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.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
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.
The rusting of iron is a chemical change because the iron reacts with oxygen in the air to form iron oxide. This process cannot be reversed by physical means and results in a new substance being formed.
Rusting of a screw is a chemical change. It involves a chemical reaction between the iron in the screw and oxygen in the air to form iron oxide (rust).
no its chemical. physical changes is where the object chemical matter is not altered. ex- cuting a piece of paper is physical because you still have a piece of paper but burning the paper is chemical because a chemical change has taken place.
it is a chemical change
no it is a chemical change
chemical
no rusting iron is not a physical change it is a chemical change
Iron rusting is a chemical change.
Rusting of iron is a chemical change because it involves a reaction with oxygen to form iron oxide. Melting of iron is a physical change because it does not involve a change in the chemical composition of the iron.
No. Rusting is a chemical change.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
No, it is a chemical change (conversion to iron oxide)
Physical.
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.
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.
