2crucible before burning weighs 33.75 oz
3.crucible after burning weighs 33.75 oz
4.solution was conductive.

question and answer:

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.

2. what kind of energy was released by the reaction? What can you conclude about the products of this reaction?

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

you know because there was still some magnesium residue left in the crucible and when we mixed that with water it made the lights light up.


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.

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

nitrogen because when the magnesium was burning it was more yellow than white.


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

yes it did conduct and electric current because it lite up the lights and no we can not determine if they are ionic or not.


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

i think a possible air was that we didn't get the measurements right or that the magnesium didn't get burnt as well as it should have.


8.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?

9. research the use of Mg(OH)2 in everyday products. What is Mg(OH)2 commonly called in over-the-counter drugs?

It is put in water to make milk of magnesia and also relieves heart burn, sore stomach, and some side effects are nausea and cramping.

Safety Concerns--
> refrain from wearing baggy clothing
> wear proper eye protection
> refrain from wearing open toed shoes
> for girls (and some guys) have your hair pulled back
> do not look at the burning magnesium once it ignites, becuase it emits a bright UV light

Materials--
-crucible
-bunsen burner
-tongs
-matches/striker/lighter
-magnesium wiring
-triangle holder

Procedure--
1.) Measure about two 2" strips of magnesium "wiring" and twist them together
2.) Get you bunsen burner lit, and burning well.
3.) Get your crucible sitting in the little triange holder thing.
4.) Let the magnesium heat for two minutes.
5.) If nothing happens after two minutes, you may take the magnesium out with tongs and put it directly into the flame, just be aware that once it ignites you can only look at it with your peripheral vision to get it back into the crucible.

Luke and I, we did all of the first three steps in order. But as we watched another group wait for two minutes and nothing happened we decided to just put our magnesium straight into the flame. The effect was almost immediate, and the magnesium light up like a star. Luke video-taped it for us to use in our respective blogs, and it will be listed below.

Results--
             MASS
             > Empty--21.82g
             > w/ Magnesium--21.95
             > after burn--21.96g
It left a conducive substance behind after it burned. We were able to light up the light bulbs without touching the circuits wiring ends together.

Analyze
1.) TABLE
  Empty Crucible--21.82g
   Crucible w/ Mg before heating--21.95g
   Magnesium ribbon--.13g
   Crucible w/ Mg after burn--21.96g
   Mg products--.01g

2.) It was an exothermic reaction, becuase it gave off heat. That when the metal burnt, it burned off any pockets of oxygen in the magnesium, making it heavier.

3.) Because magnesium can be filled up with electrons fully by nitrogen and oxygen, depending on the amount of magnesium involved. And by depending on the color of the light when it burned.
4.) MgO and Mg2N2

5.) Magnesium and oxygen make up the majority of the remaining product.

6.) Yes it conducted an electric current, this shows that the compounds are ionic.

7.) That you didn't allow for two minutes to pass for oxygen to mix a lot into the crucible.

Real-World Chemistry
 1.)Yes it is listed as a component in a multi-vitamin and mineral tablet.

2.)Mg(OH)2 = Magnesium Hydroxide

SAFETY:
* no baggy clothing/open toed shoes/long hair pulled back
* wear safety glasses
*do not look at the burning magnesium once it ignites, becuase it emits a bright UV light

MATERIALS:
-crucible
-bunsen burner
-tongs
-matches/striker/lighter
-magnesium wiring
-triangle holder

PROCEDURE:
1.) Measure two 2" strips of magnesium and twist them together
2.) Get you bunsen burner lit, with a good flame with the triangle blue
3.) Set your crucible in the triangle holder on top of the burner
4.) Let the magnesium heat for two minutes.
5.) If nothing happens after two minutes, you may take the magnesium out with tongs and put it directly into the flame,do not look at the flame when it lights & turns white. It can burn your eyes because of how bright it is.

Brooke, Jordan & I accidently dropped the first crucible & it broke because we were holding it wrong with the tongs. The second time we did it, nothing happened. We could not get it to light. The third and final time we did it, we did it correct. It lit very fast. I was looking at the bright light for a little while because I forgot that it could burn my eyes but I immediately looked away when I remembered.

RESULTS:
Mass of EMPTY crucible: .8485
With Magnesium .0040
Mass after on fire: 0.8515

Magnesium lab

Materials
Magnesium ribbon
Crucible
Ring stand & ring
Clay triangle
Laybratory bunner
Stirring rod
Crucible tongs
Centigram balance
100-ml beaker distilled water conductivity testers
The object of this lab is to observe the evidence of the chemical reaction. Then to acquire and analyze info that will enable you to decide if the compound has an ionic bond. Lastly to classify if the products is ionic or not ionic
Safety procedure
Wear your hair back in a pony tail
Goggle are to be worn
Wear shoes that cover ur toes
Do not wear baggy cloths.
Procedure
1: gather items
2: place the ring stand and ring on the laboratory burner
3: place clay triangle on ring stand
4: place the crucible on the clay triangle
5: light burner just so the flam is blue
6: place the magnesium strip in the crucible if it doesn't like u will gave to do it by hand. ( don't look into the light$
7: wait for the magnesium to stop burning and then weigh it ( the mass should drop
8: pour 5ml of distilled water into ur beaker and then stir for a minute
9: use the conductivity testers to see if it is conduct.

What kind of energy was released? An ionic energy.
Predict the binary formulas? MgO and MgN

What can you conclude about the product of this reaction? That it mixed with the oxygen and turned white

How do u know that the magnesium metal reacted with certain components in the air? By the color the light was or by what colors the lights should be

The magnesium reacted with both oxygen and nitrogen because of the color. Nitrogen gave of yellow witch u didn't really see and oxygen gave off white. So the reaction happened more with oxygen and magnesium than nitrogen and magnesium.

We had an problem in ours. We did not loss any mass nor did we gain any

Materials: you need a Crucible, a strip of Magnesium, a striker or a lighter, a hair tie, tripod, tongs, stir rod, Bunsen burner, wires, batteries, 5 ml. of distilled water and Christmas lights.

Safety Concerns: hair pulled back , close toed shoes, and safety goggles, no baggie clothes, and don't look directly at the magnesium burning. (shown in picture 4 below)

Procedure: 1. Safety First. Then gather all of your supplies. You start the Bunsen burner put crucible on top in the triangle then let it sit for 2 minutes with the lid on.

2. If not lit after 2 minutes then take the Mg out of crucible and put it in the flame. Once lit on fire use peripheral vision to set it back in the crucible. Make sure you shut off the flame.

3. Wait for it to burn. (wait for crucible to cool and proceed with the lab shown in the picture 1 above.) After the crucible has cooled down put 5 ml. of H2O in the crucible and stick to ends of the wires in the crucible and stir. (shown in the picture 2 above)

Results/Data: Crucible mass: 33.62 oz.

Crucible mass with magnesium: 33.75 oz.

Crucible mass after magnesium burned: 33.75 oz.

(the solution was conductive)

Errors: Errors that could have been made was the scale did not get tared and set back to '0'.

Analysis questions:

1. 13 oz.

2. There was a lot of energy being released from the light that was given off and from the heat.

3. Because the Magnesium left a residue in the crucible from the oxygen and nitrogen in the air.

4. MgO Magnesium Oxide; Mg3N2 Magnesium Nitrate

5. Oxygen makes up most because the residue was white.

6. Yes it did create an electric current and yes it does provide information that it is ionic.

7. An error that could have been made was they didn't tare the scale.

1. Magnesium is found in multi-vitamins and mineral tablets.

2."Milk of Magnesium" its found in something like a tum, for heart burn.

Safety Concerns:
1. Wear safety goggles
2. Hair needs to be pulled back
3. No baggy clothes, especially sweatshirts
4. Closed toe shoes
5. Dont look straight into the burning magnesium,use your peripheral vison
6. Dont touch the hot crucible until it's cooled down completley, it gets very hot

Supplies/Materials for this lab:
1. Crucible
2. Ring stand
3. Triangle holder
4. Bunsen burner
5. Tongs
6. Matches or a lighter
7. 2 strips of wire
8. Electric balance

Procedure:
The very first thing you should do before you get started, is gather all your supplies that i listed above and have them all sitting out. Then you should cut 2 strips of magnesium, about 2 inches each. Then twist them together/intertwine them. Then you should weigh the crucible alone, then with the magnesium strips in it, and write those two down. After all that is done, set the crucible on the clay triangle holder. Once its on that turn the gas on so the flame is about 3 inches high, then light it. Once you light it hurry and set it in the crucible. When it starts to burn do not look directly at the light, look at it at the corner of your eye as the light is very dangerous. Once the magnesium is all burned, you can turn the gas off. Most likely the crucible will be very hot, so let it sit there and cool down for a bit, then grab the tongs and remove it off the triangle holder and place it on the electric balance and take the new mass of it and record it.

My Results:
Mass of EMPTY crucible: .8485
With Magnesium .0040
Mass after on fire: 0.8515

Questions:
1. Already done ^
2. Magnesium Nitrate
3. I know that the magnesium reacts with certain components of the air because of how it reacted and ignited, from the oxygen and nitrogen in the air.
4. Not sure?
5. I think the product that makes most of the light up is the magnesium.
6. I don't think that the compounds are ionic.
7. Possible source of error: Oxygen.
Real World Chemistry questions:
1. Yes
2. Magnesium Oxide is commonly used for heartburn and sore stomach, as far as over the counter drug.

Safety concerns are:
1. Were goggles
2. Be care ful when lighting the magnesium
3. Have a friend help direct your hand holding the magnesium to the crucible (you dont wanna go blind so be shure to get help)
4. Make shure that your flame from the bunsen burner is nit above the crucible or it will either crackor shatter.

Materials:
Crucible
Batteries
Tongs
Stand for crucible
Crucible lid
Magnesium
Masser( electric)


Bunsen burner
Striker for lighting the bunsen burner

Procedure:
First mass the crucible
Then mas the crucible with the magneasium

Magnesium weight is 0.6 grams
Crucible with magnesium is 21.84 grams
After magnesium is burnt in the crucible it. Is massed at 21.89 grams

2.Exothermic energy was released. You can conclude that it lets energy out.

3.The magnesium reacted to the oxygen more than the nitrogen.

4.mgO/magnesium oxide

mg3N2/ magneasium nitrate

5.oxygen

6.the magneasium was conductive and it dose prove that the compound is ionic

7.massed it wrong or electric masser made an error

1. Sometimes found in vitamins

Saftey Concerns


1. Wear goggles while in the lab


2. Tie back loose clothing and hair


3. Do not look directly at the burning magnesium, could blind temporarily of permenatley


4. Do not handle the heated crucible until it has cooled



Supplies


1. Magnesium ribbon
2. Crucible
3. Ring stand
4. Clay triangle
5. Bunsen Burner
6. Stirring rod
7. Crucible tongs
8. Electronic balance
9. Distiller water
10. Conductivity tester
11. FLint striker or some fire making device



Procedure

First gather all the supplies needed to do the lab. Then place the crucible on the electronic balance and calculate the mass of the crucible by its self. After that take a magnesium ribbon and place that on the electronic balance. After calculated place the magnesium ribbon into the crucible and mass both together. Then place the crucible with the magnesium on the clay triangle that is located on the ring stand. Turn on the laboratory burner and light the flame. With the lid on the crucible wait two minutes to see if the magnesium will combust. If the magnesium has not combusted after two minutes take the lid off and wait two minutes to see if the magnesium will combust. If at the end of this and the magnesium has not combusted use the crucible tongs and pick up the magnesium and physically place it within the fire. When the magnesium begins to sparkle be ready to look away. Magnesium burns hot and bright producing a UV light that is harmful to eyes, do not look directly at it. While burning a place the magnesium back in the crucible and turn the burner off. Notice how the crucible glows with the magnesium in it. After the magnesium has stopped burning wait until the the crucible cools, then use the tongs to put the crucible on the electronic balance and calculate the mass of the burned product and crucible.

After calculating the mass, we too the crucible and put 5ml of distilled water into the crucible. We then used a stirring rod to mix the to components into a solution. After stirred we took two D baterries, two alligator clips and a strand of two or three christmas lights. we connected them all together and put the alligator clips into the solution to see if it would hold the current and light the strand of lights.




Data and results


The crucible by itself was massed at 21.82g.

The crucible along with two ribbons of magnesium was massed at 21.95g

The magnesium solution was also conductive

Errors

Errors that could have interfered with the results include:

When lighting the magnesium manually outside of the crucible the oxygen being absorbed did not contribute to the mass after putting it back into the crucible.

Another could also be if you didn't calculate the masses accurately.

Analysis

1. The ribbons of magnesium were massed at .13g and after burned the magnesium product was massed at .01g

2. The energy released during this lab was exoteric energy. The energy gave off a lot of light and a lot of heat. The product after the energy was released was .01g heavier than at the beginning of the lab.

3. After the magnesium burned a white product was left inside the crucible. The white pigment indicated that the magnesium reacted mostly with the oxygen in the air.

4. Since the magnesium reacted more with the oxygen the chemical compound would look like this. MgO. also known as magnesium oxide. If the magnesium would have reacted more with the nitrogen in the air the compound would look like this. Mg3N2. also known as magnesium nitride.

5. After burned we can conclude that oxygen reacted most with the magnesium due to the white pigment displayed.

6. When the magnesium was mixed with distilled water and tested to sdee if the solution was conductive, it came back as positive. The magnesium solution had a conductive quality to it since the solution was ionic.

7. Errors that could have ocurred might include masses the objects inacurrately and also leaving the burning magnesium outside of the crucible for to long which would affect the total mass after burned.

1. Magnesium is found in many multi-vitamins and mineral tablets, and is the fourth most abundant mineral in the human body. Magnesium is needed to make over 300 biochemical reactions within the human body.

2. Magnesium Hydroxide ( Mg(OH)2) is also known as "tums" or antacids in over the counter drugs. This is also known as the "Milk of Magnesium"
