Final answer:
In a zinc-carbon dry cell, the anode is zinc (Zn) and the cathode is manganese (IV) oxide (MnO2) . The correct answer is option 1) Zn, MnO₂
Step-by-step explanation:
In the zinc-carbon dry cell, the anode is a zinc container that serves as the site of oxidation, while the cathode is a carbon rod that serves as the site of reduction.
This means that the anode is where zinc is oxidized from solid zinc (Zn) to zinc ions (Zn²⁺), releasing electrons in the process. The cathode involves a reaction with manganese (IV) oxide (MnO₂) which is reduced in the process.
Therefore, the correct answer to the question is 1) Zn, MnO₂.
