What is a chemical cell?
A device that produces electricity from a chemical reaction.
What is a battery?
Two or more chemical cells connected in series.
How does a chemical cell work?
By transferring electrons in a redox reaction.
What type of reaction occurs in a cell?
Redox reactions.
What is the role of an electrolyte in a cell?
It allows ions to move and conduct electricity.
Why does a cell stop producing electricity?
The reactants are used up.
What determines the voltage of a cell?
The difference in reactivity of the electrodes.
Why do non-rechargeable batteries eventually stop working?
The chemical reactions are irreversible.
Name a common rechargeable battery.
Lithium-ion battery.
What is the advantage of rechargeable batteries?
They can be reused multiple times.
What is the disadvantage of non-rechargeable batteries?
They contribute to waste and environmental pollution.
Write a redox reaction that occurs in a cell.
Zn+Cu2+→Zn2++Cu
Why are alkaline batteries better than traditional ones?
They last longer and provide more energy.
What is the role of the electrodes in a cell?
To conduct electricity and participate in redox reactions.
How does connecting cells in series affect the voltage?
The voltages add up.
