How do you construct a chemistry lab to find the temperature of  the flame of a Bunsen Burner? I have to construct this lab to tell someone else how to be able to find this out for high school. Problem being I have been absent for a period of time and am trying to catch up and missed how to do this. ANy help would be appreciated.

You can get a infrared thermometer. just point it at the flame and it will tell you the temperature. it will also show you the differences when you move to diff rent colors in the flame.. blue being hotter than the yellow.. i bought one on line for 39 dollars from eBay i think

OMG!\ni have the same question!\nmine is:\nA piece of an unknown metal has a mass of 20.0 g and at 100.0 C is placed in a styrofoam cup calorimeter containing 50.7 g of water at 22 C. If the final temp is 27.2 C, calculate the specific heat capacity of the metal. Assume that all the energy lost by the metal is gained by the water.\n\nok, haha fine, not the SAME question, but close enough. But, i'm uber confused. ><

ok, didn't end up making it because it would probably have burnt down my HS football field, but senior year in AP physics after the AP test was over we were told we were going to make rockets.  Then he tells us they're only water pressure rockets.  So my friend and I got pissed because we thought we were going to be able to make real rockets, so we decided we should make ours blow up in mid-air since we were seniors anyway, it was the end of the year, and we were already accepted to college. We wanted to go out with a bang :p  so after discussing it for awhile, we were going to fill up one of the bottles used for structure inside the water-pressure rocket with methane gas right out of the stove, and then put a remote-control car in there with it.  When the rocket was released and at its maximum height, we were going to press the accelerate button on the remote, causing the spark necessary to cause the gas to explode.  Bam, huge ball of flame over the football field.  We didn't do it, we got too scared that burning pieces would come down and land on someone, or burn down the football field, which is where we were testing the rockets.

Hey, i'm doing that for Chem coursework too! AS right?\nanyway, im not entirely sure, but the most important bit you need is a gas syringe to measure the volume of gas.\nOther bits u will need r:\n-conical flask on tripod, with bunsen underneath.\n-A bung with a glass tube in, to put in the conical flask.\n-This tube leads to the gas syringe, via a rubber seal.\n-Remember the CaCO3 goes in the conical flask.\n-Now all you need to do is heat the CaCO3.\n\nYour welcome!

To understand this question, you need to know what kind of product will be produced during a combustion. Generally, for a complete combustion of a hydrocarbon (contains only H and C), the product will be H2O and CO2. Depending on the C and H content in the hydrocarbon, you will produce different amount of H2O and CO2. \n\nOn the other hand, if it is an incomplete combustion (with limited supply of O2), apart from CO2 and H2O, you may also produce C and CO. The relative amount between them varies depending on the amount of O2 that is made available. With very limited amount of O2, more C (soot) will be produced. This leads to the "sooty" flame you are seeing.\n\nIn order to explain why generally alkenes require less O2 to burn compared to alkanes, let's compare ethane (2 C alkane) and ethene (2 C alkene). \n\nEthane has a formula C2H6 while ethene has a formula C2H4. Their corresponding balanced equation for combustion are:\n\nC2H6 + 7/2 O2 → 2 CO2 + 3 H2O\nC2H4 + 3 O2 → 2CO2 + 2 H2O\n\nAs you see, since both compounds have same number of C, they both produce 2 mole of CO2 for every mole of compound. However, since they have different number of H, the number of moles of H2O produced will be different. Since H2O has a fixed formula, in order to produce it, you need to supply O2. That's why the two compounds require different amount of O2.\n\nThe reason that you see a sooty flame is due to the fact that you don't have enough oxygen supply during the burning process. You can easily confirm this by using just a Bunsen burner (but be very carefully!!!). First, turn on your Bunsen burner with the air hole closed. The flame you see at the moment should be a luminous flame. It is golden yellow color. Now, if you carefully put a glass plate (hold with clamp or other device) on top of the flame and slowly move towards the tip of the burner (but don't cover it completely), you should see the plate will get "darker" by the flame. This is the soot produced during the combustion. Now, take away the plate, open the air hole in the burner to the max. You should see a the flame turns to blue. If you put the glass plate (with the soot marks) back to the flame, you can see the flame can slowly "clean up" the plate (if enough O2 is supplied with the flame) and the soot will disappear. The soot is turn back to CO2 due to the excess of O2.

Since we don't know what "this lab" or "this investigation" refers to, we probably can't really help you.  Try asking a classmate or the teacher for help, since they know what "this" refers to.

Your unknown compound might be an impure substance.  The impurities will skew the melting point.  You should find out if the substance is pure or not.  Pure substances (that is, with nothing else mixed with them) will have a narrow ranging in which they melt, for example, pure Naphthalene melts between 83-85 Celsius.

Are you sure the unit is micropascal? I think there is an error in you units, its too small.\n3141.59 micropascal = 0.000000031 atmosphere\n\nPressure in ideal monoatomic gases is directly proportional to temperature, so: \nP1/T1=P2/T2\nT(ºK)=42,000*(177.94+273)/.000000031\n\nCheck the units and resolve it the same way.

I rock on the search engine !\n\nhere you go\n\nhttp://chemistry.about.com/library/weekly/aa020603a.htm\n\nsorry I only see two though\n\nsometimes if you type your question into a search engine instead of asking a question you may get somewhere.\n\nNo wonder your in summer school.

Look up stuff like Arrhenius equations. I don't have my phys chem text book to hand.\n\nFor part two, I think it's D, as I'm fairly certain it's not any of the others.

A down on his luck mathematician interviewed for a job as a fireman.  He was asked the question in his interview, "If there was a paper fire in a dumpster, how would you deal with it?"  The mathematician proceeded to describe how he'd get the fire hose and fill the dumpster with water, thereby extinguishing the fire.\n\nTwo weeks later, the fire company, with the mathematician as a new member, responded to a fire at a warehouse.  Arriving at the warehouse, they found a pallet of paper brochures on fire.  Quickly, the mathematician opened a warehouse door, grabbed a pallet jack, pushed the pallet into a dumpster outside the warehouse door, then grabbed a fire hose and fills the dumpster.\n\nThe fire chief was furious?  "What the heck you were doing?" he asked the mathematician.  The mathematician responded, "I simply re-expressed the problem in terms of a problem with a known solution."

Who cares, all flames are hot.\n\n"The color and temperature of a flame are dependent on the type of fuel involved in the combustion."

id say reactions can occur at any temperature above 0k. so 0.00000000000000000000000000000001K, the reaction would happen but really really really really relaly slowly. but thatz in theory. i have no clue bout pracitcally. i think the lowest temp theyve got to so far is either 4K or 0.6K. so ya.

You've taken the first step in a good scientific inquiry.  You observed a phenomenon and began trying to explain it.  Now you can work toward an answer.  You could see if sugar (glucose?  sucrose?) is a molecule similar to salt for elevating the boiling point of water. (It depresses the freezing point like salt does.)  You could try measuring water just as it boils, and then with the same instrument, measure sugar-water just as it boils, and see if it really is elevated.  You can learn more about the subject by reading.  The melting point of glucose (C6 H12 O6) is 113 degrees Centigrade, higher than the boiling point of water.\n\nThen you can formulate theories as possible explanations.  You've started doing that.  Then you can investigate those.  Here's another.  Perhaps dissolving sugar is an endothermic reaction.  Mix some sugar and water which are both at the same temperature.  Does the temperature of the mixture change?\n\nIt takes a certain amount of energy to raise the temperature of water.  Look up the definition of calorie.  It takes additional energy to convert it from its liquid state to its gaseous state.\n\nIt often takes some discontinuity for a supercooled solution to freeze or form crystals, or for a superheated solution to boil.  The bottom of the pot has such discontinuities, and particularly irregular parts of the pot are where boiling likely starts.  When you add granulated sugar, you are adding lots of discontinuities.  What happens when you add dissolved sugar instead of granulated sugar?\n\nKeep good records, sign and date your notes and get them witnessed periodically.  They could be your first steps toward a very good science fair project or perhaps a bigger discovery and a patent.  Then, tell the world I helped you along.  That would REALLY make my day!

SLap yourself about ten times and take ten deep breathes. Calm down. In chemistry you miss one thing you start to fail. I'm taking Chemistry right now, and its a piece of cake. What you need to so is talk to your teacher and your parents. Come out and say, " I HAVE NO IDEA WHATS GOING ON!!" Tell your teacher to break it down so far that a toddler could understand. You can get it, you just need the confidence. You'll have to spend more time with your teacher. Also look to the smartest person in the class, ask them for help. You'll understand a lot better since they're you're age. I haven't gone too far in chemistry but feel free to ask me questions about electron configuration, and other things at donovangray6@yahoo.com . Other than that, i have nothing. Sorry. But please e-mail me. I live on the east coast. I'll try to help you.
