Because you can't 'unrust' a nail
Rusting on a nail is a chemical change because it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide. This process is irreversible and results in a change in the chemical composition of the nail.
Rusting is always a chemical change because it is an irreversible change. The iron nail gets oxidized due to the moisture and oxygen in the atmosphere and you can't get that nail back to its original form. An oxidation reaction is a chemical change.
When rust forms on a nail the dark brown colour is the characteristics of rusting.
The rusting of a nail is a chemical change because it involves a reaction between the iron in the nail and oxygen in the air to form iron oxide (rust). This results in a new substance being formed with different properties than the original nail.
because the chemical composition of the nail is changed, forming a new substance (the rust)
Surface rusting may be removed without weakening the metal nail too much. A badly rusted nail may not have enough metal left to be strong enough to still be useful. Therefore, irreversible change depends on the depth the rusting has reached.
Rusting on a nail is a chemical change because it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide. This process is irreversible and results in a change in the chemical composition of the nail.
A nail rusting is 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
A rusting nail is a chemical change because the iron in the nail is reacting with oxygen in the air to form iron oxide (rust), changing the composition of the nail. This process is irreversible and involves a chemical reaction.
Rusting is an irreversible process.
No, rusting is oxidation, a form of chemical change.
I'm not sure what you mean by "reversible" When iron rusts some of the iron it changed to iron oxide and thus part of the nail would be lost, but if discovered in time the rusting can be stopped and prevented from continuing.
Yes, a rusting nail is an example of the chemical change oxidation.
Yeah, it does and it becomes more
A rusting nail is the oxidation of iron, in which the iron in the nail and the oxygen in the air react to form a new substance, iron oxide, with different properties from the iron and the oxygen.
permanent- you are changing the chemicals in the iron when it rust
