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.
When do you get yellow soot in the burner flame?
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
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.
Is the yellow flame on a Bunsen burner the unburnt gas?
No. The yellow flame is actually due to incomplete combustion because of a lack of oxygen gas (air intake) and as a result carbon particles (soot) get ignited causing the yellow flame.
Why does a non luminous zone produce less residue as compared to a luminous one?
In the luminous zone of a flame solids such as carbon are produced because there is only a small supply of oxygen to burn the fuel. In the non-luminous zone there is more oxygen and the fuel is completely oxidised to gases such as carbon dioxide.
Is fuel consumption harmful to environment?
burning carbon fuels like wood,coal& pettroleum relaese unburnt carbon particles to the environment.THEY sometimes causes Respiratory diseases such as asthma.
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.
Why is a luminous flame formed when the air hole is closed?
The luminous flame is present when the air valve is closed because of an incomplete combustion process and the burning of trapped carbon (soot).
What does a catalytic converter do on a 1997 dodge 5.9l?
It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.It converts carbon monoxide, nitrous oxides and unburnt fuel into carbon dioxide, nitrogen, and water vapor.
Why do spark pugs turn black?
Unburnt carbon
When do you get yellow soot in the burner flame?
Yellow soot is obtained when the holes of the burner are not clean. The combustion is incomplete. The yellow soot or yellow flame is because of unburnt carbon particles.
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 for bits of unburnt carbon?
charcoal graphite diamond
What can cause black carbon from the exhaust?
It would be unburnt fuel
Why luminous flame produce soot?
Soot means dark black smoke, it is due to unburned particles of carbon. when a compound (specially aromatic) has a high ratio of carbon then on combustion all the carbon is not converted into carbon dioxide but escaped out as unburned particles.
Does smoke create rainbows?
Light passing through a transparent medium like glass/water does. Smoke is made of small particles of unburnt carbon, and light passing through is does not get split into a rainbow.
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.
