chemistry plz help to answer this question​

Answer 1

Answer:

one factor is moisture

rest I don't remember

in coastal regions due to this reason only copper nails are preferred to iron nails

one measure could be electroplating of iron with nickel or other non rusting metal

and another measure could be to use paint as it cuts the supply of moisture or coating it with wax

Answer 2

Explanation:

1-Moisture: The corrosion of iron is limited to the availability of water in the environment. ...

Acid: if the pH of the environment surrounding the metal is low, the rusting process is quickened. ...

Salt: Iron tends to rust faster in the sea, due to the presence of various salts.

2-Copper nails are used in coastal regions more than iron nails because iron rust easily but copper do not rust easily.Galvanised nails are used in coastal areas.

3-Iron can be prevented from rusting by preventing contact with water or humidity. Dry iron simply won't rust. You have to have some moisture. To prevent this contact, the iron can be plated with a non corroding metal like nickel or chrome
