:MATERIALS:
-ring stand and ring
-clay triangle
-laboratory burner
-stirring rod
-crucible tongs
-centigram balance
-100ml beaker
-distiller water
-conductivity tester
-Wait until the materials that were heated have cooled before handling them
-Tie hair back
-Avoid baggy clothing and Roll up sleeves if necessary
1. On the ringstand place the ring approx. 7 centimeters above the bunsen burner.
2. Take the clay triangle and place it on the ring.
4. Measure the mass of the crucible and the magnesium, and write it down.
5. Put the magnesium inside the crucible.
6. Now you need to turn on your bunsen burner and make it so that the flame is slightly touching the bottom of the crucible.
7. Now you are waiting for the magnesium in the crucible to catch on fire. After two minutes, and nothing has happened, take the magnesium out of the crucible and put it directly in the flame. The magnesium will shine an extremely bright light which can hurt your eyes, so you must use peripheral vision to place it back into the crucible.
8. When the magnesium has finished burning, you need to mass the crucible and its items inside.
9. Now you must use distilled water and add it to the crucible.
10. Stir the mixture and see if it will conduct electricity from it by putting a type of circuit that has lights on it , and then connect it to the batteries.
11. If it does conduct any electricity the lights on the circuit will turn on, and you now know that the magnesium can conduct electricity.
:RESULTS:
I figured out that the magnesium went up about.06 grams. I also discovered that when i put the distilled water into the crucible and then stirred it up, that it has the ability to conduct electricity. We now know that the magnesium in the crucible can be used for many other things, since it is considered to be a good conducter for electricity to run through.
:QUESTIONS:
1. Magnesium before the heat-.11grams Magnesium After the heating-.17grams. There was an increase of .o6 grams
2. The type of energy that came from it was kinetic because it showed light and heat.
3. When the magnesium began to get burned, and it showed a very bright light, we can conclude that it did mix with air.
5. Nitrogen and oxygen is a compound in this lab because it was able to show different colors of light.
6. The compounds were considered ionic from the results i got. It conducted electricity by having one that was purely nonmetal and the other one being metal.
7. I believe that there could be things left behind in the crucible, or maybe some pieces that had become burned and fell off, that would have caused the magnesium to lose some of its mass.
8. Magnesium- Healthy immune system, steady heart beat, nerves, keeps muscles normal. Magnesium is mainly in our bones.
9. Magnesium hydroxide is what Mg(OH)2 is called if it is a over the counter type of drug.

:SAFETY PRECAUTIONS:
-Wear safety glasses
-Dont look at the burning magnesium. The intensity from its light will damage your eyes if you look at it directly.-Wear safety glasses
-Wait until the materials that were heated have cooled before handling them
-Tie hair back
-Avoid baggy clothing and Roll up sleeves if necessary
:PROCEDURE:
1. On the ringstand place the ring approx. 7 centimeters above the bunsen burner.
2. Take the clay triangle and place it on the ring.
3. Take about 25 cm of the magnesium ribbon and roll it into a loose ball.
4. Measure the mass of the crucible and the magnesium, and write it down.
5. Put the magnesium inside the crucible.
6. Now you need to turn on your bunsen burner and make it so that the flame is slightly touching the bottom of the crucible.
