X2952) for magnesium hydroxide. As a laxative, magnesium hydroxide is dosed at 2–5 g, and works in a number of ways. These products are sold as antacids to neutralize stomach acid and relieve indigestion and heartburn. Question =  Is SCN- polar or  nonpolar ? It is added directly to human food, and is affirmed as generally recognized as safe by the FDA. Answer =  CF2Cl2  (Dichlorodifluoromethane)  is  Polar What is polar and non-polar? Question =  Is CF2Cl2 polar or  nonpolar ? CsOH - cesium hydroxide Mg(OH) 2 - magnesium hydroxide. Weak bases ones are the ones with limited solubility, such as ammonia, NH3, is weak. 600 m3 (158,503 US gallons) of seawater gives about one ton of Mg(OH)2. This was so successful (advertised in Australia and approved by the Royal College of Surgeons in 1838)[11] that he was appointed resident physician to Anglesey and two subsequent Lords Lieutenant, and knighted. Some sources claim that the hydroxide ions themselves do not play a significant role in the laxative effects of milk of magnesia, as basic solutions (i.e., solutions of hydroxide ions) are not strongly laxative, and non-basic Mg2+ solutions, like MgSO4, are equally strong laxatives, mole for mole. Because brucite is a swelling mineral, it causes a local volumetric expansion responsible for tensile stress in concrete. It is a white solid with low solubility in water (Ksp = 5.61×10−12). It is a white solid with low solubility in water (K sp = 5.61×10 −12). Although the name may at some point have been owned by GlaxoSmithKline, USPTO registrations show "Milk of Magnesia"[14] and "Phillips' Milk of Magnesia"[15] have both been assigned to Bayer since 1995. It was used in Steven Spielberg's first short movie called Amblin'. As a consequence, chlorite interlayers are cemented by brucite and cannot swell nor shrink. This reaction, one of the two main alkali–aggregate reaction (AAR) is also known as alkali–carbonate reaction. [5] Magnesium hydroxide is a common component of antacids, such as milk of magnesia, as well as laxatives. Magnesia is valuable because it is both a poor electrical conductor and an excellent thermal conductor.[6]. [22] Like aluminium hydroxide, solid magnesium hydroxide has smoke suppressing and flame retardant properties. In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. Ca(OH) 2 - calcium hydroxide Sr(OH) 2 - strontium hydroxide. Brucite may also crystallise in cement and concrete in contact with seawater. Question =  Is C4H10 polar or  nonpolar   ? Not only does this increase in water content soften the feces, it also increases the volume of feces in the intestine (intraluminal volume) which naturally stimulates intestinal motility. Some magnesium hydroxide products sold for antacid use (such as Maalox) are formulated to minimize unwanted laxative effects through the inclusion of aluminum hydroxide, which inhibits the contractions of smooth muscle cells in the gastrointestinal tract,[18] thereby counterbalancing the contractions induced by the osmotic effects of the magnesium hydroxide. His fluid magnesia product was patented two years after his death in 1873.[12]. [19] Magnesium hydroxide is useful against canker sores (aphthous ulcer) when used topically.[20]. Since the dissociation of this small amount of dissolved magnesium hydroxide is complete, magnesium hydroxide is considered a strong electrolyte. Again, like the strong acids, the strong bases are completely ionized in water solution. However, magnesium is mainly excreted by the kidneys so long-term, daily consumption of milk of magnesia by someone suffering from kidney failure could lead in theory to hypermagnesemia. It occurs in nature as the mineral brucite. Magnesium hydroxide is used in suspension as either an antacid or a laxative, depending on concentration. [13] It was sold under the brand name Phillips' Milk of Magnesia for medicinal usage. Answer =  C2Cl4 (  Tetrachloroethylene )   is nonPolar What is polar and non-polar? Answer =  TeCl4 (  Tellurium tetrachloride )   is Polar What is polar and non-polar? Question =  Is C2Cl4 polar or  nonpolar   ? Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).
