Step 1: Convert the time from minutes to seconds. t = 35 minutes × 60 seconds1 minute = 2100 seconds Step 2: Calculate the total quantity of charge (Q) passed using the formula Q = I × t. Q = 0.5 A × 2100 s Q = 1050 C Step 3: Determine the moles of electrons (n_e) transferred using Faraday's constant (F = 96485 C/mol e^-). n_e = (Q)/(F) n_e = 1050 C96485 C/mol e^- n_e ≈ 0.010882 mol e^- Step 4: Use the stoichiometry of the copper deposition reaction to find the moles of copper formed. The reduction of copper ions is: Cu^2+ + 2e^- Cu This means 2 moles of electrons are required to deposit 1 mole of copper. Moles of Cu = Moles of e^-2 Moles of Cu = 0.010882 mol e^-2 Moles of Cu ≈ 0.005441 mol The moles of copper formed is 0.005441 mol. That's 2 down. 3 left today — send the next one.
