Rusting iron (or steel) is a chemical reaction. It is where iron reacts with water and oxygen to form iron(III) oxide. Fe + H2O + O2 -> Fe2O3.H2O
Note that the equation above isn't balanced.
What else can I help you with?
Is rusting a chemical or physical property?
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
Is rusting a nail a physical change or 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
Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
Is rusting of iron chemical change and why?
Rusting of iron is, indeed a chemical change. The reason is because the iron changes to a different chemical compound, and is no longer iron. It turns into iron oxide. The chemical reaction looks like this: 4Fe + 3O2 ==> 2Fe2O3
Is rusting of an iron fence physical change?
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
Can rusting iron nails be a chemical change?
Rusting of iron is chemical. It is the combination of oxygen with the iron, creating a different chemical: rust or iron oxide.
Is rusting iron a chemical reaction?
Yes, rusting nails is a chemical reaction. I just went over this in chemistry class last week.
Is iron rusting in a charge of chemical?
No, iron rusting is oxidation process
Is rusting of iron a physical or chemical change?
Rusting of iron is a chemical change. It occurs when iron reacts with oxygen and water in the presence of moisture, forming iron oxide (rust). This process involves a chemical reaction that changes the chemical composition of the iron.
Is iron rusting a chemical or physical change?
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.
Is to rust in water a physical property?
Yes, rusting in water is a chemical property. The process of rusting involves a chemical reaction between iron and oxygen in the presence of water to form iron oxide, which changes the composition of the iron.
Is metal rusting a physical change in matter?
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.
