A process in which the reactants form products with different chemical compositions is generally a chemical change. It is also often harder to change the products of a chemical reaction back into the reactants, than it is for a physical change. For instance, burning a log would be a chemical change; you don't have wood after you burn the log, you have carbon dioxide, soot, etc., and you can't get the wood back by reversing the process.

Is rust an example of a chemical change?
No, rusting is a chemical reaction in which iron reacts with oxygen in the presence of water to form iron oxide. This process is an example of a chemical change where the substance's chemical composition is altered.
Is rust an example of a chemical change or a physical change?
rusting is oxidation, so it is definitely a chemical change
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
What an example of a physical change?
When it combines with Oxygen. Commonly called Rust.
Is combustion a physical change or a chemical change?
Combustion is basically a chemical reacting with oxygen to become the oxide and water is produced. So when alcohol combusts, for example, it is changed (burned) to carbon dioxide and water. In other words, there is a chemical change.
What is an example of physical rather that a chemical change?
Melting is a physical process.
What is an isoentropic process?
An isoentropic process is a chemical or thermodynamic process in which entropy does not change. An example a reversible adiabatic process is isoentropic.
Chemical change?
The process of changing into entirely new substances.
Is rust an example of a chemical change?
No, rusting is a chemical reaction in which iron reacts with oxygen in the presence of water to form iron oxide. This process is an example of a chemical change where the substance's chemical composition is altered.
Is rust an example of a chemical change or a physical change?
rusting is oxidation, so it is definitely a chemical change
What is an example of a change from electrical energy to chemical energy?
The process of charging a storage battery.
What is an example of an chemical change?
Chemical reactions also known as chemical change occurs when new products are produced due to the reorganization of atoms. The best example for this process is the change from raw food to cooked food.
Is combustion of a fuel that produces carbon dioxide an example of a chemical change?
Yes, combustion of a fuel that produces carbon dioxide is an example of a chemical change. In this process, the chemical composition of the fuel undergoes a change as it reacts with oxygen to form carbon dioxide and release energy.
Is digestion of a candy bar a physical change or chemical change?
Chemical property
Is evaporation a chemical or a physical?
Evaporation is an example of a physical change, as the chemical composition of the substance is not altered in any way.
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 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.
