Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
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.
Is flammability a chemical property that tells whether a substance reacts to the presence of carbon dioxide?
oxygen
Why does the black soot formed?
A small stable flame of a candle has a lot less black smoke than a larger flickering flame. Air around the burning candle causes this to happen.
What flame is what you called when air holes are closed?
Safety flame
Does a non luminous flame produce a lot of carbon residue?
Yes, it does produce more carbon.
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
What color does sugar produce you n a flame test?
Flame of itself is yellow/white. This is white hot carbon particles. Carbon, per se, does not form ions and so cannot give a flame test colour.
What is flame safety?
A Safety Flame Is The Yellowy Orange Flame. It Is Called A Safety Flame Because You Can See It Unlike The Blue Flame
Why is the yellow flame the safety flame?
Yellow flame can be seen easily and it doens't produce much heat.
What do you have to do to get a safety flame?
There is no such thing as a safety flame.
Can a blue flame produce CO?
No, if the flame is totally blue and/or has no yellow, then that indicates complete combustion which results carbon dioxide [CO2] and water vapor, but no carbon monoxide [CO].
Is the roaring flame smaller than the safety flame?
safety flame
Why is a yellow flame called dirty flame?
Tends to deposit black unburned carbon residues derived from the gas etc.
How does a person make a cold fire?
Cold fire is often used by jugglers and flame eaters. It can be made by immersing an object in a mixture of carbon disulfide and carbon tetrachloride. This will produce a flame but it will only be warm. Extreme care should be taken however as it will produce a noxious acrid smoke and carbon tetrachloride is carcinogenic.
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.
On a Bunsen burner which flame produces a sooty carbon black deposit on whatever it heats?
I Believe It Is The Roaring But I Am Not Sure. When We Put A Test Tube Into The Roaring Flame, I Think It Turns That Part Black. It May Be The Medium Flame.
