How a Bunsen burner can display both complete and incomplete combustion?
Wiki User
∙ 6y ago
The Bunsen burner would display complete combustion by producing a "roaring" blue flame and it would display incomplete combustion when you close the air valve complete to cut off the oxygen gas supply, thus creating a yellow flame due to the burning of carbon particles (soot).

Where do carbon atoms come from in a Bunsen burner?
Carbon particles are created by incomplete combustion of the methane gas. The balance chemical formula for the combustion taking place is as follows: CH4(g) + 2O2(g) ---> 2H2O (g) + CO2(g)
What Bunsen burner flames show complete combustion?
the blue one because oxygen can get to it through the air hole :) hope this helped
How does a yellow flame on a Bunsen burner make things black but the roaring flame doesn't?
The flame of a Bunsen burner that is yellow in color will leave a black carbon residue due to the incorrect mixture of oxygen into the flame. Because there is not enough oxygen for complete combustion, the carbon reside is left behind. When the Bunsen flame has a sufficient amount of oxygen mixed in, hence the 'roaring flame', it has a blue color and does not leave a carbon residue due to complete combustion of the acetylene gas.
In a lab what is used for heating combustion and sterilization?
A Bunsen Burner.
What is the chemical equation of reaction that occurs when natural gas burns?
Natural gas is mixture of gases, but is usually considered to be methane. The equations for the combustion of methane is of course pretty basic. Combustion or burning means you add oxygen gas (O2) which you will remember is diatomic. The products are always assumed to be carbon dioxide (CO2) and water. The complete combustion reactions is this CH4 + 2 O2 --> CO2 + 2 H2O and gives the blue flame in your bunsen burner or gas stove. By the way, the yellow, sooty flame is incomplete combustion and has this reaction CH4 + O2 --> C + 2 H2O .
Why is the Bunsen burner smokeless?
Smoke is a product of incomplete combustion. When used properly a Bunsen burner propduces complete combustion, which is made evident by a blue flame.
How do you regulate the size of a flame when using a Bunsen Burner?
by limiting the amount of oxygen you can get incomplete combustion where the flame is coolest and complete where it goes blue and is bare hot
What is a disadvantage of incomplete combustion when Bunsen burner is stopped?
if the incomplete combustion keeps going there you will have carbon monoxide poisoning if it is left untreated it can kill you it will bind with your blood cells and stop oxygenated blood from going around your body
What causes the luminescence in the cooler yellow flame on Bunsen burner?
The luminescence in the cooler yellow flame is caused by closing the air vents of a Bunsen burner. This is the result of incomplete combustion.
What dos a Bunsen burner do when the air hole is clos?
When you close the air valve of a Bunsen burner the flame turns yellow due to incomplete combustion and the ignition of carbon particles (soot).
When air hole of the Bunsen burner is closed what is the observation?
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.

What causes the Bunsen burner sometimes have a blue flame and sometimes an orange flame?
The blue flame is observable when complete combustion occurs, which is when the air valve is opened enough to allow the ideal amount of oxygen. The orange flame is due to the burning of carbon particles (soot) caused by incomplete combustion, which is an effect of too little oxygen available for the reaction.
Color of flame in a complete combustion of gas from Bunsen burner?
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 blue flame which is the product of complete combustion. Hope this helped :)
Why is copper wire turned into grayish black when it heated on a Bunsen burner?
The black which forms on the copper is most likely carbon, produced from in complete combustion. This incomplete combustion occurs when not enough oxygen is present for all the fuel to combust. If you are using a Bunsen burner you are most likely using methane as a fuel, incomplete reaction can result in: CH4(g) + O2(g) ---> C(s) + 2H2O(g)
Does the Bunsen burner absorb energy as heat?
The Bunsen burner release energy as heat of combustion.
