Copper plating was accomplished using either graphite or copper as the electrodes. How would you expect the copper(II) ion concentration of the solution change (i.e. would [Cu2] increase, decrease, or remain the same?) during the plating process if the graphite anode were replaced with a copper one in the electrolysis of CuBr2? Explain your answer 5. Calculate the mass and thickness in mm of the chromium plate on an object if a current of 450.0 mamps were allowed to flow...

(4) Thermodynamic data suggests that copper monohalides (CuX) should exist as polymers in the gas phaso However, scientists have successfully synthesized CuX monomers and characterized them using microwave spectroscopy For Cu Br the J-13 14,J-1415 and J-1516 transitions occurred at 84421.34 MHz, 90449.25 MHz and 96476.72 MHz, respectively. Assuming Cu Br behaves as a 3D rigid rotor, answer the following questions. Note: Absorption frequency (in units of Hz) of a rotational transition (aka peak position in a microwave spectrum) corresponding...

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
