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 tearing cloth a physical or chemical change?
It is PHYSICAL CHANGE because it does not change into another substance and it does not have chemical reaction, it can be sewn back to return to its original form.
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.
Is A glue gun melting glue is an example of a physical change?
Yes, a glue gun melting glue is an example of a physical change because the glue changes from a solid to a liquid without undergoing any chemical reaction.
Example of physical and chemical?
A physical change is melting.A chemical change is combustion.
Is fizzing is an example of physical change?
Fizzing is the result of a chemical change - a chemical reaction with gas releasing.
What is paper burning an example of?
A chemical reaction, and also a reaction in general.
Is snow melting when salt is added a chemical or physical change?
Melting of ice with salt is example of physical change as there is no chemical reaction involved .

Is dissolving a physical or chemical reaction?
a physical reaction for the chemical structure is not changing.

Dissolving salt in water is an example of a physical change. Although the ions of sodium and chlorine separate when the salt dissolves, no chemical reaction takes place.
Is water a chemical reaction or a physical reaction?
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
Is A glue gun melting glue is an example of a physical change?
Yes, a glue gun melting glue is an example of a physical change because the glue changes from a solid to a liquid without undergoing any chemical reaction.
Is fireworks a physical change?
Yes, fireworks involve a chemical reaction where the materials inside the firework combine to produce light, heat, and sound. This chemical reaction is not reversible, so it is considered a chemical change rather than a physical change.
