from –11.35‰ in water off the coast of Greenland to +1.32‰ in the north Atlantic, and δ 2 H concentrations in deep ocean water range from roughly –1.7‰ near Antarctica to +2.2‰ in the Arctic. Variations are much larger in surface ...

Depending on the formula and the symmetry of the structure, there might be several isotopomers of one isotopologue. For example, ethanol has the molecular formula C 2 H 6 O. Mono-deuterated ethanol, C 2 H 5 DO or C 2 H 5 2 HO, is an isotopologue of it. The structural formulas CH 3 −CH 2 −O−D and CH 2 D−CH 2 −O−H are two isotopomers ...

The refractive index of liquid water (1.333 at 20 °C (68 °F)) is much higher than that of air (1.0), similar to those of alkanes and ethanol, but lower than those of glycerol (1.473), benzene (1.501), carbon disulfide (1.627), and common types of glass (1.4 to 1.6). The refraction index of ice (1.31) is lower than that of liquid water.
(2*12.000)+(4*1.008)= 28.032 Da where it will be clear that two different molecules are going through the mass spectrometer. Note that the masses used are neither the integer mass numbers nor the terrestrially averaged standard atomic weights as found in a periodic table.
Some water spirits in traditional African religion include: Mami Wata is a transcultural pantheon of water spirits and deities of the African diaspora. For the many names associated with Mami Wata spirits and goddess, see Names of Mami Wata. [1] Owu Mmiri of some riverine people of Nigeria are often described as mermaid-like spirit of water. [2]
i = 1 for sugar in water; i = 1.9 for sodium chloride in water, due to the near full dissociation of NaCl into Na + and Cl − (often simplified as 2) i = 2.3 for calcium chloride in water, due to nearly full dissociation of CaCl 2 into Ca 2+ and 2Cl − (often simplified as 3)
