As an extension of this reactivity, PhB(OH) 2 can be used as a protecting group for diols and diamines. This reactivity is the basis of the use of phenylboronic acid's use as a receptor and sensor for carbohydrates, antimicrobial agents, and enzyme inhibitors , neutron capture therapy for cancer , transmembrane transport , and bioconjugation ...
M L T −1: Angular momentum about a position point r 0, L, J, S = Most of the time we can set r 0 = 0 if particles are orbiting about axes intersecting at a common point. kg m 2 s −1: M L 2 T −1: Moment of a force about a position point r 0, Torque. τ, M
2,4-Dichlorophenoxyacetic acid is an organic compound with the chemical formula Cl 2 C 6 H 3 OCH 2 CO 2 H.It is usually referred to by its ISO common name 2,4-D. [4] It is a systemic herbicide that kills most broadleaf weeds by causing uncontrolled growth, but most grasses such as cereals, lawn turf, and grassland are relatively unaffected.

The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane. [2] It is called the shoelace formula because of the constant cross-multiplying for the coordinates making up the ...
For instance 1 ⁄ 5 can be generated with three folds; first halve a side, then use Haga's theorem twice to produce first 2 ⁄ 3 and then 1 ⁄ 5. The accompanying diagram shows Haga's first theorem: = +. The function changing the length AP to QC is self inverse.

It exists as the anhydrous salt Ce(SO 4) 2 as well as a few hydrated forms: Ce(SO 4) 2 (H 2 O) x, with x equal to 4, 8, or 12. These salts are yellow to yellow/orange solids that are moderately soluble in water and dilute acids. Its neutral solutions slowly decompose, depositing the light yellow oxide CeO 2. Solutions of ceric sulfate have a ...
