NO!!!
It is a slow reaction (chemical change). Iron metal is reacting with oxygen to form iron oxide.
Yes, it is, because the chemical composition of the outside changes due to oxydation.
It's not the rusty bike it's the rusting of the bike. rust forms in a process called oxidation, or when iron comes in contact with oxygen. Also one reason you can tell it's a chemical change is when you can't reverse the process. Or when it involves changing the chemical compound.
Iron to rust is a chemical change . Iron metal is being oxidised by oxygen to form iron oxide (rust)
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.
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
it is a chemical change
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
