8. A tried-and-true introductory chemistry experiment involves heating finely divided copper metal with sulfur to determine the proportions in which the elements react to form copper (II) sulfide. The experiment works well, because any excess sulfur beyond that required to react with the copper may be simply boiled away from the reaction container.
