Magnesium Burning Lab

Materials
1.Crucible
2.Magnesium
3.Scale
4.Bunsen Burner
5.Ring Stand

Safety:
1. Do not look at burning magnesium, bright enough to harm eyes.
2. Wear safety goggles.
3. Use the tongs to hold magnesium.

Procedure:
1. Record the mass of the crucible
2. Take strips of magnesium and weigh them
3. Turn on the bunsen burner below the crucible
4. Make a ball with the magnesium strips and place them in the crucible
5. Put the lid on the crucible and wait for the magnesium to light, if it does not light, then take the lid off and use the tongs to take a strip of magnesium out and light it, then look through corner of eye and place in the crucible.
6. After it is all burned in the crucible, turn off the bunsen burner and then weigh it and subtract the weight of the crucible.
7. After that hook it up to the batteries and the lights to see if it conducts electricity.

Question:
1.Magnesium Before-.17g Magnesium After-.22g Increase-.05g
2.The burning magnesium produced lots of light which means that it was electrical energy.
3.We know it reacts with the air because when it burned it gave off a very bright light.
4.MgO Mg^3N^2
5.The product has to be made up of mostly oxygen because the majority of the light when it was burning was white.
6.The magnesium conducted electricity and it was an ionic bond because a nonmetal and metal were the two elements bonding.
7.If the magnesium was only partially burned and strips of magnesium were left then the mass could have increased.
8.The majority of magnesium in our bodies is found in our bones. Other magnesium is in tissues and organs and it is an ingredient in multi vitamins.
9.Milk of magnesia.

Materials

• Bunsen Burner
• Cruicble
• Ring stand
• Tongs
• Striker
• Scale
• 1g magnesium Ribbon
• various size of batteries
• Distilled water
• light strip
• wire strippers

Procedure

• zero the scale and weigh the crucible
• attach the bunsen burner to the gas nozzle
• Find and weight magnesium ribbon
• place the ribbon in the crucible
• turn the gas on light the bunsen burner
• adjust the heat so the tip barley touches the the bottom of the crucible
• let it heat for 2 1/2 minutes or so
• use the tongs to pull out the ribbon do not look at the ribbon!!!! then place it back in
• wait for the magnesium to burn out
• weigh the crucible then compare it with the beginning weight and the weight of the ribbon
• add distilled water to the magnesium then stir
• take the other ends and hook them to various sizes or batteries to see if a light turns on
• when cleaning out crucible dumb mixture in trash and wipe out with a paper towel

Results

I noticed that the crucible was the same weight after igniting and before igniting the magnesium. a faint red light would come on in the light strip while in the mixture with the 2 batteries.

Errors

I didnt notice any errors.

Analysis

• Mg=.4 Mg after=.4 increase=0
• the energy given off was kinetic energy cause of the the light and the heat given off during the reaction
• due to the bright light given off during the reaction magnesium reacts with air
• Mgo, Mg3N2
• because of the light and energy Mgo and Mg3N2 are mainly made up of nitrogen and oxygen
• its a ionic b0nd cause 1 metal and 1 nonmetal that form together
• if a loss in mass occurred then there was probably left over magnesium in the crucible
• magnesium supports a healthy immune system, strong bones, muscle development, and nerve development
• magnesium is commonly used for heartburn to calm stomachs, often used in the form of magnesium hyrdroxide

Safety

**Before doing anything please make sure that any long sleeves are rolled up, baggy sweatshirts are taken off, and you are always wearing goggles! If you have any questions or concerns please ask a teacher first. DO NOT LOOK AT IGNITED MAGNESIUM

Materials

• Crucible
• Tongs
• Ring Stand
• Clay Triangle
• Bunsen Burner
• Striker
• Scale
• 1g of Magnesium Ribbon
• Distilled Water
• Various sizes of batteries
• Light Strip
• Wire Strippers

Procedure

1. Find crucible and weight it before doing anything using a scale
2. Setup ringstand over bunsen burner and place clay triangle on the stand
3. Attach bunsen burner to gas (do not ignite)
4. Find and weight magnesium ribbon
5. Place ribbon in crucible
6. Turn gas on and light the bunsen burner
7. Adjust heat so the tip of the flame barely touches the bottom of the crucible
8. Let heat for 2-3 minutes
9. If the magnesium doesn't ignite then use the tongs and pull a piece of ribbon out and place it in the flame until it ignites. DO NOT LOOK AT RIBBON place ribbon    back in crucible.
10. Wait for magnesium to burn out
11. Weigh the crucible after it has cooled off and compare with beginning weight plus the weight of the ribbon
12. Add distilled water to magnesium and stir
13. Take a light strip and strip the ends and connect them to clamps and place them in the mixture
14. Take the other ends and hook them to various sizes of batteries and see if a light goes on inside one of the lights
15. When cleaning out crucible dump mixture in TRASH and wipe out carefully with a paper towel.

Results

For my results I noticed that the crucible was the same after igniting the magnesium as it was before if you would add the weight of the crucible and the ribbon. After a while a faint red light came on in the light strip when it was in the mixture with two d batteries.

Errors

If anything went wrong in this lab it would have been when I weighed the magnesium. The scale was zeroed at first but after I took the ribbon off it went to -.3g.

Analysis

1. Mg before = .4         Mg After = .4        Increase = 0
2. The energy given off was Kinetic Energy due to the light and heat that was given off during the reaction
3. Due to the bright light when it burned it seems like Magnesium reacts with air.
4. Mgo; Mg3N2
5. Because of the light and energy, Mgo and Mg3N2 are mostly Nitrogen and Oxygen.
6. It's an ionic bond because it is 1 metal and 1 nonmetal that form together chemically.
7. If a loss of mass occurred than, more than likely, there was probably left over Magnesium in the bottom of the crucible.
8. Magnesium supports strong bones, a healthy immune system, muscle development, and nerve development.
9. Magnesium is commonly used for heartburn relief and to calm sore stomachs. It is often used in the form of Magnesium Hydroxide.

Magnesium Lab

Materials needed:

• Bunsen Burner
• Clay Triangle
• Ring Stand
• Crucible
• Magnesium
• Scale
• Battery
• Cables
• Christmas lights
• Tongs

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Safety:

ALWAYS wear safety goggles to protect your eyes from getting anything harmful into your eyes. Be careful using the magnesium! Use the tongs...they are your friend, they are there to help you. The UV rays the magnesium emits can seriously damage your eyes, so DO NOT LOOK DIRECTLY AT THE MAGNESIUM WHEN LIT!!!!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Procedure:

Have your materials all together, and have it all set up. Use the scale to find the mass of your crucible. Zero the scale, then put down one strip at a time on the scale until it shows a number. Keep the mass of the magnesium you use between .1g-.3g. Roll the magnesium into a very loose ball, and put in the crucible. You need to then put the crucible on the clay triangle that is on the ring stand over the bunsen burner. Have the flame on the bunsen burner barely touching the crucible so the magnesium will ignite. Put the lid on the crucible and wait a couple minutes. if the magnesium doesn't light after a few minutes, take the lid off the crucible and wait a couple more minutes. If you are still having problems with it igniting after that, then using tongs/tweezers, take out one of the strips of magnesium, and put it right in the flame. As soon as you put it directly in the flame, you need to immediately put it back in the crucible. This is where you definitely do not want to look directly at the magnesium. Try to look out of the corner of your eyes if you can! When it is done burning, you will use the tongs, and grab the crucible (don't touch with hands, it is still hot) and mass the crucible with whatever is left of the magnesium inside. After massing the crucible with contents, put distilled water in the crucible with the left over magnesium, and stir. You now get to find out if it will conduct electricity! Put a circuit connected to a little strand of Christmas lights, and connect that to the batteries. If the lights come on, even if it is a low light, you will know your magnesium can conduct electricity. If it does not conduct electricity, however, then you may have done something wrong.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Book Questions:

1) Use the masses in the table to calculate the mass of the magnesium ribbon and the mass of the magnesium product. Record these masses in the table.

Before: .10g

After: .10g

2) What kind of energy was released by the reaction? What can you conclude about the product of this reaction?

This reaction created electric energy. Because the Christmas lights lit up when we used the cables and the batteries, it proves there was electronegativity.

3) How do you know that the magnesium metal reacts with certain components of the air?

Because when it ignited, it had a change of color, and gave off heat.

4) Magnesium reacts with both oxygen and nitrogen from the air at the high temperature of the crucible. Predict the binary formulas for both products. Write the names of these two compounds.

MgO and Mg^5N^2

5)The product formed from magnesium and oxygen is white, and the product formed from magnesium and nitrogen is yellow. From your observations, which compound makes up most of the product?

Oxygen makes up most of the product. We know this because it first burned yellow, only to change to a white color.

6) Did the magnesium compounds and water conduct an electric current? Do the results indicate whether or not the compounds are ionic?

Yes, they conducted an electric current. The compound is ionic.

7)If the magnesium loses mass instead of gaining mass, what do you think was a possible source of the error?

With my group, we didn't have a change in mass, so we probably didn't do it exactly right.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1)The magnesium ion plays an important role in a person's biochemistry. Research the role of this electrolyte in your physical and mental health. Is magnesium listed as a component in a multi-vitamin and mineral tablet?

Approximately 50% or total body magnesium is found in bone. The other half is found inside cells of body tissues and organs. Only 1% of magnesium is found in blood, but levels stay constant. Magnesium(Mg2+) is also an electrolyte supplement that helps with my heart condition, Neurocardiogenic Syncope.

2) Research the use of Mg(OH)2 in every day products. What is Mg(OH)2 commonly called in over-the-counter drugs?

Burning Magnesium

Materials:

• Ring Stand
• Crucible
• Clay Ring
• Bunsen Burner
• Magnesium
• Scale

Safety:

• Wear Safety Goggles so the burning magnesium won't blow into your eyes
• Use tongs to hold on to magnesium
•  DO NOT LOOK AT THE BURNING LIGHT. IT HAS ULTRAVIOLET RAYS THAT COULD PERMANENTLY DAMAGE YOUR EYES.

Procedure:

• First locate all of the materials needed for the lab
• Next, weigh the crucible and write down its weight
• Then grab several strips of magnesium and weigh them.Try to keep mass of total magnesium over .1g and less than .3g
• Now you're going to wad up the magnesium and put it in the crucible.
• The next thing is to turn on the bunsen burner so that the flame is barely touching the bottom of the crucible.
• Now you have to wait for the magnesium to catch fire. If after two minutes or so it hasn't caught fire, take one strip of magnesium out and put it right in the flame. Without looking at the now burning spark of death, try to use your peripheral vision to put it back into the crucible.
• Finally once it has finished burning, you will mass the crucible with the contents inside.
• The last thing is to add distilled water to the crucible and stir and see if it conducts electricity by putting a circuit with lights on it and connect it to the batteries.
• If the light turns on then you know the magnesium conducts electricity.

Results:
We concluded that the mass of the magnesium after it had burned, increased by .05g. We also found out that after we added the distilled water to the crucible and mixed it, the substance containing magnesium did conduct electricity through the circuit and the light turned on. This means that magnesium itself is a good conductor of electricity and can be used in many appliances.

Questions:

1. Magnesium Before-.17g                   Magnesium After-.22g                    Increase-.05g
2. Kinetic Energy was released by the product because it gave off heat and light
3. We know the magnesium reacts with the air because it started to burn pure magnesium and gave off a bright light
4. MgO; Mg3N2
5. The compound that makes up most of the products of MgO and Mg3N2 is mostly nitrogen and oxygen because it gives off different colors of light.
6. The magnesium did conduct electricity. The results did tell that the compounds were ionic because there was one metal and one nonmetal and it conducted electricity.
7. I think that if the magnesium would've lost mass is if not all the magnesium burned and left some ribbons in the bottom along with some burned pieces.
8. Magnesium helps maintain normal muscle and nerve function, helps maintain a steady heart rhythm, supports a healthy immune stystem, and keeps bones strong. About 50% of total body magnesium is found in the bones.
9. Mg(OH)2 is used as a medicine for relief of heartburn and sore stomach. It is commonly called an over-the-counter drug called magnesium hydroxide.

Magnesium Lab

Materials-

• Bunsen burner
• Crucible
• Ring stand
• Clay triangle
• Magnesium ribbons
• Battery and cables
• Short string of Christmas lights

Safety Precautions

• Always have your goggles on.
• When the magnesium has ignited DO NOT look directly at the magnesium. It gives off damaging UV rays that can damage you eyes.
• Use tongs when igniting magnesium or moving a hot crucible.
  

Procedure

1. Once you have all of your materials gathered fin the mass of your crucible and record it on your data table.
2. Take your magnesium and place one strip at a time onto a scale until it registers a number. Record the number.
3. Crumble the magnesium into a loose ball then place it in the crucible and then place the lid on top of the crucible.
4. Put the crucible on the clay triangle and place it on the ring stand that is over the bunsen burner.
5. Turn on the bunsen burner so that it is heating the crucible with the magnesium.
6. Let it sit with the lid on for a few minutes.
7. If the magnesium does not ignite take the lid off and wait for a few minutes.
8. If it still has not ignited take out a strip of magnesium, hold it in the flame for a few moments until it ignites. Use your peripheral vision to observe the magnesium, DON'T look directly at it. Then place the strip back into the crucible.
   
9. Weigh the remaining magnesium ( weigh the magnesium and the crucible and subtract the weight of the crucible) and record it in your data table.
10. Then fill the crucible with water and connect the battery to the cables and the Christmas lights. If the Christmas lights give off a glow, you know that magnesium conducts electricity.

Question

1. Before= .1g of magnesium After= .4g Difference= gained .3g
   
2. Thermal energy was given off when the magnesium ignited and so was light. This means that a chemical reaction occurred, so we can assume that a new product was formed.
3. We know that the magnesium reacted with the air because it increased by .3g so it had to bond with other elements in the air because that made the mass increase.
4. Mg3 N2 Mg O
5. Magnesium Oxide, from looking at the ashes the majority of our product was white.
6. The magnesium compound did conduct an electric current. We know that it is ionic because It is between a metal (magnesium) and a nonmetal (oxygen/nitrogen). Also, this is just a guess, but ionic compounds make positive and negative ions, would that have anything to do with electricity flowing from one charge to the next?
7. An error could be that the person doing the experiment could have not massed the crucible or the magnesium correctly at the beginning or the end of the lab.
8. Yes
9. Milk of Magnesia

Burning Magnesium Morgan Vanderpool

The first picture is a picture of just crucible without the magnesium inside. The mass is 23.02. The second picture is a picture of the set up after the magnesium is added to the crucible and the Bunsen burner is underneath the tripod heating the crucible. The third picture is a picture of the the magnesium added to the crucible its mass is 23.19. The fourth picture is a picture of some materials you will need during the burning of the magnesium. The fifth picture is a picture of tongs that you will use in case the magnesium does not lit fire. You will use the tongs to lift the lid off of the crucible and pick up the magnesium to put the magnesium under the fire to light it. If it lights then look out of the corner of your eye to put the magnesium back into the crucible because the light is very bright and could hurt your eyes. Speaking of your eyes showing you in the second to the last picture make sure to have your safety eye glasses on at all times. Also in the picture is a hair tie so if you have long hair you need to put it up. In the last picture is of the magnesium all burned up in the crucible weighing 23.18
Questions:

1. Mass of magnesium before was 23.02g and after the magnesium was burned its mass was 23.19g. The difference between before and after was .17g.


2. The Kinetic energy was released by the product because it gave off heat and light.
3. The Magnesium reacts with certain air components because when the magnesium was lit fire the oxygen was lit also making the magnesium react with the little amount of oxygen.
4. Magnesium Oxide , Magnesium3 Nitride2.
5. After the magnesium was completely burned all that was left was white leaving the product formed from oxygen and magnesium.
6. Yes, there was an electric current that conducted with the magnesium compounds. No, nothing showed that the compounds were ion
7. Its the incorrect measurement, or you didn't let the magnesium completely melt.
8. Magnesium is the fourth most abundant mineral in the body and makes up 50% of the bodies bones and cells. Magnesium is very important for your physical and mental health and can be listed in many different types of vitamins and minerals.
9. Magnesium hydroxide or milk of magnesium.

1. Find all of your equiptment and make sure it it clean and useable.
2. Mass your magnesium strips in the crucible until the number of the mass goes up from the empty crucible.
3. Roll the strips you massed into a ball and place it in your crucible,which should be on your clay triangle on a ring stand over a bunsen burner.
4. Turn on your bunsen burner and light it, make sure your flame isn't too high.
5. Let your magnesium sit in your crucible with the lid on for a few minutes. If it doesn't light take the lid off and let it sit. If it still doesn't light you have to pick up your magnesium with tongs and manually light it by puting it in the fire. As soon as it's lit carefully and quickly put it back in the crucible and wait until its done burning.
6. Mass your crucible again and record this mass.
7. Repeat this process from step two
8. Now mix in a little distilled water into the crucible.
9. Connect the cables to the battery and lights. See how the lights light up if its set up right?
10. Now take the cables and out them in the magnesium water. If done right the lights should flicker
11. Now carefully clean up your stations

Book Questions:

1. .17 g to .22 g
2. This lab produced thermal energy because it lit up when on fire.
3. We know because it flickered and didn't really light until lit in the fire.
4. MgO and Mg5N2
5. Oxygen, because when it was done burning it had a more white product
6. Yes, and bothe combinations were metal + non-metal
7. if the producy masses less then maybe you massed wrong

Burning magnessium lab

In this lab we learned how to make magnessium burn. First we had to put goggoles on. Next we had to get all the materials put together.

We then set up the tripod and put a glass beaker on it and then we put the burning magnesium and didnt look at it and put it in the beaker.

Magnesium Lab

Safety: you will need to wear goggles make sure long hair is tied back and when the Magnesium lights make sure not to look directly at it.
Materials needed: you need a ring stand, one gram of magnesium, a Bunsen burner, and some batteries and wire.
Procedure the first thing you need to do is find a crucible and weight it using a scale Setup a ring stand over a Bunsen burner and place clay triangle on the stand and Attach the Bunsen burner to gas Do Not turn the Gas on yet. Find and weight magnesium ribbon Place ribbon in crucible Turn gas on and light the Bunsen burner Adjust heat so the tip of the flame barely touches the bottom of the crucible you should have a blue flame then let it heat for 2-3 minutes. Wait for magnesium to burn out Weigh the crucible after it has cooled off and compare with beginning weight plus the weight of the ribbon mix the water and magnesium and stir Take a light strip and strip the ends and connect them to clamps and place them in the mixture Take the other ends and hook them to batteries and see if a light goes on inside one of the lights When cleaning out crucible dump mixture in TRASH and wipe out carefully with a paper towel.
Results For my results I noticed that the crucible was the same after igniting the magnesium as it was before if you would add the weight of the crucible and the ribbon.

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.
