When iron rusts, it is a chemical change. The substance that is produced (the rust) is a completely new substance. Therefore, the iron has changed chemically, and not just physically, like being melted into a different shape. It's chemical structure has been altered.
Iron rusting is a chemical change.
Chemical change, oxygen binds with iron.
Rusting is a chemical process, an oxidation reaction.
The color change of iron wire when it rusts is a chemical change because it involves a reaction with oxygen in the air to form iron oxide. This new substance has different properties than the original iron.
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
Its is chemical as
Iron rusting is a chemical change.
Chemical change, oxygen binds with iron.
Because it is not a physical change it is a chemical change.
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Rusting is a chemical change, as steel/iron turns into iron oxide.
Rusting is a chemical process, an oxidation reaction.
Chemical reaction from water
A physical change refers to a change in appearance or state that does not alter the chemical composition of the substance. When milk sours, it undergoes a physical change because its appearance and taste change, but the molecules remain the same. Similarly, when an iron nail rusts, it is a physical change because the iron's appearance changes as it forms rust, but the chemical composition of the iron is not altered.
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
