To calculate the electromotive force (emf) of the cell, we use the standard electrode potentials of copper and zinc. Step 1: Identify the standard electrode potentials. The standard electrode potential for copper, E^_Cu, is +0.34\,V. The standard electrode potential for zinc, E^_Zn, is -0.76\,V. Step 2: Determine the cathode and anode. The species with the more positive (or less negative) standard electrode potential will be reduced and act as the cathode. Copper has a more positive potential (+0.34\,V) than zinc (-0.76\,V). Therefore, copper will be reduced at the cathode, and zinc will be oxidized at the anode. Step 3: Apply the formula for cell emf. The emf of the cell is calculated using the formula: E_cell = E^_cathode - E^_anode Step 4: Substitute the values and calculate. E_cell = (+0.34\,V) - (-0.76\,V) E_cell = 0.34\,V + 0.76\,V E_cell = 1.10\,V The emf of the cell is +1.10 V. Send me the next one 📸
