Because it is a chemical change.
The iron(of the nail) is combined, chemically, with oxygen (air).
4Fe(s) + 3O2(g) == water==> 2Fe2O3(s) [rust]
What else can I help you with?
Is a nail rusting a physical or chemical chnage?
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.
Is a rusty nail chemical weathering?
Rusting is oxidation, a chemical reaction.
Is a rusty nail physical or a chemical change?
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.
Is freezing of water evaporation of gasoline and rusting a nail a physical change?
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.
Is letting a nail rust a physical or 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.
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
Is a nail rust is a chemical?
Yes, a rusting nail is an example of the chemical change oxidation.
Is a nail rusting a pysical change?
No, rusting is oxidation, a form of chemical change.
Is a nail rusting a physical or chemical chnage?
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.
Is a rusty nail chemical weathering?
Rusting is oxidation, a chemical reaction.
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.
Is a rust forming on an iron nail chemical or physical?
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.
How is a rusting a nail a chemical change?
Rust is a chemical reaction called oxide. When a nail rust, the chemical change is related to the reaction of the metal and oxygen.
What happens when an iron nail and a chemical to absorb water vapour?
When an iron nail comes in contact with a chemical that absorbs water vapor, such as silica gel or calcium chloride, the chemical will absorb the moisture from the air around the nail. This helps prevent the nail from rusting, as rusting is a chemical reaction that occurs when iron comes in contact with water and oxygen. The chemical desiccant helps keep the nail dry and prevents the conditions necessary for rusting to occur.
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 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.
