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.
Rusting is a chemical change because the compound you end up with is not the same as the substance you started with. It is the oxidation of metal due to exposure to the air. The most common example would be iron, Fe.
4Fe (s) + 3O2 (g) -> 2Fe2O3 (s)
Evidence of Chemical Reaction -Color Change Substances often change color during a chemical reaction. For example: Gray iron rusts, the product that forms is a rusty/ flaky brown coating. ..so yes. A nail rusting IS a chemical reaction:)
the nails becoming rusty are a cause of the iron reacting with the oxygen in the air and making iron oxide and you cannot change it back, which makes it a 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.
it is a Chemical change because before they are rusty they are perfect and they are a solid brown but over time they change colors because they are getting old
H2O + air + metal = rust
The rusting of iron in the nail to iron oxide is a chemical change.
Iron nails rust when the iron reacts with the oxygen in the atmosphere or in water, forming iron oxide, a new chemical. The chemical reaction is Fe + O2 --> FeO, or Fe + O2 --> Fe2O3.
Rusty nails are chemical change.

Physical, if you are not using any chemicals in the process it is a physical change.

Rusting is oxidation, a chemical reaction.
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.

Heating is a physical 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
hammering a nail is a physical change, this is because the nail changes shape from being long to being short and in a board for example.
rusting of nails is a chemical reaction. iron combines with oxygen to form iron oxide which is rust. water/water vapour acts as a catalysthere.
