Answer 2

The major problem associated with the use of iron for various purposes is that iron is wasted by rusting in the air and water.

Explanation:

• Iron and steel are some widely used metals to make various objects.
• However, the major problem with the use of iron is rusting.
• Rusting refers to the process of rust. It is formed by various iron oxides.
• The process is known to be redox. In this process when oxygen comes in contact with iron-containing water; then a formation of iron oxides takes place.
• This forms rust on the surface of iron metal.
• Therefore, the major problem with iron is that it gets wasted by rusting in the air and water.
