Because molecules have other chemical and physical properties than the containing atoms !
Reactivity is a chemical property.
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
If something reacts with oxygen that is a description of a chemical property.
Chemical
To know if something is a chemical or physical property, you need to know if it is made out of OTHER things. For example, a diamond would be a physical property because it is not made out of other things. The sugar molecule, on the other hand, would be a chemical property because it is made out of other things; carbon, hydrogen, and oxygen. So, is zinc a chemical or physical property?
Yes. oxidation is chemical property. It includes addition of oxygen or removal of hydrogen
No. The ability to react with oxygen is a chemical property because new products with unique properties result.
This is a chemical change.
Chemical
Reacting with oxygen to form an oxide is a chemical property.
The Answer is simply that Corrosion is a Chemical property because it uses oxygen. !
It is a chemical property because water mixing with oxygen forms rust. Rust is a chemical property
