Feb 15, 2020 Rusting of iron. Subsequently, one may also ask, what is an example of a chemical change that can be reversed Because chemical changes produce new substances, they often cannot be undone. For example, you cant change ashes from burning logs back into wood. Some chemical changes can be reversed, but only by other chemical changes.

How is the rusting of iron a similar reaction to burning

Mar 18, 2021 The rusting of iron is a chemical process. It occurs when iron and oxygen go through a chemical reaction similar to burning, or combustion. The rusting of iron is a much slower process, but it still gives off energy. Its just that it releases energy so slowly that you

What Causes Rust to Form The Family Handyman

What Causes Rust to Form The Family Handyman

Nov 24, 2020 Oxidation Reaction. Rust results from a reaction called oxidation, in which iron reacts with water and oxygen to form hydrated iron III oxide. Essentially, the metal is naturally returning to its unrefined state. Learn how to remove rust with electrolysi s. Because iron and oxygen have opposite charges, they gravitate toward each other.
