Electron transfer between redox centers in proteins is controlled by electron tunneling. If we model a bound electron as in a box, if the distance between the redox centers is 0.582 nm and the tunneling constant C =C= 12.1 ~\text{nm}^{-1} nm −1 , what is the tunneling coefficient for electron tunneling?

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ
