At higher temper- atures, the molecules have more energy and it is easier for them to overcome the forces holding them within the liquid and to vaporize; so there are more molecules in the vapor state.The vapor pressure decreases with addition of solutes, such as salt or sugars. In effect...
Which of the following bonds has the highest bond energy ? View Solution Nitrogen , oxygen and fluorine are the highly electronegative elements. When they are tied to a hydrogen atom to form covalent bond, the electrons of the covalent bond are shifted towards the more electronegative atom.This...
Based on the cured structures elucidated from the FT-IR result, the numbers of multiple hydrogen bonds and cross-linking covalent bonds (NMHB and NCB), and total cross-linking bond energy (ETB) were evaluated to be 0, 7.92, and 618 for BMI-DAIC-ML411, 0.71, 7.81, and 627 for BMI-...

Hydrogen bonds involve the sharing of a hydrogen atom between two electronegative atoms that have unbonded electrons. These bonds, although weak compared to the bonds discussed above, are important in water-water interactions and their existence explains many of the unusual properties of water and ice...
How about in biology? What does covalent bond mean?In biology, the covalent bond is one of the three major types of chemical bonds that are biologically important; the other two areionic bondsandhydrogen bonds. The covalent bond, though, is distinct from these two bonds in such a way that...
Which type of bond must be broken for water to vaporize? a) Ionic bonds b) Polar covalent bonds c) hydrogen bonds d) both polar covalent bonds and hydrogen bonds. What is required for a hydrogen atom to be able to bond? In a covalent bond, a pair ...
The hydrogen and chlorine atoms each donate one electron to the covalent bond. In the molecule, the hydrogen has completed its valence shell with two electrons, and the chlorine has a full shell with eight valence electrons. In some molecules, bonded atoms share more than two electrons, as in...
2-7 Covalent Bonds Anatomy来自希腊语anatome,“解剖”,是处理生物结构组织的自然科学的一个分支。作为基础生命科学之一,解剖学与医学和其他生物学分支密切相关。(网易公开课编辑整理)
Covalent Bonds between Different Atoms Now that we have looked at electron sharing between atoms of the same element, let us look at covalent bond formation between atoms of different elements. Consider a molecule composed of one hydrogen atom and one fluorine atom: ...
