Iron oxidizes (rusts) when exposed to oxygen. Paint coats the iron and keeps oxygen away from it, preventing rust. However, paint does not last forever. After awhile it wears off or cracks or flakes off and no longer protects. Repainting restores the coating and the protection.

What is the relation between metallic iron and total iron in sponge iron?
Metallic iron refers specifically to the iron that is in its metallic form in sponge iron. Total iron in sponge iron includes metallic iron as well as any iron present in other forms such as iron oxides. Therefore, metallic iron is a subset of total iron in sponge iron.
What happens to iron when iron oxide becomes elemental iron?
When iron oxide is reduced to elemental iron, iron atoms gain electrons to form metallic iron. This process involves the removal of oxygen atoms from the iron oxide, resulting in the formation of pure iron without any oxygen content. The reduction reaction converts iron from a compound state (iron oxide) to its elemental form (pure iron).
What is an example of a solution iron rust and iron ore am iron alloy iron metal?
An example of a solution involving iron rust (iron oxide) is when iron reacts with oxygen and moisture in the air, forming rust, which is a hydrated form of iron(III) oxide. Iron ore, such as hematite or magnetite, is a natural mineral from which iron can be extracted. An iron alloy example is steel, which is made by combining iron with carbon and other elements to enhance its strength and durability. Finally, iron metal is the pure form of iron obtained through smelting iron ore in a blast furnace.
How do you calculate total iron) in sponge iron if metallic iron is known?
To calculate total iron in sponge iron when the metallic iron content is known, you can use the formula: Total Iron = Metallic Iron × (1 + Iron Oxide Ratio). The iron oxide ratio reflects the proportion of iron present in the form of oxides, which can vary based on the production process. For example, if you have 90% metallic iron and an oxide ratio of 0.1, the total iron would be calculated as 90% × (1 + 0.1) = 99%.
