Question

suppose you find a website that describes rusting of a nail as a change to only the physical properties of iron. would it be accurate

Answer 1

Answer:

The website is inaccurate.

Explanation:

Remember, a chemical change is characterized by many things, but most commonly:

1. A change in color, temperature or state.
2. An irreversible change
3. One or more new substances are formed

Rusting (Iron oxide) is a redox reaction (Oxidation-Reduction Reaction) where  iron molecules come in contact with water and oxygen molecules. The iron molecules lose electrons, becoming oxidized, while oxygen gains electrons, becoming reduced.

Is rust reversable? (No)

Did the colour of the iron on the surface change? (Yes)

Did a new substance form? (Yes, Read above).
