Chemical
Freezing of water and evaporation of gasoline are physical changes because they involve a change in physical state without altering the chemical composition of the substances. Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
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.
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 is oxidation, a chemical reaction.
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.
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

Rusting of a nail is a chemical change as it involves a chemical reaction between the iron in the nail and oxygen in the air to form iron oxide.
because the chemical composition of the nail is changed, forming a new substance (the rust)
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.
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.
Yes, a rusting nail is an example of the chemical change oxidation.
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.
No, rusting is oxidation, a form of chemical change.
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 is oxidation, a chemical reaction.
When rust forms on a nail the dark brown colour is the characteristics of rusting.
