Is rust an example of a chemical change or a physical change?
rusting is oxidation, so it is definitely a chemical change
Is an old garden rake that is rusting a physical change?
No. It is chemical change because that rust will never be a metal again. A chemical change is a change that is irreversible. ( Ex. Your rake ( that rust will never be a metal again.) A physical change is a change that still has the same compound. Ex. sand ( rocks, just littler.)
Is sanding rust off a bike a physical or chemical change?
Sanding rust off a bike is a physical change because it does not alter the chemical composition of the rust or the metal underneath. It only changes the physical appearance by removing the rust layer mechanically through abrasion.
Is the tendency of iron to rust physical or chemical?
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
Is letting a nail rust a physical or chemical change?
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
What is rust an example of a physical or chemical change?
Chemical change.
What is an example of a chemical change for iron?
rust is a chemical change for iron
Is a nail rust is a chemical?
Yes, a rusting nail is an example of the chemical change oxidation.
Is rust an example of a chemical change or a physical change?

What property is an example of rusting?
It's an example of a chemical change. Rusting is a chemical process by which iron metal reacts with oxygen in the air to produce iron oxide, otherwise known as rust. A chemical change means you end up with something you didn't have before. Every chemical reaction has an equation associated with it, and the equation for rusting iron is:4Fe + 3O2 --> 2Fe2O3
Does rust from a chemical change or a physical change?
Rusting is a chemical change.
Is rust an example of a physical change or a chemical change?
It is an example of chemical change which cannot be reversed. In this change, Iron oxidizes under the presence of oxygen and moisture. The reaction is called a reduction-oxidation, or redox, reaction.
Is iron turned into rust a physical or chemical change?
Chemical change.
Is an old garden rake that is rusting a physical change?
No. It is chemical change because that rust will never be a metal again. A chemical change is a change that is irreversible. ( Ex. Your rake ( that rust will never be a metal again.) A physical change is a change that still has the same compound. Ex. sand ( rocks, just littler.)
How is a rusting a nail a chemical change?
Rust is a chemical reaction called oxide. When a nail rust, the chemical change is related to the reaction of the metal and oxygen.
