4. A sealed glass tube contains 2.25 g of copper and 3.32 g of sul- fur. The mass of the tube and its contents is 18.48 g. Upon
heating, a reaction forms copper(II) sulfide (Cus). All of the
copper reacts, but only 1.14 g of sulfur reacts. Predict what the
mass of the tube and its contents will be after the reaction is
completed. Explain your reasoning.
