An example of a chemical change from the options provided is **rust forming on an iron fence**. This process involves a chemical reaction between iron, oxygen, and moisture, resulting in the formation of iron oxide (rust), which is a substance with different properties from the original iron.
On the other hand, distilling a mixture of water and alcohol involves physical separation of components based on differences in boiling points, which is a physical change rather than a chemical change.
