no rusting iron is not a physical change it is a chemical change
Yes, it is, because the chemical composition of the outside changes due to oxydation.
Ah, what a lovely question. When a bicycle rusts, it's actually a chemical change taking place. The metal is reacting with oxygen and moisture in the air, creating a new substance called iron oxide. It's all part of nature's way of transforming things, just like how we transform a blank canvas into a beautiful painting.
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
Anything that happens to it but can be changed back to it's original form such as melting.(not rusting)
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.
No. Rusting is a chemical change.
no it is a chemical change
it 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, it is a chemical change (conversion to iron oxide)
A car Rusting is a chemicall change as a the iron in the car is converted into a different substance: iron oxide.
Iron rusting is a chemical change.
chemical
Physical.
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.
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.
No. Rusting is a chemical change because the chemical composition is changed from iron to iron oxide. The iron reacts with oxygen in the atmosphere, forming iron oxide. Fe + O2 --> Fe2O3
