Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
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.
Is car rusting a chemical change?
Because rust forms when Iron reacts with Oxygen in the atmosphere to produce Iron oxide. Rust is a different chemical compound, with different chemical properties from either of the two chemical elements which formed it. So, a chemical change has obviously taken place.
Is dissolving steel into acid a chemical change?
no, its physical change :)
What is the Chemical equation for rusting steel?
A basic equation for the formation of rust is 4Fe + 3O2 --> 2Fe2O3
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
Is there a chemical or physical change when a bicycle rusts in the rain?
Rusting is a chemical change, as steel/iron turns into iron oxide.
Is steel wool physical or chemical change?
When the steel wool burns, it is oxidized and thus this is a chemical change.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Is melting steel a chemical or physical change?
Physical
Is a piece of steel rusting a chemical reaction?
Yes. Rusting is a chemical reaction between iron and oxygen.
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.
Is magneting steel physical or chemical change?
Magnetizing a piece of steel, a needle for example, is a physical change, for it causes the spin of a group of electrons to be co-alignedrather then randomly oriented. The chemical composition of the steel is unchanged.
Corrosion of bicycle frame?
That'd be a chemical change, as steel/iron turns into iron oxide. Usually called rusting, or corroding.
Is magnetizing steel a physical change or chemical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
Is magnetism steel a physical change or chemical change?
physical, just the aligning of magnetic domains what were previously random in orientation.
What is an example of a physical change and a chemical change for iron?
Physical change: bending. Chemical change: Rusting (oxidation). An example of both in one item: A wrought iron fence was heated and bent into a decorative pattern. After 20 years, the fence shows evidence of deep rusting, especially on decorative curves.
