What controls the gas mixture in a Bunsen burner?
The gas flow control valve on a Bunsen burner regulates the amount of gas entering the burner, while the air hole at the bottom adjusts the air mixture. By adjusting these two components, the user can control the gas mixture and achieve either a lean (more air) or rich (less air) flame.
What are the two colors of a Bunsen burner flame?
The two colours are yellow - when the air-hole is open, and blue - when the air-hole is closed.
What are the two kinds of flames produced by Bunsen burner?
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
Parts of a Bunsen burner adjusted?
There are two adjustable parts on the Bunsen burner, the knob to control gas flow and the rotation of the collar to control air flow. The gas flow control, adjusts the size of the flame by controlling how much gas is burned. While the collar controls the intensity of the flame by controlling how completely the gas burns, more complete combustion the hotter the flame. These are the two parts to adjust a Bunsen burner, I hope I have answered your question.
Who found rubidium?
German chemists Robert Bunsen and Gustav Kirchhoff discovered rubidium in 1861 by the newly developed method of flame spectroscopy Rubidium was discovered in 1861 by German chemists Robert Bunsen and Gustav Kirchhoff through flame spectroscopy. Flame spectroscopy involve taking the substance to be analzed, coating a wire in it, and holding the wire inside of the flame of a Bunsen Burner (guess who invented this! See above). The color of the flame is then recorded.
What did Mr Bunsen invent?
Robert Bunsen did NOT invent the Bunsen burner. It was his assistant Peter Desaga, who developed it. He discovered two new elements, the metals caesium and rubidium.
How many holes are in a Bunsen burner?
only two holes
What two substances are reacting when a Bunsen Burner is ignited?
The substances of methane (CH4), also known as natural gas, and air (O2) mix to start a Bunsen Burner.
What are the two energy regions in a Bunsen burner?
The two energy regions in a Bunsen burner are the inner blue cone, which is the hottest part of the flame and is where combustion occurs, and the outer yellow flame, which is cooler and is responsible for creating a visible flame.
What are the two regions in a Bunsen burner?
What are the two regions in a Bunsen burner? The two regions in a Bunsen burner flame are: 1.An outer transparent, dim blue cone. 2.An inner,less transparent, brighter greenish-blue cone. This relatively non luminous,cone shaped flame is a combustion of carbon-hydrogen fuel which is used in a Bunsen burner to provide heat for laboratory purposes.
What kind of flame are produced by the Bunsen burner?
The two types of flames a Bunsen burner can produce are a luminous, yellow flame and a "roaring" blue flame. The blue flame is much hotter than the yellow flame.

How do the Bunsen burner looks like?
I prefer a number-two pencil and sheet of fine copier paper when drawing pictures of laboratory equipment. But the technique is pretty simple: you either get a Bunsen burner from the lab, or download a photo of one from the Internet, and sketch it.
What were Bunsen's other achievements other than the invention of the Bunsen burner?
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.
Who discovered censium?
Cesium was discovered by two men named Fustov Kirchoff and Robert Bunsen, in the year 1860.
