How do you know rusting on a nail is a chemical change?
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.
WHY A RUSTING NAIL IS AN IRREVERSIBLE CHANGE?
A rusting nail undergoes a chemical reaction between iron, oxygen, and moisture, resulting in the formation of iron oxides, commonly known as rust. This process alters the nail's original composition and structure, making it fundamentally different from its initial state. Once rusted, the nail cannot revert to its original metallic form without extensive and impractical methods, such as electrolysis. Consequently, rusting is classified as an irreversible change due to the permanent transformation of materials involved.
Is Rust forms on a nail left outside a chemical change?
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.
What chemical property is shown when rust forms on a nail?
When rust forms on a nail the dark brown colour is the characteristics of rusting.
A nail rusts is a chemical or physical change?
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.
Is a rusty nail reversible?
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.
How do you know rusting on a nail is a chemical change?
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.

Is a nail rusting a physical or chemical?
A nail rusting is a chemical change.
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
Why is a rusting nail a chemical chance?
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.
Is rusting an irreversible cause?
Rusting is an irreversible process.
Is a nail rusting a pysical change?
No, rusting is oxidation, a form of chemical change.
Is a nail rusting reversible?
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.
Is a nail rust is a chemical?
Yes, a rusting nail is an example of the chemical change oxidation.
Does the weight of a nail change after rusting?
Yeah, it does and it becomes more
Why is rusting nail chemical change?
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.
