What do you call a flame on a Bunsen burner when the air hole is half open?
air hole closed- flame is the standard yellow-orange color air hole half open- flame is a violet-blue color air hole open- roaring blue flame
What is the equation for the safety flame on a Bunsen burner?
There is no equation for a flame. You can try to write an equation for the reactions happening in the region we call the flame. I presume you mean when the air hole is closed and the flame is yellow. There is no one simple equation, as several reactions are going on, but this one accounts for the formation of the soot particles which give the flame its yellow colour:CH4 +O2 --> C + 2H2O
What is one hazard with the blue flame?
Yellow flame means there's not enough air to completely burn all the fuel, so more carbon monoxide is formed. - - - - - It isnt the blue flame is more dangerous because you cannot see it.
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.
Suggest why the bule flame is noisiet than the yellow?
More heat is given off, so more variations in the air are produced, making sound.
Why is a blue flame noisier than the yellow flame?
A blue flame is louder than a yellow flame because there is more oxygen (air) flow present than with a yellow flame. The yellow flame indicates a lack of oxygen and incomplete combustion of the methane gas.
How can you fix the yellow flame in Bunsen burner?
Open the collar to let more air enter the burner. This will produce a bluer and fiercer flame.
What happened to the flame when you slowly opened the air holes?
As more air enters the Bunsen Burner, the flame turns from a flickering (wax candle effect) yellow to a fierce sounding blue, much hotter, flame.
How can you tell if there is too much air mixing with the gas in a Bunsen burner?
The more air the fiercer the flame and the hotter the flame.
Which is dangerous the yellow flame or the blue flame?
A blue flame is hotter than a yellow flame. First, "...the blue flame..." IS NOT more dangerous than "...the yellow flame." The yellow flame is more dangerous because it is an indicator of IMCOMPLETE COMBUSTION resulting from burning with a shortage of air, and thus not enough oxygen. The reason this is dangerous, actually DEADLY, is that when combustion [burning] occurs in an oxygen deficient atmosphere, one of the major byproducts of that combustion process is CARBON MONOXIDE, a colorless, odorless, and tasteless gas which is toxic and therefore deadly to any creature that breathes air.
Is the blue flame hotter then then the yellow flame?
Yes it is. Because it gets more oxygen do therefore its hotter. It burns the air up and becomes blue.
How would a burner which has a yellow and smokey flame be adjusted?
Rotating the barrels for the access of more air (oxygen).

When evaporating dish is held over the flame ( air holes are closed )?
I assume the air holes are on a bunsen burner? In which case, when the air hole is closed the flame glows yellow, is less hot, and is more like the flame on a wax candle. When the air hole is opened, air is drawn in and the flame burns blue and produces a fiercer heat.

How do you obtain blue flame on burn-sen burner?
Increase the air flow by opening the circular valve on the stem of the burner. This will cause the flame to burn more intensely and with a blue flame. When the valve is closed, the flame will burn yellow and cooler - more like a wax candle's flame.
What is the hottest part of the flame from a Bunsen burner?
The hottest part is where the flame is light blue or blue; which gradually turns to yellow as the flame is cooled by the colder outer air. When the safety flame (yellow) is on, the hottest point is the tip of this flame.
