Indicate whether each of the following statements is true or false. (3 pts) always use the exact calculated volume of solvent when purifying a solid by recrystallization. when recrystallizing a sample, you should always add as much solvent as needed to dissolve all of the solid present just before filtering the product, the slurry containing the crystals should be cooled in an ice bath that contains only crushed ice.

well in order to answer this question you have to provide more information < 3

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
