Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What is rust composed of?
Rust (in its "regular" red form) is an iron oxide called iron(III) oxide. It's formula is Fe2O3, and we call it ferric oxide or hematite. And that's different from iron (II) oxide FeO, or iron (II,III) oxide Fe3O4. There are three basic forms of oxidized iron, and there they are. Wikipedia has more information, and a link to their post is provided below. Rust is basically ferric oxide caused by the action of air, or to be more precise, the action of oxygen and water droplets on iron.
Why is rusting a chemical change?
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.
What two substances are need to rust Iron?
ANSWER:oxygen and water
Is the ability to rust a chemical property?
Rust is Iron Oxide which has accumlated on top of the iron. The top layer of the iron, when exposed to moisture or water, reacts with the oxygen in the air to form rust. Rust can also form when Iron is exposed to a strong oxidizer or acids. But rust is not a chemical property of iron, it's in fact a completely different compound which used to be iron before reacting with oxygen.
What kind of change causes iron to rust is a physical change?
The process of iron rusting is a chemical change, not a physical change. It involves a chemical reaction between the iron, oxygen, and water in the environment, resulting in the formation of iron oxide (rust).
Is rust of iron a chemical change?
Oxygen reacts with the iron to make it rust.
What kind of change of rusting of iron?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
What is an example of a chemical change for iron?
rust is a chemical change for iron
What kind of change is rust?
Rust is a chemical change.
What is the chemical change of iron?
it rust.
What type of change is rust formed into iron after exposure to air?
The formation of rust when iron is exposed to air is a chemical change. This process, known as oxidation, occurs when iron reacts with oxygen in the presence of water to form iron oxide, which is what we see as rust.
Why is rust forming on a nail not a pysical change?
It is not a physical change because rust is no longer iron, but is iron oxide, a completely different substance.
What element turns into rust after a chemical change?
Iron. Iron, when exposed to oxygen, turns into iron oxide - better known as rust.
Is the tendency of iron to rust physical or chemical?
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
What is an example of a physical change in iron?
Rust
Is rust forming on an iron nail a chemical 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.
