A student measures 10.5 g of mnercury O 1. Heating destroys some mass. oxide into an open test tube and heats it. The heat causes the mercury(II) oxide to decom- pose into mercury and oxygen. After reaction, the student finds the mass of the contents of the tube to be 9.7 g. Which one of the follow- ing describes these observations? 2. The decomposition of mercury(II) oxide does not obey the Law of Conservation of Mass. 3. There must be some pretty big errors associ- ated with the student's measurements. O 4. 0.8 grams of oxygen gas escape from the tube.
