WebJan 9, 2016 · For example, a higher boiling point in water isotopologues may be better explained by a reduced zero-point energy in the intermolecular hydrogen bonds. This seems to be supported by the fact that $\ce{D2 ^{16}O}$ and $\ce{H2 ^{18}O}$ have essentially the same mass, but their boiling points are 101.42 ºC and 100.15 ºC … WebApr 3, 2024 · A volumetric flask will commonly have the capacity in milliliters, the lettered class of the flask, one or more etched capacity rings, and the temperature at which the …

WebJan 30, 2024 · Explanation: Inspite of having similar intermolecular forces, CS2 has a higher boiling point than CO2, since it has a greater molar mass. The potential energy of molecules reduces until a certain level as they get closer to each other. Although the polarity of both CO2 and CS2 are cancelled because of their linear structure. Advertisement. WebMar 31, 2024 · The high boiling point of dimethyl sulfoxide (DMSO) makes it a preferred solvent in the preparation of Cs 2 PbI 2 Cl 2 /CsPbI 2.5 Br 0.5 inorganic perovskite. When the perovskite films are prepared by the one-step solution method, it is difficult to evaporate the residual solvent molecules from the prefabricated films, resulting in films with ...
