The capillary constants have been determined by the hanging-drop method for liquid vanadium, niobium, and tantalum, while the density has been determined from the indirect determination of the volume of the detached part of a hanging drop, from which the specific surface free energy has been calc...
Why does phenol have a higher boiling point than chlorobenzene, even though chlorobenzene has a higher molecular weight than phenol? Which has a higher boiling point: CH4 or CCl4? Explain. Rank the following ionic compounds from lowest to highest melting point. a. CaF2 b. RbF c. KF...
of ionic liquids are molten salts at room temperature, some ionic liquids have a melting point as high as the boiling point of water. TheTmof an ionic liquid depends on the strength of the crystal lattice which, in turn, is decided by the strength of the intermolecular forces between ions...
