WebAnswer (1 of 2): There are hundreds, of course, but we can start easy. The simplest distinction is between ionic and covalent compounds, like salt and gasoline. Ionic solids (and they are almost all solids at room temperature) are held together by the direct attraction of positive and negative i... WebApr 7, 2024 · Supercritical CO2 (scCO2) extrusion foamed high-melt-strength (HMS) polypropylene (PP) often suffers from low cell density, large cell sizes, and poor cell structure uniformity due to the poor nucleation rates of CO2 in the PP. To remedy this, various inorganic fillers have been used as heterogeneous nucleation agents. Although …

Webb. At 25 o C, chlorine (Cl 2) is a gas whereas bromine (Br 2) is a liquid. Why? London dispersion forces are responsible for the formation of the solids. As the elements are cooled, the kinetic energy of the Cl 2 and Br 2 molecules decreases and the London forces are strong enough to overcome the kinetic energy and hold the molecules in a solid. Web14. Dispersion force is the only force present in nonpolar molecules. Answer: Dispersion forces are present between all molecules, whether they are polar or nonpolar. Larger … 1w能配什么电脑
