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 the form of photons predominately with a wavelength of approximately 475 nm, which we perceive as blue light.
The reaction can be described by the following equation:
CH4 (g) + 2 O2 (g) => CO2 (g) + 2 H2O (g)

What is the balanced equation of a Bunsen burner?
The Bunsen burner is an instrument, not a chemical with a formula. If the fuel is methane the general reaction of combustion is: CH4 + 2 O2 → CO2 + 2 H2O
Why did Robert Bunsen improve the Bunsen burner?
He was a pioneer in Photo Chemistry and also in Organoarsenic chemistry
Different kinds of burner?
Three types of laboratory burners are the Tirrill Burner, Bunsen Burner, and the Meker Burner. The Tirrill and Meker Burner have air and gas adjustments while the Bunsen Burner has only an air adjustment. Hope that helps.
Does magnesium carbonate decompose at Bunsen burner?
Yes, the reaction is: MgCO3 ----------- MgO + CO2
Where do you store a Bunsen burner?
IN a cupboard but make sure there is a plastic basket and the Bunsen burner must be cooled before stored.
Is striking a match to a Bunsen burner a chemical reaCTION?
Striking a match initiates a chemical reacftion (burning). The proximity of the Bunsen burner has nothing to do with it.
What is the name of the chemical reaction happening inside a Bunsen burner?
Combustion.
Is the Bunsen burner.....?
an exothermic reaction or and enothermic reaction
What is the balanced equation of a Bunsen burner?
The Bunsen burner is an instrument, not a chemical with a formula. If the fuel is methane the general reaction of combustion is: CH4 + 2 O2 → CO2 + 2 H2O
How was a Bunsen burner made?
The Bunsen burner was the result of a building lighting approach that Robert Bunsen was trying to implement in a new laboratory building he was entrusted to design for the University of Heidelberg. The building had a gas supply which was thought to be useful for creating heating and lighting capabilities. The Bunsen burner was to regulate this gas supply for these purposes.
What affects the intensity of the combustion reaction of a Bunsen burner?
The intensity of the combustion reaction of a Bunsen Burner is affected by the air supply, which is regulated by how far the air hole is open.
Why it is necessary to hold the neck of the tube in the flame of the Bunsen burner?
It will be safer for us and people around you, in case the chemical will have reaction and spilled out
When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
What is used to make a spark when lighting a Bunsen burner?
A flint is commonly used.
When would a Bunsen burner be used?
To heat-start a chemical reaction. Also it can be used for flame testing of cations. Modern labs. used electric or steam mantles for heating a reaction, because the temperature can be controlled. The Bunsen burner was invented by the German Chemist, Robert Chemist, in the late 19th century, before e;ectric/steam mantles were invented.
Why should you light a Bunsen burner from the side and not the top?
If you light the burner from the top, the lighting instrument will be blowin out by the force of the gas.
How do you change the flame on a Bunsen burner?
To change the flame on a Bunsen burner you need only to open or close the air valve to change the combustion reaction.
