(ii) State the property of water that enables these bonds to form. [1] 相关知识点: 试题来源: 解析 (i) 氢键 (ii) 水分子的极性 (i) 水分子之间形成的键叫做 氢键。 (ii) 水分子能够形成氢键的原因是其 极性。水分子中的氧原子带部分负电荷,氢原子带部分正电荷,这种电荷分布使得水分子之间能够...
Hydrogen bond between water molecules (dashed lines). Double points near O mean lone pairs of electrons, solid lines—covalent bonds. Because of the relative weakness of the hydrogen bonds, they appear in a dynamic equilibrium. For example, in water they are destroyed and reappear, and their ...

Monosaccharides are covalently linked to each other or to other molecules through glycosidic bonds. These linkages are among the most stable in nature, but glycosyl hydrolases (GHs) accelerate their breakdown by a factor of 1017 compared to the rate of spontaneous autohydrolysis. That is the reason...

5、Regarding harmonic oscillator as a model ofchemical bond, the energy transfer processes between water molecules can be described as a system of harmonic oscillators.(用谐振子作为化学键的模型,水分子之间的能量转移过程可以描述为耦合谐振子系统。) ...
complex is 3.65Å. CH001.qxd 11/8/2006 3:26 PM Page 5 Hydrogen bonds Between these two electrical interactions—covalent between atoms and Van der Waals between molecules—exists an intermediate interaction, called the “hydrogen bond”, that ...
Water molecules bond with other water molecules by a weak ___ bond. Hydrogen Bond in Water: One of the most used solvents in the field of chemistry is water. It is considered an important molecule for living organisms since it is involved in most of the biological reactions in the...
One method for increasing capacity is to insert between the conductors an insulating material that reduces the voltage because of its effect on the electric field. Such materials are called dielectrics (substances with no free charges). When the molecules of a dielectric are placed in the ...
[52] Such studies also confirm the existence of hydrogen-bonded water molecules at metal/oxide water interface in almost an ice-like fashion [51–52] and that the polarity of the surface potential can control the orientation of the water molecules at the surface [52] It is also highly ...
