Gold (atomic mass = 197.0) is plated from a solution of chloroauric acid, HAuCl4; it deposits on the cathode. Calculate the time it takes to deposit 0.68 gram of gold, passing a current of 0.10 amperes. (1 faraday = 96,485 coulombs) A.56 minutes B.28 hours C.19 minutes D.2.8 hours E.none of these
Gold has an atomic mass of 197 u, a density of 19.3 x 10° kg/m³, a Fermi energy of 5.54 eV, and a resistivity of 2.04 x 10-8Q: m. Estimate the mean free path in atom spac-ings between collisions of the free electrons in gold under the assumption that each gold atom contributes one electron to the electron gas.
Gold (atomic mass = 197.0) is plated from a solution of chloroauric acid, HAuCl4; it deposits on the cathode. Calculate the time it takes to deposit 0.34 gram of gold, passing a current of 0.10 amperes. (1 faraday = 96,485 coulombs)
