【答案】consistsof【核心词汇】molecule 分子;atom 原子【翻译】一个水分子由两个氢原子和一个氧原子组成。【解析】本题考查同义词组转换。根据句意,一个水分子由两个氢原子和一个氧原子组成。makeupof 由...组成,consistof 由...组成,因为主语是A moleculeofwater 一个水分子,所以谓语动词要用第三人称单数形...
In this research, we are interested in the non-bonded interactions between a single water molecule and the atoms Li, Na, K, Rb, Cs, Ca, Ni, Zn and Pb inside a C 60 fullerene using the Lennard-Jones potential function. We assume that a single water molecule is inside the endofullerene...
根据句意“一个水分子是由两个氢原子和一个氧原子组成的”,“由...组成”可译为bemadeupof,也可译为consistof,consistof 不用于被动语态,根据原句中的is可知应用一般现在时态,主语A moleculeofwater是单数形式,故谓语动词应用第三人称单数形式,故填consistsof。 反馈 ...
In case the number of polyatomic ion is one, the bracket is not required. Molecular Mass The molecular mass of a substance is the sum of the atomic masses of all the atoms in a molecule of the substance. This is also expressed in terms of uFormula Unit Mass...
Calculated interaction energies have suggested that the shift in the water bending frequency is related to the degree of bonding between the metal atom and water molecule. A shift in the water bending frequency was not observed for Ni and Cu, and only a comparatively small shift in the case ...
.In a condensation reaction, two molecules combine and a molecule of ___is produced.4.A substance that tends not to react with water, "Water hating" , is___5.Breaking of ___ bonds is the first thing that happens when water isheated, whichmeansthat it takes a great deal of thermal...
Logically, when two atoms chemically bond to form a molecule, their electrons, which form the outermost region of each atom, come together first as the atoms form a chemical bond.Watch this video for a more in-depth introduction to the periodic table:...
(1) In high-pressure systems, the molecule s inside the system move faster than those th at surround it. T he opposite occurs in low-pre ssure systems, where the air inside the low is moving more slowly than in the surrounding area.Air flows around a high-or low-pressure sys tem in...
5f, when two neighboring Cu atoms act as adsorption sites of H− and OH−, respectively, the activation energy of n-Cu/BP for the dissociation of the water molecule is 0.63 eV, lower than that of the isolated Cu/BP (1.82 eV). This indicates that O–H bond is prone to ...
5a), indicating stronger hydrogen binding abilities after Co atom substitution, which should lead to the obstacle of thermodynamic H* desorption process in the Heyrovsky step. Actually, relatively inert H2O molecules are the reacting species for HER in alkaline media, and hence the water ...
