Luminous flames produce soot due to incomplete combustion of carbon-containing compounds. When there is insufficient oxygen available for combustion, carbon particles are not fully oxidized and are instead released as soot. The presence of soot in the flame causes it to appear yellow or orange and gives off visible light. To minimize the production of soot, it is important to ensure proper ventilation and sufficient oxygen supply for complete combustion to occur.

Why is it advisable to turn a luminous flame to a non luminous flame when the flame is not in use?
Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
Should a luminous or non luminous Bunsen flame be used for heating in the laboratory and why?
Non-luminous flame should be used for heating in the laboratory because the flame is steady and produce little or no soot.Non-luminous flame is very hot thus, it is recommendable to use for laboratory purposes.Luminous flame is unsteady while non-luminous flame is steady.Another reason of using non-luminous flame because the flame of non-luminous is blue, and not visible unlike the luminous flame which is yellow in colour and visible.
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.
How does luminous flame exist?
A luminous flame is produced when a chemical reaction (such as combustion) releases energy in the form of light. The presence of solid particles or molecules in the flame can also contribute to its luminosity by emitting light as they are heated. This is different from a non-luminous flame, which does not produce visible light.
Characteristics of luminous flame?
Non luminous zone is the zone of a flame which is also the hottest zone of the flame as it is mostly in contact with oxygen. It is also called invisible zone.
Is sooty flame a luminous or non luminous?
A sooty flame is typically considered a non-luminous flame because it does not produce significant visible light. It appears dark or dim due to the presence of unburned carbon particles (soot) in the flame.
Why is it bad 2 heat things with a luminous flame?
Heating things with a luminous flame can produce soot, which is a black carbon-based substance that can contaminate the item being heated. In addition, soot can also pose health risks if inhaled. It is better to use a clean, non-luminous flame for heating to avoid these issues.
What is the difference between luminous and non luminous?
-A non-luminous flame is when the air hole of the Bunsen burner is closed but a luminous flame is produced when the air hole is opened.-A luminous flame has an outer of orange colour and an inner of blue. A non-luminous flame has an outer of blue and an inner of orange.-A luminous flame produces soot while a non-luminous does not produce soot.-A luminous flame is weak and unsteady. A non-luminous flame is strong and steady.-A non-luminous flame is very hot while a luminous flame is not too hot.
Why is it advisable to turn a luminous flame to a non luminous flame when the flame is not in use?
Turning a luminous flame to a non-luminous flame when not in use conserves fuel because non-luminous flames burn more efficiently. A non-luminous flame produces less soot and smoke, making it safer and better for indoor air quality.
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

Which type of flame should use in laboratory luminous or non luminous?
Non- luminous flame should be used as it is steady and produces little or no soot.
How the flame produced when the air holes were closed. if the the flame was luminous what made it so?
When air holes are closed, oxygen supply decreases, leading to incomplete combustion and the production of soot particles. These soot particles can get heated up to incandescence and emit visible light, creating a luminous flame. The presence of carbon in the soot is what causes the flame to appear luminous.
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.
Why is black soot formed when the flame is luminous?
The black deposit produced represents soot particles, heated to incandescence. It comes about when the combustion of air is insufficient.
