Is rusting a chemical or physical property?
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
Why is a car rusting a physical change?
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
List 3 chemical properties?
Three chemical properties are reactivity, flammability, and oxidation state.
Is a silver knife and fork tarnish when they are exposed to air for several weeks a chemical or physical change?
Tarnishing of silver is the same process as rusting of steel . . . they are both chemical processes involving the formation of compounds with oxygen.
5 examples of chemical properties?
- reactivity - flammability - aptitude to explode - electronegativity - pH - corrosion - polymerization - thermal stability - solubility - oxidation aptitude
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.
What are the physical and chemical changes in metal?
Physical Changes in metal are: melting bending and rusting
Is a rusting bicycle a chemical changes or a physical change?
physical change
Is rusting a chemical or physical property?

What is the 3 chemical properties?
I don’t know the answer
Why does a substance decompose?
A substance decomposes as a result of chemical changes in it such as rusting, tarnishing, decaying with exposure to air and affect of micro-organisms etc.
Why is a car rusting a physical change?
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
Is rusting a nail a physical change or chemical change?
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
Does the paint on a car help prevent from physical changes?
No but it helps prevent chemical changes like rusting.
List 3 chemical properties?
Three chemical properties are reactivity, flammability, and oxidation state.
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.
