To my knowledge, a penny is not a chemical change. No, I think it is instead a coin; a unit of currency, mostly made from zinc and plated with copper. Nothing I'm describing has anything to do with chemical changes.

Is tarnishing of costume jewelry physical of chemical change?
Tarnishing is a chemical change in which the metal is being oxidized.
Is Rust forms on a nail left outside a chemical change?
Rusting is always a chemical change because it is an irreversible change. The iron nail gets oxidized due to the moisture and oxygen in the atmosphere and you can't get that nail back to its original form. An oxidation reaction is a chemical change.
Is corroding metal a chemical change?
Yes. When metal rusts the iron is changed into iron oxide. This type of change is called a redox reaction. The iron is oxidized, meaning is has lost electrons.
Is oxidation an example of a chemical change?
Oxidation is a chemical change. This is a chemical change because it has formed into a new substance and cannot change back! The chemical identity of the metal has been changed and will require some other change to change it back.
If a chemical compound becomes oxidized it?
loses electrons

Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is photosynthesis is chemical or physical change?
ChemicalCO2 is reduced into glucose. Water is oxidized into Oxygen.Also energy transformation occurs. Light energy transforms into chemical energy
Is corrode a physical or chemical process?
Corroding a substance would be a chemical change because it alters the composition of the material being corroded.

Why do penny turn green?
The pennies turn green because they are open to the air, because they contain copper, and because copper turns green when oxidized.
Is a change in shape a clue that indicate a chemical change?
It is a physical change unless it is caught on fire to mold into a different shape then it would be a chemical change. The substance that does change shape does not develop new chemical properties.
What is the chemical composition of corroded or oxidized aluminum?
That depends.
If a chemical compound becomes oxidized it?
loses electrons
