Why Is Water Polar? 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, pu...
14. Because water is polar,it can___or dissolve both solids and gases. 因为水是带正电的,所以它能分解固体和气体。(p.19 Chemical Structure 第6行) ▲break down是个常用词组,我们在高二上册同步讲解中已作过解释,但此处break down作“分解”解。如: 1 Chemicals in the body break our food down ...

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...

It is particularly useful for studying a polar environment like water and water-solvated samples. In biological samples, the dielectric relaxation of water is called γ-dispersion, and falls in the microwave range (between 0.5 and 50 GHz)11,12,13 (Fig. 1). Figure 1 Schematic presentation ...
