Magnesium Lab

Safety:

Materials:

Ring StandBunsen Burner

Crucible

Stirring Rod

Balance

Distilled Water

Tongs

Clay Triangle

Striker

Procedure:

1. Place the ring on the ring stand 7 centimeters above the bunsen burner.
2. Put the clay triangle on the ring.
3. Roll about 25 centimeters of the magnesium ribbon into a loose ball.
4. Measure the mass of the crucible and magnesium.
5. Place the magnesium in the crucible.
6. Turn on the bunsen burner so that the flame is slightly touching the bottom of the crucible.
7. After two minutes, take the magnesium out of the crucible and put it directly into the flame.
8. The magnesium shines a bright light that you cannot look directly into. Use your peripheral vision to place it back into the crucible.
9. After the magnesium burns, measure the mass again.
10. Add distilled water to the crucible.
11. Stir the mixture.
12. See if it conducts energy by putting a type of circuit that has lights on it and connect it to the batteries.
13. The magnesium conducts energy if the light turns on.

Results:

After adding the distilled water, the mass increased about .05 grams. The circuit light turned on, which means the magnesium did conduct electricity. This proves that it is a good conductor and can be used in appliances.

Questions:

1. Magnesium Before: .18g After: .23g
2. Kinetic energy was released because it gave off heat and light.
3. Magnesium reacts with air because it burned and gave off a bright light.
4. MgO. Mg3N2.
5. Nitrogen and Oxygen is a compound because it shows different colors of light.
6. It conducted electricity. It showed that it is ionic because there was one metal and one nonmetal.
7. I think the magnesium could lose mass if it wasn't all burned.
8. Magnesium helps maintain normal muscle and nerve function, a steady heart rhythm, supports a healthy immune system, and keeps bones strong. About 50% of body magnesium is found in bones.
9. Mg(OH)2 is a medicine used for heartburn relief and a sore stomach called Magnesium Hydroxide.
