Magnesium Lab

You will need:
-crucible
-clay triangle
-bunsen burner
-scale
-magnesium
-lighter

Procedure:
1. Find the mass of an empty crucible
2. Find the mass of the magnesium strips
3. Mass the two together
4. Put crucible w/ magnesium in it on the clay triangle over the flame. Carefully put lid on top of crucible.
5. Magnesium should light by itself but if not then use a lighter. Once it is lit DO NOT look directly at it. It can damage your eyes severely.
6. Let the magnesium burn down until its no longer on fire then find the mass. *Mass should be less then it was before it was lit* In the experiment that was conducted the magnesium didn't change in weight.
7. After weighing the ashes pour distilled water into the crucible. Then take a wire contraption and dip it into the crucible. The christmas lights lit up so the substance could conduct electricity. 

Questions:
1. Before .10g and after .10g

2. Electric energy was created and since the christmas lights lit up there was electronegativity.

3. Change of color, heat, & smell

4. MgO & Mg^5N^2

5. The compound is made up of Oxygen & . We can tell because it burned yellow at first and then changed to burning a white color.

6. The compound is ionic. It has a metal & a non-metal.

7. The weight didn't change so we could have spilled some magnesium or just not burned it all the way.

8. Magnesium is ranked #4 on the most abundant elements list. It is good for you and is found in most multi-vitamins.

9. Milk of Magnesia
