Question

For each of the experiments described below, design a table to record the results.

Experiment 1: Simon is investigating mass changes during chemical reactions. He investigates the change in mass when magnesium ribbon is oxidised to form magnesium oxide:

magnesium + oxygen magnesium oxide

He records the mass of an empty crucible. He places a 10 cm strip of magnesium ribbon in the crucible and records the new mass of the crucible. He heats the crucible strongly until all the magnesium ribbon has reacted to form magnesium oxide. He allows the crucible to cool before recording the mass of the crucible and magnesium oxide.

Answer 1

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:

1. Mass of empty crucible
2. Mass of crucible with magnesium ribbon
3. 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.
