Aim:
To observe the various mass changes of a magnesium ribbon before combustion and then again after combustion and then compare the results, using different lengths of magnesium ribbons.
Hypothesis:
My hypothesis is that the mass of magnesium after it reacts with oxygen will be greater than the original mass of magnesium before the reaction took place.
Apparatus:
- Crucible
- Lid of the Crucible
- A magnesium ribbon (2cm for our group)
- Sand paper
- Tongs
- Bunsen burner
- Tripod stand
- Clay Triangle
Method:
- Take the magnesium ribbon and clean it with the sand paper
- Measure the weight of the empty crucible with the lid on
- Take a specified length of the magnesium ribbon, that was assigned to your group, and then coil it
- Put the coiled magnesium ribbon in the empty crucible
- Measure the weight of the crucible with the magnesium ribbon inside and with the lid on
- After measuring find the weight of the magnesium
- Put the clay triangle on the tripod stand
- Put the crucible on the tripod stand
- Switch on the Bunsen burner and let the crucible heat
- Keep opening the lid after a few minutes for the oxygen to come in and react with the heating magnesium
- After the magnesium ribbon is heated and when magnesium oxide is formed, measure the weight and compare the weight of magnesium with magnesium oxide.
