Yes, because the chemical reaction of rust is next to impossible to get the iron, water and oxygen back from the iron oxide it creates by rusting, and its like baking a cake is a chemical reaction, once the cake is a cake you can't get the eggs or sugar back. The rust also makes the nails weak and flimsy, this is why we shouldn't use nails if they are rusted, especially large structures. A way you can tell its a chemical reaction is that the color changes and the appearance changes.
Iron combines with oxygen to form iron oxide (rust). Water may serve as a catalyst in this process, as iron does not appear to rust rapidly in dry, oxygen rich air. You can accelerate the rusting process even faster by placing iron in acetic acid (vinegar).
The chemical change occurs when iron combines with oxygen to form iron oxide.

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.
no rusting iron is not a physical change it is a chemical change
It's not the rusty bike it's the rusting of the bike. rust forms in a process called oxidation, or when iron comes in contact with oxygen. Also one reason you can tell it's a chemical change is when you can't reverse the process. Or when it involves changing the chemical compound.
Rusting is a reaction which combines molecules to form other molecules: metal + oxygen -> rust. The definition of a chemical reaction is molecules turning into other molecules, so rusting is a chemical reaction.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
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
No, rusting is oxidation, a form of chemical change.
Yes, a rusting nail is an example of the chemical change oxidation.
Rust is a chemical reaction called oxide. When a nail rust, the chemical change is related to the reaction of the metal and oxygen.
freezing water and evaporation is physical-only change in state of matter. rusting nail is chemical-alters composition of substance
I am quite sure that rust is a chemical change. Rust is caused when oxygen atoms begin bonding with the iron in the nail, which makes it a compound instead of a pure element.
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.
Chemical
A nail rusting is a chemical change. The iron in the nail reacts with water and oxygen to produce rust, a compound with the chemical formula Fe3O2.nH2O.
It is a chemical change because the molecular nature is changed; iron become after oxidation an iron oxide.
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.
