- An alloy made up of tin and copper is prepared by simultaneously electroplating the two metals from a solution containing Sn(NO3)2 and Cu(NO3)2.If 20.0% of the total current is used to plate tin, while 80.0% is used to plate copper, what is the percent composition of the alloy?arrow_forwardWhen an aqueous solution of CuSO, is electrolyzed copper metal is deposited. If a constant current was passed for 5.00 h and 404 mg of Cu (63.546) metal was deposited, what was the current?arrow_forwardHow many grams of cobalt metal will be deposited from a solution that contains Co2+ ions if a current of 0.974 A is applied for 67.4 minutes?arrow_forward
- A metallic object to be plated with copper is placed in a solution of CuSO.. What mass of copper will be deposited if a current of 0.22 amp flows through the cell for 1.5 hours?arrow_forwarda current of 3.25A is passed through a Ni(NO3)2 solution how long in hours would this current have to be applied to plate out 5.40g of nickel? give answer to the nearest hundredtharrow_forwardA current of 0.46 A was passed through a copper (II) sulfate solution using copper electrodes for 16 minutes and 25 seconds. Calculate the mass of copper deposited on the cathode.arrow_forward
- 3 (a) Liquid NH3 is subjected to electrolysis. One of the half-reactions is 2 N3- → N2 + 6 e How many faradays of electricity are required to produce 4.12 L of N2 at 744 torr and 28 °C? (b) If a current of 2.50 A is used, how many hours will it take to carry out the electrolysis in part (a)?arrow_forwardGiorno Giovanna likes golden stuff. However, since he is currently broke, he has to settle for objects with gold plating. He decided to deposit 55.00 g of gold over an iron medallion by electroplating it from a solution containing Au3+ ions while utilizing a constant current of 2.225 A. (MM of gold= 196.97 g/mol) What is the total amount of charge needed in order to complete the process?arrow_forwardHow many seconds are required to deposit 0.262 grams of chromium metal from a solution that contains Cr3+ ions, if a current of 1.08 A is applied. _______sarrow_forward
- a solution containing a metal ion is electrocyzed by a current of 5 A. after 10 minutes, 1.19g of the metal is plated out A.)what is the metalarrow_forwardA Cr3+1aq2 solution is electrolyzed, using a current of 7.60 A. What mass of Cr(s) is plated out after 2.00 days?arrow_forwardAn aqueous solution of an unknown salt of ruthenium Is electrolyzed by a current of 2.70A passion for 20.0min. If 1.132g of Ru is produced at the cathode, what js the charge on the ruthenium ions in solution?arrow_forward
