The process that demonstrates a chemical change is:
**Iron (Fe) reacting to water (H₂O) and oxygen (O) to form iron oxide (Fe₂O₃).**
In this reaction, the iron reacts chemically with water and oxygen, resulting in the formation of a new substance (iron oxide), which is a characteristic of a chemical change.
**Iron (Fe) reacting to water (H₂O) and oxygen (O) to form iron oxide (Fe₂O₃).**
In this reaction, the iron reacts chemically with water and oxygen, resulting in the formation of a new substance (iron oxide), which is a characteristic of a chemical change.
