How does an atomic absorption spectrophotometer work? Describe how you could separate the following mixture of metal ions: Cd2+, Pb2+, and Sr2+. Describe how you could separate the following mixture of metal ions: Na+, Hg2+, and Ca2+. Explain why t...
The increasing and substantially greater range in 87Sr/86Sr and 143Nd/144Nd for the continental, compared with oceanic, volcanic rocks primarily reflects increasing amounts of assimilation during fractional crystallization of continental lithosphere by some magmas. Radiogenic ingrowth in some of the ...
The static stress mechanism does fit within our classification, but it did not trigger the eruption per se. An elegant solution proposed by Marzocchi57 is to use the term “promote” rather than “trigger” in order to emphasize the complex nature of these processes. Changes in unrest vs. ...
Intermediate rotations of single peptides are identifiable from large displacements of the carbonyl O density: many can be fit well with the Backrub tool (e.g., 1PQ7 Ser132 and 1US0 Arg40) although the sidechain does not always move (e.g., 1N9B Ser41, which preserves two helix N-...
How does gas chromatography work? When performing the liquids and solids experiment, when is the Acetamide in a condensed phase? Explain your answer. What are the two properties of substances that enable them to be separated by chromatography? How can you separate Ag+, Bi3+, and Ni2+ ...
Answer to: Describe the process of recrystallization as a method for purification of a solid. How does it work? What do you do? By signing up,...
