How does connecting a metal like iron with a wire to a metal that is easier to oxidize like zinc help prevent corrosion of the iron?
A)The other metal is oxidized instead and the electrons travel to the iron,keeping it from oxidizing.
B)The other metal absorbs the electrons from the iron,which keeps the iron from undergoing oxidation.
C)The wire is acting as an oxidant and keeps the two metals from undergoing other chemical reactions.
D)There is no salt-bridge,so there is no reaction between the two metals.
E)The other metal is oxidized and adsorbs all the oxidant,keeping it away from the iron.

Connecting a metal like iron with a wire to a metal that is easier to oxidize like zinc creates a galvanic cell. In this cell, the zinc acts as an anode and is oxidized, releasing electrons. These electrons travel through the wire to the iron, which acts as a cathode. The iron gains electrons and is protected from undergoing oxidation. Therefore, the other metal (zinc) is oxidized instead and the electrons travel to the iron, keeping it from oxidizing.
