Firstly, only iron rusts. Other metals are said to corrode, but either is a chemical change.
Yes, rusting/corrosion is oxidation of the metal and is a chemical 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.
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.)
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Tarnishing is a chemical change as it involves a reaction with the metal's surface, often due to exposure to air or moisture. Rusting is also a chemical change, specifically the oxidation of iron in the presence of oxygen and water. Both processes result in the formation of new compounds on the surface of the material.
Metal rusting (corrosion) is a chemical change.
Rusting is the oxidation of a metal and is an example of a chemical change.
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.
a 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
Yes
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
Yes, metal rusting is a chemical change in matter. It involves the metal reacting with oxygen in the presence of moisture to form a new compound (rust), which changes the chemical composition of the metal.
Rusting is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). It results in the formation of a new substance with different chemical properties than the original iron.
Is an example of chemical change, reacting to air
I don't think it is. It's a chemical change.
no rusting iron is not a physical change it is a chemical change
