Identify all forces, indicate whether they are intramolecular or intermolecular forces, and identify the most important type of intermolecular forces for Ar. Name two intermolecular forces and briefly describe each one. Include what types of atoms or molecules are affect...
Let's imagine that we have placed a chunk of carbon tetrabromide in a beaker containing carbon tetrachloride. The carbon tetrabromide molecules in the solid are held together by very weak London dispersion forces, as are the carbon tetrachloride molecules in the solvent. One might expect, then,...
每个学校都应该组织一个足球队。 2.电视剧《金婚》很不错，它准确表达了中国普通人在几十年的时代变迁中的生活和命运。 3.维生素C可以防止感冒。一个诺贝尔奖获得者说的。 4.请把这份文件复印一份。 5. a：论证就是给出理由 b：不，不是. a：是，就是. b：不是，根本不是 以上哪个是通...
In liquids, intermolecular forces are still too weak to hold the molecules in place. The molecules have enough energy to repeatedly make and break the intermolecular bonds, sliding past one another and taking the form of their container. For example, in water, the bipole molecules are made up ...
Why is it that smaller bubbles have more excess pressure? Why doesn't air cause any dispersion? Why are water tanks broader at the bottom than at the top? Why do substances expand when the temperature is increased? Why does air sink at the poles?
5e). However, in the hexagonal clusters of triangular cells in the centers of the dodecagonal supertiles some steric frustration is retained, because the long chains of the molecules forming the walls between two triangular cells cannot escape into a square cell, and thus have to be ...
Exopolymeric substances (EPS) are polyanionic large organic molecules mainly composed of polysaccharides, but they also include proteins, nucleic acids and lipids (Decho and Gutierrez, 2017). HA like EPS is a polyanionic organic matter mainly containing abundant carboxyl and hydroxyl functional groups. ...
(Supplementary Note1), consistent with the fact that Cav1 molecules disperse upon tension-mediated disassembly of caveolae14and of Cav1 structures in our PTRFKO + Cav1 cells (Figs.4and5). Thus, predicted protein-rich domains were curved. A key parameter in our model is the spontaneous ...
Why wouldn't you expect all the molecules in a gas to have the same speed? Why does the pressure of gas enclosed in a rigid container increase as the temperature increases? State five factors that affect the rate of diffusion in gases. Why does water vapor in the air condense when the ...
The term "fundamental force" refers to the forces behind the interactions between the building blocks of matter, and cannot be reduced any further to any smaller interaction. In terms of increasing strength, the four fundamental forces are: gravitation, weak, electro...
