Given that the drift mobility of electrons in copper is 32 cm2 v–1 s–1 , and using values of the electrical conductivity, atomic weight, and density of copper from c& r, compute the number of conduction electrons per atom in copper. (hint: compute the number of atoms per unit volume in copper, and then compare this to the number of conduction electrons per unit volume (i. e., the carrier density n) computed from copper’s electrical conductivity.) b) in compounds, copper is known to exhibit two common oxidation states, +1 and +2. discuss whether this fact is consistent with your answer for part a).

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

what is the question here. i think you messed up.
