rusting of iron
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
melting any metal is physical. rusting iron is chemical
Yes. Iron rusting is a chemical change. Rust is no longer iron, but is iron oxide, therefore a chemical reaction has occurred.
Iron rusting is a chemical change.
The rusting of Iron is a chemical change as Iron reacts with Oxygen to form Iron Oxide [Rust]
Rusting iron is the chemical change.
Rusting is a chemical change. it forms one of the iron oxides depending the conditions. Melting is simply changing the form of the metal and of course it reverts to the solid state after the heat source is removed.
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
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.
Because the rusting of iron is based on a chemical change, a reaction of oxydation.
melting any metal is physical. rusting iron is chemical
Rusting of iron is chemical. It is the combination of oxygen with the iron, creating a different chemical: rust or iron oxide.
no it is a chemical change
it is a chemical change
Yes. Iron rusting is a chemical change. Rust is no longer iron, but is iron oxide, therefore a chemical reaction has occurred.
The process of iron rusting is a chemical change.
Examples of chemical changes: * Burning of paper * Rusting of iron Examples of physical reactions: * Melting of ice * Melting of wax
