What Are The 4 Bunsen Burner Flames?
The four(4) flame types of Bunsen burner is depending on flow through the throat holes (holes on the side of the Bunsen burner -- not to be confused with the needle valve for gas flow adjustment). 1) air hole closed (Safety flame used for when not in use or lighting). 2) air hole slightly open. 3) air hole half open. 4) air hole almost fully open (this is the roaring blue flame).
How do you be safe using a Bunsen burner?
how to be safe using a Bunsen Burner:1. never leave the flame unattended... especially when on the blue flame.2. always wear safety glasses.3. don't heat up anything metal because they will get very hot.4. don't let young children near the Bunsen burner when it's on.5. always have someone watch it.6. turn the gas off immediately when the flame goes out.
Safety proceedures using the Bunsen burner?
Step one: Place the Bunsen burner on a heat proof mat Step two: Check that the rubber tubing is connected properly to the Bunsen burner and the gas tap. step 3: ensure that the air hole is closed Step 4: Light the math Step 5: Open the gas tap Step 6: Hold the burning math over the barrel. Make sure your hand is not in the passage of the flame.
How do you use a Bunsen burner safely?
Turning on the burner safely:1. Turn the gas on at the source of the gas line. This can typically be found where the hose fits over the gas line that sticks out from the wall. You will want to turn it on until you can hear the gas flowing smoothly through the hose.2. Turn on the burner slowly. Once you hear the gas, you can light the Bunsen burner. Keep your fingers as far away from the flame as possible. Depending upon the flint you are using, be it a match or a flint gun, you need to light it on the side of the Bunsen burner so that the flame reaches around the flame and away from you.3. Once the flame is lit, you can adjust the height of the flame to what you will need for your experiment. If you are heating something, you will need to adjust the height of the holding tray to the flame. Do not try to adjust the flame to the height of the holding tray. Flames can and will get out of control if you are not meticulous. It could also wrap around the glass container of the substance and burn it to the glass. Every step counts.4. After the experiment is done and all the data is completed, you will need to turn off the Bunsen burner. To do this, make certain whatever you are heating is off the holding tray is removed. These chemicals can get very dangerous when heated, so be cautious. Remember to use tongs to remove the glass container and put it far enough away from the burner to be safe.5. Once the glass container is removed, turn off the gas at the Bunsen burner's base and at the wall. Once the gas is off, the flame should automatically be extinguished. If it is not, you may have a gas leak. Make certain the gas is completely off on both sides. If it is off and the flame has not gone out, alert your professor immediately.jejeje...-sLuRp3e-. ^_^V
Describe a sinmple experiment you could do to compare conduction in three different metals?
1 Light the Bunsen burner.2Place a lump of Vaseline and a drawing pin on the aluminum stick.3 Place the stick about 3 inches above the flame and start the stopwatch.4 When the drawing pin falls off, stop the stopwatch and record the time.5 Repeat this for the other 3 metal sticks.6 Compare your results and explain in your report why the drawing pin fell off at different speeds.

Is hydrogen in a Bunsen burner?
A Bunsen burner, named after Robert Bunsen, is a common piece of laboratory equipment that produces a single open gas flame, which is used for heating, sterilization, and combustion.[1][2][3][4][5] The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas, such as propane, butane, or a mixture of both.
What is full name of Robert Bunsen?
Robert Bunsen (1811-1899) was a German chemist, discoverer of caesium and rubidium (with Gustav Kirchhoff), is one of the inventors of the Bunsen burner (with Peter Desaga), published many contributions in other chapters of chemistry.

Did Robert Bunsen have any brothers or sisters?
he had 4 brothers but i dont kno their names.
Why is the blue flame the hottest in science?
because you have the vents open on the bunsen burner the flame is getting more oxygen, making it hotter. Different flame types of Bunsen burner depending on flow through the throat holes (holes on the side of the Bunsen burner -- not to be confused with the needle valve for gas flow adjustment). 1) air hole closed (Safety flame used for when not in use or lighting). 2) air hole slightly open. 3) air hole half open. 4) air hole almost fully open (this is the roaring blue flame).
How could you use a piece of iron wire to find the hottest part of a Bunsen burner?
by having 4 iron wires and placing each one of them in different parts of the flame observe the wire then record results not what wire is placed at what part of the bunsen then see which one is the most red (the more red the more hot the area of the flame you have out it on for it to be a fair test you should have the bunsen on a yellow/orange flame and hover the wire with tongs at the different areas do not change to a blue flame for a different wire,this was out of common sense but i dont know if my theory is correct

How would you get pure water from salty water?
You will need: 2 beakers(1 named A and 1 named B) Salty water A stand A Bunsen burner A CLEAN aluminum tray 1.Put the salty water in beaker A. 2.Put the stand and the Bunsen burner under it. 3.Put beaker B and shape next to it. 4.Hold the clean aluminum tray above it diagonally. 5.Turn the Bunsen burner on. 6.Wait for the salty water to evaporate and form water droplets which will fall into the beaker B. And you will get pure water unless the aluminum tray is dirty. -------- - distillation - ion exchange - reverse osmosis etc.
What are 4 facts about the Bunsen Burner?
The Bunsen burner is such a familiar fixture of chemistry labs that its reputation reaches students even before they enter the classroom. As an icon of science, it permeates popular culture. But where did the Bunsen burner come from? Who invented it? You might hope to chuckle at the absurdly obvious: "why, Bunsen, of course!" But a brief foray into history may be warranted before placing too significant a wager on the "obvious."Robert Bunsen, whose name we associate with the burner, was a 19th-century German chemist of some renown. He worked on explosive organic arsenic compounds--leading to the loss of one eye--and, later, on gases from volcanoes, geysers and blast furnaces. With Kirchoff he contributed to our understanding of the meaning of spectra lines. (He also gained note for not bathing--one woman of polite society remarked that Bunsen was so charming that she would like to kiss him, but she would have to wash him first.) Bunsen invented many bits of laboratory apparatus: the spectroscope, the carbon-pole battery, an ice calorimeter and vapor calorimeter, the thermopile, and the filter pump--but not, as one might imagine, the gas burner that bears his name. Rather, the "Bunsen" burner was developed by Bunsen's laboratory assistant, Peter Desdega. Desdega himself likely borrowed from earlier designs by Aimé Argand and Michael Faraday. So why does Bunsen get the implicit credit? --And why do we know so little about Desdega that we cannot add much to his story?"Bunsen's" burner illustrates an important dimension of science frequently omitted in teaching about science: professional credit. Eponymous laws and labels--whose names reflect their discoverers--appear throughout science: Snell's law of refraction, Gay-Lussac's law of gases, the Hardy-Weinberg model of population genetics, the volt (named for Alexander Volta), etc. The naming of laws for their discoverers seems appropriate for honoring the scientists--and the human names are handy for reminding students that science is done by real persons. But in this system, one person and only one person gets all the credit. Focusing on great individuals can hide the collective nature of science, especially the role of technicians such as Desdega. How do we distribute the credit where appropriate?The great Isaac Newton is frequently quoted for expressing the humbling effect of the collective effort in science: "If I have seen further," he once professed, "it is by standing on the shoulders of giants." Newton's claim, we now know, betrayed a false modesty. Newton's bitter priority dispute with Leibniz over the invention of the calculus, in particular, bears witness to his ambition and obsession with prestige--and his political maneuvers in trying to achieve it. In that case, at least, Newton tried to further his own stature "by standing on the claims of competitors." In similar ways, perhaps, the contributions of technical workers often get buried when we allow theoretical discoveries of the work of their masters to overshadow them. Bunsen's burner--or perhaps the Desdega burner--is a notable example.The story of the Petri dish is an interesting exception--while at the same time underscoring the general pattern of invisible technicians. Julius Richard Petri (1852-1921) worked for the master of "germ theory" in Germany in the late 1800s, Robert Koch (1843-1910; pronounced as a gutteral "coke"). Initially, bacteria were cultured in liquid broth--a practice captured in our famous images of experiments on spontaneous generation. But Koch saw the advantage of growing bacteria on a solid medium instead. By spreading out mixtures of microorganisms on a solid surface, he could separate individual types in isolated colonies. With pure colonies, he could investigate the effects of each bacterium. The method allowed Koch to identify the specific organisms that cause tuberculosis, cholera, diptheria, among many other diseases--and then to develop vaccines.
