Iron (Fe) is a chemical element, water is a chemical compound (H2O).
Chemical reaction from water
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
Chemical change, oxygen binds with iron.
Adding water (which is not a reactant) is a physical process.
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.
physical or chemical
physical or chemical
Iron is a chemical element, not a "change" !
Iron is a chemical element, not a "change".
Corrosion is a chemical process.
actually i cannot answer this question because i have no idea for this question....thank you(2x)
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.
