Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
Is addition of iron to dil . acid a physical change or chemical change?
Adding water (which is not a reactant) is a physical process.
Is rusting of an iron fence physical change?
yes. rust is a chemical change that occurs when you mix iron, air, and water. it reacts with the iron and actually erodes it. a n example of a physical change would be the bending or cutting of iron.
What are some examples of simultaneous chemical and physical changes?
Physical change:the change in which no new substance only undergoes change in its shape appearance or states is formed known as physical change.Examples: freezing of water, tearing a paper, etc.
Is iron left outside to rust a chemical or physical change?
The process of iron rusting is a chemical change. This is because the iron reacts with oxygen in the presence of water to produce iron oxide, a new substance with different chemical properties than the original iron.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with iron.
Is metal roasting a chemical or physical change?
The rusting of metal is a chemical change and not a physical change. This is because iron and water react to form a compound called iron oxide.
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).
What is a example of a physical change of iron?
Melting is a physical change of iron.
Is addition of iron to dil . acid a physical change or chemical change?
Adding water (which is not a reactant) is a physical process.
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
Is rusting of an iron fence physical change?

Is melting a iron rod a physical change?
Melting an iron rod is a physical change
When iron rusts is that a chemical or physical change?
It is a chemical change, the iron is being oxidized and forming rust. A good way to think about it is if you can undo it then it is a physical change. For example if you put salt in water, that is a physical change because you can boil off the water and get the salt back. Source: AP Chemistry
Rusting iron is it physical or chemical change?
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
Is iron rusting a chemical or physical change?
Iron rusting is a chemical change: oxidation of the metal by oxygen in the air or water. When iron 'rusts' it oxidises. This is a chemical change, a physical change is when a molecule changes state, for example iron melting and going from a solid to a liquid.
Is car rusting physical change?
No, a car rusting is a chemical change because a new substance is formed. Iron will react with oxygen (found in water) forming iron oxide. The product, iron oxide, has different properties from both iron and oxygen. A "chemical change" describes any reaction where a new substance is formed. However, if a substance just changes forms, it is a physical change. For example, water freezing is a physical change.
