What type of change is rusting of iron ? Explain. |
|
Answer» When substances made of iron are exposed to oxygen and moisture (water), rusting takes place. Rusting removes a layer of MATERIAL from the surface and makes the substance weak. Rusting is a chemical CHANGE. The process of DEPOSITING zinc on the iron to prevent rusting is known as galvanization. A striking example of the use of galvanization is the water pipes USED in HOUSES. Rusting is an example of a chemical change. A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. A chemical change is also called a chemical reaction. |
