Is a rusting bicycle a physical or chemical change?

Answer 1

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.

Answer 2

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.

Answer 3

A bicycle rusting is a chemical change, a type of chemical change is the ability to rust therefore the bike rusting makes the change a chemical change :D

Answer 4

Rusting is a chemical change as iron combines with oxygen to form a new substance, iron oxide, otherwise known as rust.

Answer 5

Rusting on a bicycle is considered to be a chemical change. Rusting on a bicycle is not considered to be a physical change.

Answer 6

Yes.

If the car is not properly coated with paint, electroplated or galvanized, it will rust when it comes in contact with moisture in the atmosphere.

Answer 7

yes! because once it gets rusted it will never change back

Answer 8

This would be a chemical change as a rusting bike is really going through oxidation, a chemical reaction between oxygen and the materials in the bike.

Answer 9

physical change

Answer 10

a rusty bike is a chemical change
