Batteries are galvanic cells. What happens to ϐ cell as a battery discharges? Does a battery represent a system at equilibrium? Explain. What is ϐ cell when a battery reaches equilibrium? How are batteries and fuel cells alike? How are they different? The U. S. space program uses hydrogen–oxygen fuel cells to produce power for its spacecraft. What is a hydrogen– oxygen fuel cell?
Answer to relevant QuestionsA fuel cell designed to react grain alcohol with oxygen has the following net reaction: C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l) The maximum work 1 mole of alcohol can yield by this process is 1320 kJ. What is the ...Consider the following galvanic cells: For each galvanic cell, give the balanced cell equation and determine ϐo. Standard reduction potentials are found in Table 11.1. Table 11.1 Consider the standard galvanic cell based on the following half reactions Cu2+ + 2e- → Cu Ag+ + e- → Ag The electrodes in this cell are Ag(s) and Cu(s). Does the cell potential increase, decrease, or remain the same ...You have a concentration cell with Cu electrodes and [Cu2+] = 1.00 M (right side) and 1.0 × 1024 M (left side). a. Calculate the potential for this cell at 25oC. b. The Cu21 ion reacts with NH3 to form Cu(NH3)42+, where the ...What is the focus of a usage variance?
