A chemical change can also be called a chemical reaction
<span>c.Solids have a fixed shape, so they do not show random motion of particles.</span>
The crust because there are tectonic plates.
nucleus: controls cell
cell membrane: controls what goes in and out of a cell
cytoplasm: where chemical reactions take place
<span>The answer is 4. The molecules of each material entice each other over dispersion (London) intermolecular forces. Whether a substance is a solid, liquid, or gas hinge on the stability between the kinetic energies of the molecules and their intermolecular magnetisms. In fluorine, the electrons are firmly apprehended to the nuclei. The electrons have slight accidental to stroll to one side of the molecule, so the London dispersion powers are comparatively weak. As we go from fluorine to iodine, the electrons are far from the nuclei so the electron exhausts can more effortlessly misrepresent. The London dispersion forces developed to be increasingly stronger.</span>
