Concept explainers
(a)
Interpretation:
Using the given data, a graph has to be prepared.
Concept introduction:
Battery: A battery is a device consisting of one or more cells that can be produce a direct current by converting by chemical energy into electrical energy.
Rechargeable battery work because they use reaction are reversible, while non-rechargeable battery they use reactions are non-reversible.
(b)
Interpretation:
The answer for the given question has to be justified using the graph.
Concept introduction:
Electrochemical cell is a device capable of converting chemical energy into electrical energy or induces chemical energy by electrical energy. In the galvanic cell spontaneous redox reaction takes place. Redox reaction means the reaction in which the oxidation state of the atoms changes due to the occurrence of both reduction and its complementary oxidation reactions. The element under oxidation reaction loses electron whereas the element in the reduction gains electron.
Battery: A battery is a device consisting of one or more cells that can be produce a direct current by converting by chemical energy into electrical energy.
Rechargeable battery work because they use reaction are reversible, while non-rechargeable battery they use reactions are non-reversible.

Chemistry In Context
- An aqueous solution of an unknown salt of gold is electrolyzed by a current of 2.75 amps for 3.39 hours. The electroplating is carried out with an efficiency of 93.0%, resulting in a deposit of 21.221 g of gold. a How many faradays are required to deposit the gold? b What is the charge on the gold ions (based on your calculations)?arrow_forwardFossil fuel, nuclear, and hydroelectric power plants all require a transmission network to transport electricity from where it is generated to where it is used. MCFCs, with their smaller size and portability, can be placed much closer to where the power is needed, reducing the need for transmission lines. With this in mind, explain why MCFCs may have a greater advantage for providing power in developing countries versus in developed countries.arrow_forward9.69 How are the roles of transmission substations and distribution substations in the electrical grid similar? How are they different?arrow_forward
- 13.104 (a) What happens when a current is passed through a solution of dilute sulfuric acid to carry out electrolysis? (b) A 5.00-A current is passed through a dilute solution of sulfuric acid for 30.0 min. What mass of oxygen is produced?arrow_forwardAn electrolysis cell for aluminum production operates at 5.0 V and a current of 1.0 105 A. Calculate the number of kilowatt-hours of energy required to produce 1 metrication (1.0 103 kg) of aluminum. (1 kWh = 3.6 106 J and 1 J = 1C V)arrow_forward
