The dominant color of a non-luminous flame is blue because incomplete combustion occurs. This means that there is not enough oxygen present to completely burn the fuel, resulting in the production of carbon monoxide and other compounds that emit a blue color when they release energy in the form of light.

Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
What colour is the Bunsen burner safety flame?
Yellow/Orange. The blue one is harder to see and hotter.
Why is non luminous blue flame preferred over the luminous yellow flame in the laboratory?
blue flame is more important for laboratory procedures since it's also known as the reducing zone of the flame in which the tip of the blue flame has the highest temperature. and thank you , a Dental student ;D
Is the inner part of a luminous flame yellow?
Yes, the inner part of a luminous flame is typically yellow. The yellow color is due to the incomplete combustion of carbon particles present in the flame.
How can a student change a luminowhat would need to be done to a Bunsen in order to change a luminous yellow flame into a non luminous blue flameus yellow flame into a non luminous blue flame?
A blue flame contains lots of oxygen compared to the yellow flame. So the only thing you should do is decrease the oxygen supply
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
Why the dominant color of a non luminous flame on a Bunsen burner is blue?
The dominant color of a non-luminous flame on a Bunsen burner is blue because the fuel (typically natural gas or methane) is burning efficiently and completely. The blue color indicates that there is enough oxygen present for complete combustion, resulting in a clean, hot flame.
What is the dominant color of a luminous flame in a Bunsen Burner?
the orange flame (when the oxygen wholes are closed it makes an orange flame) because when it is on the blue flame (when the oxygen wholes are open) it is very hard to see and almost invisible
What kind of flame is non luminous?
No-luminous flames, with a blue color, are formed when the oxygen is in excess.
Is the temperature of a luminous flame greater ot less than that of a nonluminous flame?
The yellow color in a luminous flame is basically the black-body emission from hot particles of soot in the flame. they are hot, and they glow like the filament of a light bulb. In a blue flame, there are no particles of soot to give that incandescent radiation. Instead, the main color you see is blue emission from the high-energy C2 molecule.
Which part of a non-luminous flame is hottest?
The hottest part of a non-luminous flame is the inner cone, which is typically blue in color. This is where complete combustion of the fuel occurs, resulting in the highest temperatures.
Why can the yellow or luminous flame not be used in flame testing?
The yellow or luminous flame cannot be used in flame testing because it can mask the true color emitted by the metal ions present in the sample being tested. It is best to use a blue or non-luminous flame, as it provides a clean burning environment that allows for accurate observation of the characteristic flame color produced by the metal ions.
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.
Is the temperature of a luminous flame greater or less than that of a nonluminous flame?
a non-luminous flame- when the air hole of the Bunsen Burner is open"when the air hole is open, more oxygen can enter the burner; therefore, hotter flame will be produced."its color is transparent or blueBlue flames are the hottest flamesa luminous flame is produced when the air hole is closed.."if the air hole is closed, oxygen cannot enter the burner; therefore, least hotter because the combustion is not fully complete with least oxygenA luminous flame has an outer of orange color and an inner of blue.Luminous flames emits more light than non-luminous flames.three things to produce flame1.fuel2.oxygen3.friction or source of sparkLuminous objects emit light. The sun is luminous; the moon is non-luminous.
What colour is the Bunsen burner safety flame?
Yellow/Orange. The blue one is harder to see and hotter.
What is luminous flame and Explain why it takes a longer time to heat equal amount of water using a luminous flame?
yellow color in a luminous flame produces soot or carbon. carbon dioxide is present in the luminous flame but when its combined with oxygen the flame is nonluminous which is in a blue color. it takes a longer time because luminous flame is cooler than the nonluminous. I only know what luminous flame is. The inner part of luminous flame is blue while the outer part of the luminous flame is yellow. It is unsteady. Yeah. Carbon Dioxide is only present in the luminous flame. When oxygen is combined with the flame, the flame will become non- luminous which is inner and outer part are blue. Hmm. Actually luminous flame's hottest part is at the bottom while non- luminous flame hottest part is at the middle and the top. That's all i know. If i know more, i will update for you. Thank you!

What is the name of the blue flame?
The blue flame is commonly known as a "butane flame" or a "clean burning flame." It occurs when a gas like butane is burned cleanly, resulting in a hotter and more efficient flame that appears blue in color.
