英语翻译We assumed that there were forces of attraction between molecules which varied rapidly with the distances so that the attraction between molecules that were more than a few ten millionths apart was very small but became considerable when the molecules approaches more closely. 答案 我们假定有...
4 (a) State the evidence for the assumption that(i) there are significant forces of attraction between molecules in the solid state,[1](ii) the forces of attraction between molecules in a gas are negligible.[1](b)Explain, on the basis of the kinetic model of gases, the pressure exerted...
van der Waals forces 例句 1.The molecules are held together by Van der Waals forces. 分子是由范德华力约束在一起的. 2.Physical adsorption depends on van der Waals forces of attraction between molecules and condensation of liquids. 物理吸附取决于固体吸附剂和被吸附物的分子间的范德瓦耳斯力. ...
Intermolecular Forces Section 5 Molecular Geometry Chapter 6 Intermolecular Forces The forces of attraction between molecules are known as intermolecular forces. The boiling point of a liquid is a good measure of the intermolecular forces between its molecules: the higher the boiling point, the stronger...
The forces of attraction between molecules of I_2 are: (a) covalent bonds. (b) ionic bonds. (c) dipole-dipole attractions. (d) London forces hydrogen bonds. The dominant intermolecular attractive force between NH3 molecules is: a. dipole forces...
n. (1) Weak forces between atoms or molecules due to momentary fluctuations in their electronic charge-cloud distributions. (2) The force of attraction between molecules possessing no permanent dipole. The interaction energy is given byn.where h is the Planck's constant, V o the characteristic ...
Specific InteractionsIntermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms, molecules or ions). They are weak compared to the intramolecular forces, which keep a molecule together (e.g., covalent and ionic bonding). Van der Waals ForcesVan der Wa...
Hydrogen bond Special dipolar attraction Attraction occurs between molecules containing H bonded to a small, electronegative atom (N, O or F only) with at least one lone pair of electrons
attractions are attractions between one molecule and a neighbouring molecule. The forces of attraction which hold an individual molecule together (for example, the covalent bonds) are known as intramolecular attractions. These two words are so confusingly similar that it is safer to abandon one of ...
What kind of intermolecular forces act between a sodium cation and a hydrogen sulfide molecule?Intermolecular forces:Intermolecular forces of attraction are those forces of attraction that exists between molecules. These forces affect the physical properties of molecules. ...
