Your trip to the lab this time should have been explosive - your group was supposed to produce hydrogen gas and then ignite it. Now that you have had this experience, use your results to answer the following questions.
1. Name 2 hazards of this particular lab and the safety precautions used.
2. What was the gas produced in the lab?
3. Why should you have heard a "bark" when the gas was exposed to the flame?
4. What was the substance that was removed by the sandpaper?
5. Name another metal that could probably have been used to produce similar reactions.

1 acid and fire
2 hydrogen
3 because its explodes
4 magnesium
5 aliminum
there was an acid and fire hazards in the lab. hydrogen gas was produced. because the gas exploded!!! magnesium oxide was removed by the sandpaper. and calcium couldve done similar stuff.

1. THE TWO THINGS THAT YOU HAVE TO WORRY ABOUT IS THE FIRE AND THE ACID
2. THE GAS THAT WAS PRODUCED WAS HYDROGEN
3. BECAUSE IT EXPLODES
4.MEAGNESIUME
5.ALUMINUM
1.acid and fire
2.Hydrogen gas
3.because the fire ignited the hydrogen gas.
4.magnesium
5.sodium

1. Two Hazards are dealing with HCL that can harm a person coming into contact with it. Another hazard in the lab was the hydrogen gas created by the chemical reaction, hydrogen being highly flammable.
2. THe gas produced in the lab was hydrogen gas.
3.You should have heard a bark when the gas is exposed to the flame because the gas is hydrogen and it is extremely flamable. The bark was the sound of the hydrogen and fire exlpoding.
4.The substance removed by the sandpaper was magnesium oxide
5.Beryllium is another metal that could have been used in the lab

1)Gas and liquid could be dagerous and thats why we wore goggles, gloves, and an apron.
2)the gas produced was Hydrogen.
3)Made a noise which was an explosion between the magnesium and Hydrocloric acid.
4)The substance removed by the sandpaper was magnesium oxide.
5)Beryllium is another metal that could have been used to produce similar results.
1. Name 2 hazards of this particular lab and the safety precautions used.
*the two hazards would be the acid and the fire...we kept water running during the lab, kept all objects away from the fire.
2. What was the gas produced in the lab?
*hydogen
3. Why should you have heard a "bark" when the gas was exposed to the flame?
*because the gas exploded
4. What was the substance that was removed by the sandpaper?
*lye
5. Name another metal that could probably have been used to produce similar reactions.
*any metal in the same group
that was alicia who posted the last comment

1. The gas and chemical liquid we used could have been dangerous, that is why we wore gloves, goggels, and aprons.
2. The gas that was produced was hydrogen.
3. The bark was the sound of hydrogen and fire exploding.
4. The substance removed by the sandpaper was magnesium oxcide.
5. Another metal that could have been used to produce a similar reaction is Berylium.
1. Before we used the sand paper on the metal it was black and dusty looking, after we used it was shiny and clean. What we removed was magnesium oxide.
2. When the ribbon was placed in the acid it disappered and boiled away and the test tube was hot to the touch.
3. The splint made a weird noise and then it was almost like the smoke melted away.
4. The gas that could ignite explosively was hydrogen because the it was lighter than the air that we breath.

1. Name 2 hazards of this particular lab and the safety precautions used.
We were using an acid which could burn you, so you need to wear gloves. We also used a bunsen burner, which could of burned you so you had to be careful to keep you hair and body from getting burnt.
2. What was the gas produced in the lab?
hydrogen
3. Why should you have heard a "bark" when the gas was exposed to the flame?
the hydrogen exploded
4. What was the substance that was removed by the sandpaper?
magnesium oxide
5. Name another metal that could probably have been used to produce similar reactions.
any metal in the same group.
AMANDA BEARD!!!!!
4. What was the substance that was removed by the sandpaper?
magnesium-oxide
alicia sustaita
1: you are working with an explosive gas, and acid. we wore latex gloves, goggles, and aprons.
2: hydrogen
3: because the gas exploded
4: magnesiumoxide
5:beryillium
by the way this is dustin and you look very gorgeous in your green shirt today, it really brings out your eyes. well i guess i should stop babeling about your beauty, i love you.
1.the fire part and the-the apron
the acid-the goggles
2.hydrogen
3.cause the fire and the magnesium have a chemical reation
4.oxide
5. calcium
Ryan Clark
wtym
1.fire..lab coat
2.hydrochloric acid..gloves
magnesium
because the gas was being mixed with fire which caused a chemical reaction.
oxide
strontium
~Stephanie Luna
1. the two hazards we used in the experiment were fire and acid. we prevented an accident by wearing an apron and goggles.
2. hydrogen
3. because the fire and the magnesium had a chemical reaction.
4. oxide
5. radium
Love Always, Weston Popham
1) The fire, (lab coat), and acid, (gloves).
2) Magnesium Cloride.
3) The gas was being mixed with fire which caused a chemical reaction, which cause a whisling noise
4) Oxide
5) Calcium
-Lacey Voss<3
1.fire and the acid. goggles and gloves
2.hydrogen
3.because the hydrogen is reactive.
4.oxide
5.calcium
Nicholas farias
1. It was a gas and flame caution: so we needed to use gloves and an apren.
2. Hydrogen
3. the 2 gases combined
4. Carbon
5. Calcium

i just responded and forgot to put my name

Ryan Lee's answers:
prepare to be amazed......
1. The hydrochloric acid could of spilt all over my clothes. sooo i wore an apron.
When the reaction happened i could of been burnt. sooo i wore gloves.
2. Hydrogen
3. Cuz the hydrogen should have reacted with the oxygen that was being burnt by the flame.
4. carbon
5. Radium
1. gas and flames: use goggles and an apron.
2. hydrogen
3. the gas was in the same test tube as the flames and they were exposed to each other
4. carbon
5. radium (calcium)
Christina Nunez
1. Ingiting the hydrogen could have been very dangerous if not done properly and you would have had to have been in a very controlled environment. The boiling of the magnesium could have been very disastrous had it not been good if the test tube had spilled.
2. Hydrogen
3. When the Hydrogen ignited these gases released energy that caused the barking sound in question.
4. Oxide
5. Calcium

1. 1: Someone could have been burned by the bunsen burner. 2: The substance you were working with could have touched your skin and contaminated it.
2.hydrogen
3. You should have heard a "bark" because the hydrochloric acid reacted with hydrogen, causing a loud noise
4. magnesium oxide
5.Another substance that could have triggered the same reaction as hydrocloric acid is, sodium chloride
1. Acid couldve been spilled on your skin. You couldve caught long sleeves on fire.
2. Hydrogen
3. Because the fire reacted with the gas let off by the hydrocloric acid and the magnesium.
4. Magnesium Oxide
5. sodium
#1: One hazard is to get acid on your skin, which can be prevented by wearing googles, an apron, gloves, and closed toed shoes. Another hazard is to get burned, which can also be prevented by wearing all those things and to follow the instructions and not get too close the the fire. ( Also make sure to put long hair into a ponytail.)
#2: Hydrogen
#3: When the hydrogen gas was exposed to the flame, it produced an explosion, which is what caused it to make a "bark".
#4: Magnesium oxide
#5: Beryillium
-Leah Taylor-
Bobby was getting X-rays so please don't give him a zero.
This is Tyler...
1. There was the flame from the bunsan burner that u had to have your clothes pulled pack from it and then there was the acid that we protected ourselves from with the apron.
2.hydrogen
3.They gas trying to escape the tube covered by the cardboard was explosive and when it connected with the flame....BOOM...
4.Magnesium Oxide
5.Barium
1.
A)if i wouldn't had put my hair back, then my hair could had caught on fire.
B)if i wouldn't had worn my gloves then the hydrocloric acid could had burnt my hands.
2.hydrogen
3.because hydrogen reacts with a flame and when it was exposed to a flame it exploded and made a noise. (as Ms. Hutson calls it, a BARK)
4.Magnesium Oxide
5.Barium.
any of the Alkaline Earth Metals would be ok.
the one above megans is chelsei's!
i used barium on # 5!!!!!
love chelsei
1) You could get hydrochloric acid on your skin, it was prevented by us wearing gloves, aprons, and goggles.
You could burn yourself on the bunsen burner it was prevented by wearing your hair back and pushing your sleeves back.
2) Hydrogen
3) Hydrogen gas reacts with the flame and it makes a sound, it is a small explosion.
4) Magnesium oxide
5) Calcium or any alkaline earth metal.
