【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...
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 ...
An atom is the indestructive fundamental unit of matter. A molecule is a substance that is made up of two or more atoms. The atoms constructing a molecule can either be of the same element or of different elements.Answer and Explanation: A molecule or ...
What is an atom in a molecule? J Phys Chem A The derivation of the Hirshfeld atoms in molecules from information theory is clarified. The importance for chemistry of the concept of atoms in molecules (AIM) is stressed, and it is argued that this concept, while highly useful, consti... ...

Our simulations used a solvent molecule to coordinate the bound metal, but it is possible that the conserved aromatic residue at position 893 indirectly participates in coordination of the metal (13). For example, the π-ring system of Tyr-893 could coordinate a solvent molecule that participates...
I know that the answer depends on whether your reference uses 1.7 or 2 as an electronegativity difference, but I'm still a little confused beyond that. If the iron atom in Fe2O3has a +3 charge, which means it's an ion. So therefore you'd think the molecule is ionic. But apparently...
