Bunsen Burners

Parent Category: Chemistry
The Bunsen burner was named after Robert Bunsen. It is commonly used in science laboratories. This category contains questions relating to the Bunsen burner, its use and its history.
The base of a Bunsen burner allows it to remain stable whilestanding.
The bunsen burner is used to heat items for experiments using acontrollable temperature flame and surface area at which the heatis applied to the vessel.
Metal. Usually an iron alloy or aluminum.
Yes, because a gas is burned - an oxydation reaction. This chemical reaction produces heat as well as carbon dioxide and water vapor as products from methane and oxygen gas. The heat also excites the electrons in the gases it produces, causing them to gain energy and rapidly emit this energy in...
well there is alot of them . be careful . turn the gas on . make sure there is no cracks in the gas tube . make sure you are weiring in a fireproof bench . keep stuff away from it . before turning on the gas light a match/spilnt and hold it to the bottom on the chimney of the bunser burner ....
Because it takes some time for the burner to light, and in this time, paper would burn down and away from the gas at the top of the barrel. A splint will only smoulder near the barrel, for more than long enough.
The gas in a bunsen burner comes from a hose attached to a tank.Before that the gas comes from deep in the earth as raw naturalgas.
The water will turn into water vapor which is gaseous H2O. If thevessel is not strong enough to withstand the increased pressureapplied in all directions the vessel will open or break ifpossible. Otherwise the pressure will just increase based on howmuch steam is created.
Robert Bunsen invented the Bunsen Burner in 1867.
It is easier to see when it is yellow. It produces more heat energy and less light energy when it is blue. The yellow flame produces more light energy than heat energy. That makes it more visible
Iodine is used for starch test.
If u put ur face up to it, you'll know what will happen, idiot!.~.!
When the air hole is covered on the Bunsen Burner its oxygen supply is made smaller. This makes the flame turn YELLOW - This is considered to be the safety flame as it is the most visible to the eye and it radiates less heat. When the Bunsen burners air hole is fully open there is a super heated...
an exothermic reaction or and enothermic reaction
When sterilizing a loop, grasp the handle firmly and begin flaming it starting at the end near the grip, flaming slowly down towards the loop, being sure that the wire is glowing orange. This ensures that the loop is being flamed properly and sterilizing.
When the air hole is opened completely then the flame would turn blue indicating it is very hot. If you closed it the flame will be yellow indicating that it is not as hot (also called the safety flame). So if you half opened the hole then the flame would be hot but not as hot as the blue flame, due...
The approx. temperature on a blue Bunsen burner flame is about 110 degrees Celsius, but this depends on your Bunsen burner
Any flammable gas but usually coal-gas + oxygen.
70 degrees and the roaring flame is 100 degrees so yeah hot hot dont touch
fill the testube with the liquid and put in a test tube holder light the Bunsen and adjust to the blue flame pick up the test tube with testube clamp/tongs hold it over the flame on a slight angle away from yourself swirl continuously so that it heats evenly
The tip of the blue cone is the hottest part of the Bunsen burner flame..
Air hole, collar, barrel, base, burner tubing
No. The blue flame is called the roaring flame because it makes a sort of hissing sound, it is also not called the safety flame because it emits very little light so it is a hazard. It is a hazard because you can not see it very well so it is dangerous.
It is to prevent direct contact of the glass with the flame of the Bunsen burner. This lowers the possibility of the glass shattering when being heated Read more: http://wiki.answers.com/Q/What_is_the_purpose_of_the_wire_gauze_placed_over_a_bunsen_burner#ixzz1ljq5rSMO
The blue flame is really hotter than the yellow flame. If you put your hand over a blue flame and skim through it, it would burn you but if you put it over a yellow flame it wouldn't burn you that much.
If you use Bunsen burner, you might burn the volatile liquid. Also, because it is organic, the fire would likely spread to you because it would burn too fast for you to react.
Because it is 'dirty', meaning it leaves soot. Also because it isn't that hot.
as far as i know on top of the barrel is the flame. i think that's right
See the link below.
you could get burned and you could burn the buffet food....
Because you'll burn the heck out of yourself if you tried it!
Yes, provided the paper has been lit first.
You adjust a rotatable thing at the bottom, normally there is a hole that will become either closed or open to change the flame.
A small fire. Remember, people didn't need Bunsen burners until they needed a constant source of heat. By the time that science required such a thing, manufacturing had advanced to the point where Bunsen burners were easy to create.
If you see blue it means that the flame is hotter. It will then (obviously) heat up whatever it is faster.
because it makes you burn up cause your a twit
Mr Robert wanted to makes something that will saute his name
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
The "air holes, or the gas is too high.
If you let hydrogen gas near the flame it will pop. The way we got hydrogen gas is by adding hydrochloric acid to magnesium powder and putting our thumb over the top of the test tube trapping the hydrogen gas then releasing it near the flame of the Bunsen burner.
By adding more oxygen to the burner. Fire requries oxygen
a Bunsen burner flame can be 20* to 2000*
the maximum temperature that can be achieved by the blue flame of a Bunsen burner if air is used is upto 1500 o C.
Its inventor Robert Bunsen
The hottest part of the Bunsen burner is the part on top of the blue cone
It is to prevent direct contact of the glass with the flame of the Bunsen burner. This lowers the possibility of the glass shattering when being heated.
Yes, you can melt silver with a Bunsen burner. In fact, you can melt any metal using a Bunsen burner, just so long as you have the patience and time! Ribbit! xoxoxoxoxox
Boric Acid! When boron is heated, electrons absorb a certain amount of heat energy that causes them to jump to higher energy levels. After While, these electrons lose their energy and fall back down to their original levels, and as they do so, they emit energy in the form of light. Because the...
The yellow flame in a Bunsen burner can be as hot as 1000 degrees in centigrade scale.
Robert Bunsen investigated the emission spectra of heated elements and helped to discover cesium and rubidium. He also invented the use of iron oxide hydrate to treat arsenic poisoning, which is still used.
Outer oxidizing zone middle reducing zone inner unburned gases
The blue flame is called a roaring flame and the yellow flame is called the safety flame.
If you turn it to the "Roaring Blue Flame" you should see a small blue cone within the actual flame, the hottest part is actually just above that cone, contrary to common mistake that it is inside the "blue cone". The blue cone is just the gas that has not been ignited yet.
The Bunsen burner is an instrument, not a chemical with a formula. If the fuel is methane the general reaction of combustion is: CH 4 + 2 O 2 → CO 2 + 2 H 2 O
NO!! it is EXTREMELY flammable so any spark would cause a massive fire and even explosion. I just read that the boiling point is 35 degrees C
No, the blue part is the hottest.  In fact, you should adjust the burner so that you only have a blue flame.  A yellow/orange/red flame is indicative of incomplete combustion (generating carbon monoxide).. \n
With oxygen closed off and a yellow flame the temperature is about 1000 degrees Celsius.
the cleanes t flame is the blue flame
to heat certain things e.g water, rocks etc
Check that the valve is half open, light the match, and turn on the gas to the appropriate level.
You would have to close the collar instead of opening it. This will produce a yellow flame. But it is not suitable for heating. Only a blue flame is suitable for heating as it is much hotter than a yellow flame. M.F. - The yellow smoky flame is the lack of Oxygen (O 2 ) mixing with the...
So you don't burn yourself. If it's on and you're not paying attention to it, a luminous flame is easily glimpsed in your peripheral vision. If the flame was non-luminous, it's much harder to detect and causes a greater risk. the non-luminous flame also burns much hotter.
Turn off the fuel source, eg close the gas tap
Robert Bunsen Robert Bunsen was the inventor of the Bunsen burner.
When set to a roaring flame, there are what looks like cones of different shades of blue and orange. The hottest part of the flame, when set to roaring, is at the tip of the blue cone.
Ingredients separate since oil & vinegar don't mix.
A Bunsen burner licence is a certificate recognising a student's ability to correctly light a Bunsen burner. It may also require the student to name the parts of a Bunsen burner. yo go boy babe
Methane + oxygen gas ------> carbon dioxide and water (CH4 + 2 02 ------> C02 + 2 H20 )
it destroys the world, but if veryone is dead, WHO WAS PHONE? Well it boils away and because the vapour is is inflammable you will get a fire. Inflammable volatile substances should never be heated up using a naked flame, its dangerous.
It becomes less viscous, and gives off more vapors(evaporation).
The hottest flame is the blue flame and the coolest flame is yellow.
You could blow up the bunsen burner.

the Ka of salicylic acid is 1.07 x 10 -3 . the pKa of salicylic acid is 2.97
Sounds like a bad Universal Joint.SOMETIMES a bad Transmission Mount will do the same thing. Answer I know this sounds odd ! When was the last time you changed the plugs and wires? This happened to me and I changed them all out and gave it a tune up and it stopped.GOOD LUCK! !!!!!!I really know...
