【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 ...
One electromagnetic resonance device is molecule, atom, provides the chemical modification of water. Device includes a water tank, a resonance induced cell tower, an electronic control unit, one 12 volts of power sources, the DC of ac power inverter, for storing a pressure vessel of the ...
Water is a polar molecule because the electronegativity of oxygen is higher than that of hydrogen, meaning that the electron density is shifted towards the oxygen atom in the molecule. Water is a polar molecule because its oxygen is strongly electronegative and, as such, pulls the electron pair...
A water molecule (分子) is made up of 2 hydrogen atoms and l oxygen atom. It can be changed only by aspecial way of controlling of the atoms. The material made into the cup can have nanometer particles. But it cannot change the chemical and physical properties of the water contained in...
of an atom,while we learnt in P08 Curious glow that the electrons are found in different energy levels about an atom.Determine whether a water molecule is overall positively charged,neutral or negatively charged by considering the total number of protons and electrons found in a water molecule. ...
aWater is a very simple molecule (two hydrogen atoms combined with one oxygen atom), but that simple combination allows the emergence of exceptional properties that have made water the most important solvent on earth and an essential support to the development of life. [translate] ...
Dioxygen molecule has 2 oxygen atoms bonded together. Water molecule has 2 hydrogen atoms and 1 oxygen atom bonded together. Carbon Dioxide molecule has has 1 carbon atom and 2 oxygen atoms bonded together. Submit Your Comment: Please write meaningful comments. Thanks! ☺ Your Name: Let ...
Since oxygen has a higher electronegativity than hydrogen, the side of the molecule with the oxygen atom has a partial negative charge. A molecule with such a charge difference is called a dipole. The charge differences cause water molecules to be attracted to each other (the relatively positive...
