Magnesium Lab

:MATERIALS:

-magnesium ribbon

-crucible
-ring stand and ring
-clay triangle
-laboratory burner
-stirring rod
-crucible tongs
-centigram balance
-100ml beaker
-distiller water
-conductivity tester

: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.
-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.

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.

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

Magnesium Lab

You will need the following items: tripod stand, clay triangle, crucible with lid, electroni scale, Bunsen burner (with access to a source of gas), a striker or a lighter, and a few strips of magnesium. First, find the mass of the empty crucible, record. Then find the mass of the magnesium strips. Then, put the magnesium to the crucible and mass it together. hook up the Bunsen burner to the gas source. Place the tripod stand over the burner and place the clay triangle on the tripod stand. Turn on the gas and light the burner with the striker or lighter. Place lid on the crucible and carefully place the crucible, with the magnesium and lid, onto the clay triangle. Leave the lid on for a few minutes. Remove the lid. The magnesium should light on it's own but if it does not, take a pair of tongs, take out a piece and put in the fire. When it ignites don't look at it due to the danger of uv damage to your eyes. Place the burning piece of magnesium back in the crucible and let it burn down. Turn of the burner. After the crucible cools off find the new mass. It should be less than the original mass of the crucible and magnesium. However when we performed this experiment the mass was the same. Next take a small amount of distilled water and pour it int the crucible. Check the conductivity of the liquid with a conductivity checker. There should be a small electrical charge.

Examples of Gas laws

Charles's law states that when there is constant pressure, temperature and volume are directly related.
An example of this is the pop can lab, when the can went from warm to cold it imploded therefor decreasing the volume of the can.

Boyle's law states that when there is constant temperature, pressure and volume are inversely related to each other. An example of this law is the fog cannon, when the curtain was hit it decreased the volume and increased pressure caused the fog to shoot out.

Gay Lusaac's law states that when there is a constant volume, pressure and temperature are directly related to each other. An example would be the balloon in the flask, when you heated up the water in the flask and then removed the water and covered the top with the balloon the gas inflated the balloon, when you put the balloon into the cold water the pressure on the inside decreased and the balloon was pushed in because the outside pressure was higher.
