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.
Yes, rust forming on an iron nail is a chemical change. It involves the oxidation of iron in the presence of oxygen and water to form iron oxide (rust), which has different chemical properties than the original iron.
Chemical change, oxygen binds with iron.
Tarnishing an iron nail is a chemical change because it involves a reaction between iron, oxygen, and moisture in the air that forms iron oxide (rust) on the surface of the nail. This chemical reaction alters the composition of the nail, resulting in a new substance (iron oxide) being formed.
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)

The chemical change of pizza, paper, and an iron nail would lead to a new substance(s) being formed with different properties than the original materials. A physical change, on the other hand, involves a change in the physical state or appearance of a substance without forming a new substance.
physical
Because the Iron in the nail is no longer just iron but oxidation plus iron, a physical change to the nail would be to cut it in-half.
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.
Rusting of a nail is a chemical change. It involves a reaction between iron in the nail and oxygen in the air to form iron oxide (rust), which has different chemical properties compared to the original iron.
Heating is a physical change.
Yes, rust forming on an iron nail is a chemical change. It involves the oxidation of iron in the presence of oxygen and water to form iron oxide (rust), which has different chemical properties than the original iron.
Rust forming on an iron nail is a chemical reaction rather than a mixture. Rust is a compound made up of iron oxide that results from the reaction of iron with oxygen and water in the presence of air.
The rusting of a nail is a chemical change. This is because the iron in the nail reacts with oxygen in the air to form iron oxide, which is the rust. This process involves a chemical reaction and results in a change in the composition of the nail.
Chemical change, oxygen binds with iron.
