Which best identifies why the rusting of an iron nail in the presence of water and oxygen is an oxidation-reduction reaction? water is a reactant. electrons are transferred. nonmetals and a metal are involved. energy is released.

The best answer on this particular answer would be, "The electrons are transferred."

Answer : The correct option is, Electrons are transferred.

Explanation :

Iron rusting : It is a chemical process in which the an iron nail react with water and oxygen to give iron oxide as a product. Rusting of iron is an oxidation-reduction reaction in which iron losses electrons to oxygen atom.

Oxidation-reduction reaction : It is a reaction in which oxidation and reduction reaction occur simultaneously.

The balanced chemical reaction for rusting of irons is,

Half reactions of oxidation and reduction are :

Oxidation :

Reduction :

From this reaction we conclude that the electrons are getting transferred from iron to oxygen.

Hence, the correct option is, Electrons are transferred.

i hope that ! =)

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
