15. Magnesium metal burns vigorously in oxygen to
produce the compound magnesium oxide. Use
the law of conservation of mass to identify the
masses labeled (a), (b), and (c) in the table.
16. Use the data in the completed table to construct
a graph with mass of magnesium on the x-axis
and mass of magnesium oxide on the y-axis.
