Why are rusting and tarnishing examples of corrosion?
Rusting and tarnishing are examples of corrosion because they involve the chemical reaction of a material with its environment, leading to degradation of the material's surface. In rusting, iron reacts with oxygen in the presence of water to form iron oxide (rust), while tarnishing involves the reaction of metals with substances in the air, such as sulfur or carbon dioxide, leading to discoloration and degradation of the material's surface.
What does corrison mean?
Corrosion is the deterioration of a material, usually a metal, due to a chemical reaction with its environment. This can lead to rusting, tarnishing, or other forms of degradation.
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
Can you call the corrosion of all metals as rusting?
No. Rust (iron oxide) only occurs in metals containing iron. A couple examples of different types of corrosion are galvanic corrosion and chloride pitting corrosion.
What is rusting Tarnishing and burning?
They are all oxidation. Burning is much faster than the other two and releases large quantities of heat. Rusting and tarnishing are much slower. Tarnishing typically shows a change in color and very little in the way of physical change. Rusting slowly eats away the material as it combines with the oxygen.

What are some examples of corrosion?
Iron and steel rusting is an example of corrosion. Copper pitting or the green patina one sees on copper roofs are also examples of corrosion. Stress Cracking is also considered an example of corrosion.
Why doesn't gold tarnish?
Gold does not tarnish because it is a noble metal, meaning it is resistant to corrosion and oxidation. Its chemical properties make it highly stable and unreactive, preventing it from tarnishing or rusting like other metals.
Is rusting a metal physical change?
Metal rusting (corrosion) is a chemical change.

Does rhodium tarnish or rust?
Rhodium is highly resistant to tarnishing and rusting due to its strong corrosion resistance. It is commonly used as a plating material for jewelry and other items to provide a protective and shiny surface that does not easily react with its surroundings.
