What are three signs that a chemical change has occured?
chemical change doesn't apper outside easily as it is change in the chemical property of the element or the experiment done,specific methods can only be used to detect the chemical change for the substance under observation.

Is charcoal burn in a grill physical or chemical change?
Its a chemical change because the properties of charcoal are changing when fire makes contact with it. It is realising energy and that is one of the most important signs to know if it is a chemical reaction.
