Practice Problems
A concentration cell made of two Au/Au3+ half-cells serves as the foundation for the construction of a rechargeable battery. Each half-cell has a 1.5 L capacity, and there are 2.05 M and 1.4x10−3 M Au3+ concentrations inside each half-cell. How much gold is plated onto the cathode when it is operated at 1.9 A for 6.7 hours?
The reduction of lead and the oxidation of calcium creates a theoretical battery. If there are 0.55 M of Pb2+ and 0.015 M of Ca2+ in a 1.0-liter half-cells initially, calculate the voltage of the battery after giving off 3.0 A for 4.5 h?
The lithium cobalt oxide in a discharging lithium-ion battery __________ for every lithium-ion inserted.a. Expandsb. Contractsc. None of the above
Which statement is correct regarding a zinc-carbon battery with zinc and manganese oxide (MnO2) electrodes? a. It has an energy density most similar to a nickel metal hydride battery b. It has an energy density most similar to an energy Li-ion battery c. It has an energy density most similar to a Lead-acid battery
The unit used to express the capacity of batteries is milliamp-hours (mAh). A fresh alkaline battery has a normal capacity of 2500 mAh and starting voltage of 1.50 V. When the battery has delivered its rated capacity, its voltage decreases to 0.75 V during discharge. Estimate the total maximum electrical work that the battery could perform during discharge if we assume that voltage declines linearly as current is withdrawn.Show More
