The names of some organic molecules incorporate specific information about stereochemistry using shorthand notation. One such example is (2R,3R)-2-bromo-3-chlorobutane. This name is written following the nomenclature rules established by IUPAC (International Union of Pure and Applied Chemistry). These rules specify the punctuation to be used in writing the name of a molecule. Write this name exactly as it appears above. (Note: You will not be able to italicize the "R" labels, but you should match exactly the punctuation in the rest of the name.)

Read these sentences from the text. near the equator, the tropics receive the most rain on a consistent basis. as a result, the fresh water falling into the ocean decrease the salinity of the surface water in that region. [. .] . . as the salt content of sea water increases, so does its density. what can you infer about how rain affects the density of surface water near the equator?

Ase your answer to this question on the information below. hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant. the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen. chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product. nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

In which phase(s) do the molecules take the shape of the container?
