Is it true that when iron rusts a chemical change has occurred?
Yes, it is true; rusting is the formation of iron oxides.
Is the reaction of iron with oxygen to form iron oxides a physical or chemical change?
Reaction of iron with oxygen to form iron oxide is an example for a chemical change as iron is getting oxidized to its oxide . The process is known as corrosion and the product is commonly known as rust.See the Related Questions to the left for more information about chemical changes, physical changes, and rust itself.iron rusts is a chemical change because you cant cahnge the way it is now.
Is a car rusting a physical or a chemical?
It's a chemical change; a car rusts because the iron on the car's surface react with oxygen and water to form iron oxides.
Why iron rust is chemical change?
The reason that rust is considered a chemical change is because the "connections" or the bonds of atoms are changed in the process. When atoms "rearrange themselves" by changing the "connections" or bonds to allow different compounds to be formed, as is the case with the formation of rust, a chemical change has taken place.
Which one is a chemical change -rusting of iron or melting of iron?
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
Why rusting of iron is chemical change?
Rusting of iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form a new substance called iron oxide. This process cannot be easily reversed, and the properties of the original iron are changed as a result of the rusting process.
Is an iron nail rusts a phisical change?
It is a chemical change. Oxygen in the air (and sometimes water vapor) combines with the iron to form oxides. The rust is a new chemical with very different properties: it has little strength, can be washed away, and is no longer attracted to a magnet.
