Which best identifies why the rusting of an iron nail in the presence of water and oxygen is an oxidation-reduction reaction?

Answer 1

Evidence of a chemical reaction from the rusting of an iron nail is the formation of brown Iron Oxide. The oxidation of iron is a chemical reaction.
Rust is iron oxide. The presence of rust indicates that the iron in the nail has oxidized, which is a chemical reaction.

Answer 2

Rust is iron oxide. The presence of rust indicates that the iron in the nail has oxidized, which is a chemical reaction.

Answer 3

The rusting of an iron nail involves the transfer of electrons from iron atoms to oxygen molecules. Iron atoms lose electrons (oxidation) to form iron oxide (rust), while oxygen molecules gain electrons (reduction) to form hydroxide ions. Overall, this transfer of electrons between iron and oxygen is known as an oxidation-reduction reaction.

Answer 4

It looks like your question is in a multiple choice format, and without the possible answers it is hard to know what you are looking for.
The most obvious sign of rusting is a colour change - red-brown patches of iron oxide will appear on the nail.

Answer 5

Rust is a product of the oxidation of iron. The reaction is as follows: Fe2+(aq) + 2OH-(aq) => Fe(OH)2

Answer 6

The oxygen and iron react and combine to form iron oxide, also called rust, which is the evidence of the chemical reaction.

Answer 7

it is rather pornography

Answer 8

Change of colour.

Answer 9

Iron loss electrons.

Answer 10

Yes, rust is iron oxides.
