The primary hazard of working with 2,4,6-trinitrobenzenesulfonic acid is the risk of instantaneous explosion. 2,4,6-Trinitrobenzenesulfonic acid is an extremely sensitive compound especially when mixed with other compounds, exposed to heat, or exposed to rapid temperature or pressure changes.
This problem has a graph-theoretic solution in which a graph with four vertices labeled B, G, R, W (for blue, green, red, and white) can be used to represent each cube; there is an edge between two vertices if the two colors are on the opposite sides of the cube, and a loop at a vertex if the opposite sides have the same color. Each individual ...
Sodium bis(2-methoxyethoxy)aluminium hydride (SMEAH; [1] trade names Red-Al, Synhydrid, Vitride) is a hydride reductant with the formula NaAlH 2 (OCH 2 CH 2 OCH 3) 2. The trade name Red-Al refers to its being a reducing aluminium compound. It is used predominantly as a reducing agent in organic synthesis. The compound features a tetrahedral ...
1,2,4,5-tetrachlorobenzene once was used as intermediates in the production of pesicides, [3] specifically trichlorophenols. This method has been discontinued because it also produced 2,3,7,8-tetrachlorodibenzo-p- dioxin .
A version lets the solver shoot at 3 positions in one turn. The answer is returned sorted by size. For instance: (1,2) - (3,6) - 6,4) => 420 means that one of the three coordinates hit is a ship size 4, another a ship size 2. One coordinate returned a miss.
Normal serum osmolality ranges from 280 to 290 mOsm/kg and serum osmolality to cause water removal from brain without much side effects ranges from 300 to 320 mOsm/kg. Usually, 90 mL of space is created in the intracranial vault by 1.6% reduction in brain water content. [1] Osmotherapy has cerebral dehydrating effects. [2]
Reductive elimination is sensitive to a variety of factors including: (1) metal identity and electron density, (2) sterics, (3) participating ligands, (4) coordination number, (5) geometry, and (6) photolysis/oxidation. Additionally, because reductive elimination and oxidative addition are reverse reactions, any sterics or electronics that ...
The basis for the recent history for memory erasure has been focused on determining how the brain actively keeps memories stored and retrieves them. There have been several instances where researchers found drugs that when applied to certain areas of the brain, usually the amygdala , have relative success in being able to erase some memories.
