In plumbing, a trap is a U-shaped portion of pipe designed to trap liquid or gas to prevent unwanted flow; most notably sewer gases from entering buildings while allowing waste materials to pass through. In oil refineries, traps are used to prevent hydrocarbons and other dangerous gases and chemical fumes from escaping through drains.
In chemistry, a chemical trap is a chemical compound that is used to detect unstable compounds. [1] The method relies on efficiency of bimolecular reactions with reagents to produce a more easily characterize trapped product. In some cases, the trapping agent is used in large excess.
The sharp series limit is the same as the diffuse series limit. In the late 1800s these two were termed supplementary series. In 1896 Arthur Schuster stated his law: "If we subtract the frequency of the fundamental vibration from the convergence frequency of the principal series, we obtain the convergence frequency of the supplementary series".

P 4 Se 3 and P 4 S 3 adopt the same structures. [1] These compounds can be melted together and form mixed crystals of one dissolved in the other. [4] Under higher temperatures, mixed chalcogenide molecules P 4 S 2 Se and P 4 SSe 2 will form. [5] P 4 S 3 is produced by the reaction of red or white phosphorus with sulfur. Excess sulfur gives ...
The partition coefficient, abbreviated P, is defined as a particular ratio of the concentrations of a solute between the two solvents (a biphase of liquid phases), specifically for un-ionized solutes, and the logarithm of the ratio is thus log P.
Elizabeth's PTSD is much more prominent on the show than it is in the books. In both the book and the show, Elizabeth is raped by a professor at UCLA, which leads to her quiet dismissal from the ...
Analytical chemistry – Study of the separation, identification, and quantification of matter; Chemical process – A method or means of somehow changing one or more chemicals or chemical compounds. High-performance liquid chromatography – Technique in analytical chemistry; Unit operation – Basic step in a process
Here are all the notable differences between the Love in Chemistry book and TV show. 1. In the book: Elizabeth Zott is a chemist at the Hastings Research Institute, with her own lab technicians ...
