Why is water an important molecule? Water: We have different compounds and substances in chemistry and some may look the same but some properties and reactivities will be different. Out of the million compounds we may encounter, we all know water as an example of a compound. We have many ...
Chapter 2 Why is water such an important molecule to all living things ?Alone, Are We
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] ...
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 ...
题目 Water is actually quite simple, but the way how the water molecule is formed gives water its unique properties. 相关知识点: 试题来源: 解析答案:解析: the way 已经表示方法,how怎样,同样表示方法 提示: 去掉how或how→that/in which
Answer to: Explain why water is a polar molecule. What do the polarity and shape of water molecules have to do with their ability to form hydrogen...
Oygen is more electronegative (EN = 3.5) than hydrogen (EN 2.1) hence, O- H bond is polar. In the water molecule, two polar O-H bonds are present which are held together at an angle of 104.5^(@). Due to the resultant of these two dipoles, water molecul
a== H2O == Water is H2O, 2 molecules of hydrogen and 1 molecule of oxygen. Water is slightly polar (has an electric charge). Surface tension and capillary action are the properties that result from polar water molecules. Surface tension is the property of water molecules clinging to each ...
The humble water molecule is made up of two hydrogen atoms bonded to an oxygen atom. "The way they're bonded together makes water this wonderful universal solvent," meaning that almost every substance can dissolve in water, Glazer told Live Science. That's because the molecule has polarity, ...
A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water ...
