Which of these properties describes a metal? a. brittle b. conducts heat very well c. fragile d. transparent Elements: Element is a substance that can exist as a single identifiable unit and can be broken down into simpler substances. The periodic table list...
This invention relates to a process for the preparation of chemical compounds. The continuous manufacture of chemical compounds has been known for a number of years. For example, U.S. Pat. No. 4,252,718 describes a continuous process for the preparation of an aqueous slurry of water-insoluble...
Which of the following processes are exothermic? a. NaF(s){eq}\rightarrow {/eq}Na(g)+F(g) b. Cl2(g){eq}\rightarrow {/eq}2Cl(g) c. Br(g)+e{eq}\rightarrow {/eq}Br(g) d. Li(s){eq}\rightarrow {/eq}Li(g...
Changes in flagellar steady-state stiffness upon octopamine injections were calculated from force-step actuation8as an indication of the ear’s baseline properties and their relative contribution to flagellar sensitivity (Fig.2c). The flagellar steady-state stiffness describes the force required to hold...
This example describes the analysis of samples of lysed whole blood, plasma, and erythrocytes for free choline. Ten random samples of whole blood were collected in ethylene diamine tetra-acetic acid (EDTA), kept on ice, and analyzed within three hours of drawing. Microhematocrits were measured ...
In the titleDon’t Tell Mom the Babysitter’s Dead, “Tell,”“Mom,”“Babysitter,” and “Dead” are all major words—they’re verbs (tell), nouns (mom,babysitter), and adjectives (deaddescribes the babysitter), and they all very much impact the sentence’s meaning. Because of that,...
truth is, we are all-naturally full of several types of steroids. The phrase “steroid” only describes a compound having a “spine” of four bands of carbon — for example estrogen, progesterone, hydrocortisone, as well as cholesterin. Whereas testosterone was proved to be comparatively safe,...
5,236,987 describes the use of benzoates derived from C8-C12 alcohols in plastisols. The use of these compounds by way of example in latex formulations is also described. DE 19 62 500 discloses compositions which comprise a vinyl polymer and one or more esters of benzoic acid with a ...
This invention concerns a method of purifying phenothiazine. Phenothiazine is a well-known compound which is used as an insecticide and as an anthelmintic for the internal treatment of animals. The literature describes it as a crystalline yellow compound which melts at 180* C. and turns green.....
EXAMPLE:A compound of formula II. USE:The derivative of formula I is a component for colored liquid crystal compositions useful for liquid crystal displays. The derivative of formula I is a liquid-crystallizable compound having a color, thereby providing liquid crystal elements having substantially ...
