This is an attractive interaction between a hydrogen atom from a molecule or a molecular fragment X-H in which X is more electronegative than H, and an atom or a group of atoms in the same or a different molecule, in which...
Why is water considered a dipolar molecule? Why are hydrogen bonds important? Why are hydrogen bonds important for life? Why is drinking water important? Why is H bonding so important to water's properties? Why is water considered a polar molecule?
said Chris McKay, an astrobiologist at the NASA Ames Research Center in Moffett Field, California. Ammonia, like water, is a polar molecule that is relatively abundant in the universe, but scientists haven't found
Is HCl more soluble in water or kerosene? Explain. Is NaCl considered a molecule? Explain. Explain the important points regarding the molecule of 'Benzene'. Why are polar solvents best suited for the SN1 reaction? Explain polar, non-polar, and the difference between the two. ...
Why is PH3 a polar molecule when P and H have the same electronegativity? Is it because of the lone pair on P, making electron density greater on P? The dipole moment is 0.58 D. Is there slightly greater electron density towards the P or the Hs? Are the covalent bonds herein polar ...
Why is carbon is considered tetravalent? Why is carbon so versatile? Why are the molecules of hydrocarbons nonpolar? Why is the water molecule so important to organisms? Why is water an important molecule? Why are functional groups important in organic chemistry? Why is inorganic chemistry importan...
Therefore it is obvious that the spreading properties of foam forming liquid are of great importance for this application. To ensure the quick and complete spreading, the foaming liquid contains both hydrocarbon and fluorocarbon surfactants: the hydrocarbon surfactants decrease the hydrocarbon/water ...
Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Why all macromolecules are not polymer? A polymer always consists of thousands of repeating monomers units. However a macromolecule is a giant molecule which may or may not contain monomer units. Why are lipids ...
打个比方就好比每天晚上你的电脑或者手机要进入维护模式,进行磁盘碎片整理(memory 的转移和索引),安装固件更新漏洞补丁(增强免疫系统功能)之类的,喝醉昏睡过去大概就等价于强行拔掉电源——虽然两种情况电脑都黑屏了,但是第二天重启的时候立刻就会知道区别很大。而熬夜晚睡则相当于长期运行内存效率低下、没有补丁的“裸奔...
Water is considered a versatile solvent because it can dissolve different kinds of solutes than any other liquid. Water is a polar molecule and...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough ...
