Is rust an example of a physical change or a chemical change?
It is an example of chemical change which cannot be reversed. In this change, Iron oxidizes under the presence of oxygen and moisture. The reaction is called a reduction-oxidation, or redox, reaction.
Is saltwater a chemical reaction?
Adding salt to water is not a chemical reaction, nor is it a chemical change. When salt dissolves in water, this is an example of a physical change. Although the sodium and chlorine ions separate in the water, no chemical reaction takes place.
What is a non example of chemical changes?
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
