This compound is also used to control hyperphosphatemia (elevated phosphate, or phosphorus, levels in the blood) in people and animals suffering from kidney failure. Normally, the kidneys filter excess phosphate out from the blood, but kidney failure can cause phosphate to accumulate. The aluminium...
A molecular formula describes which atoms are present in a molecule. The subscript number found after the elemental symbol indicates the number of atoms present for each element in the molecule. Answer and Explanation: The molecular formula of ammonium nitrate is NH4NO3. The molecular formula indicat...
odor and a mild taste. Insoluble in cold water, can be dispersed in hot water to form a milky solution. It can be dissolved in hot oil and various organic solvents to form a milky solution. The freezing point is 45~47℃, and the HLB value is 6.7. Sorbitan monopalmitate is used in...
Sodium chloride is an ionic compound, but what is an ionic compound? Ionic compounds are a type of chemical compound where the oppositely-charged ions of a metal and a nonmetal are attracted to each other to form an ionic bond. The compound formed from the bonded ions will have very ...
Boron nitride is prepared by heating boric oxide with ammonia: B2O3 + 2NH3 → 2BN + 3H2O Alternatively, the compound can be prepared by heating boric oxide or boric acid with ammonium chloride or an alkali metal cyanide. Purified product can be obtained by high temperature reaction of boron...
electrically nonconductive. Several of these are white and can be used with a range of colorants. for example, is called “white graphite” because it has a hexagonal, platy structure like graphite. The filler is also nonabrasive and has a low density.2Aluminum oxide and nitride are more ...
