Final answer:
To design a table for the experiment, record the mass of the empty crucible, the mass of the crucible with magnesium ribbon, and the mass of the crucible with magnesium oxide.
Step-by-step explanation:
To design a table to record the results of the experiment investigating mass changes during chemical reactions, you can create columns for the following data:
- Mass of empty crucible
- Mass of crucible with magnesium ribbon
- Mass of crucible with magnesium oxide
Next, record the mass of the empty crucible, then add the magnesium ribbon and record the new mass. Heat the crucible and magnesium ribbon to allow the reaction to take place and cool it before recording the mass of the crucible with magnesium oxide. This table will help you track the mass changes during the oxidation of magnesium ribbon to form magnesium oxide.
