What happen to the charcoal if you spray to the non-luminous flame?
If you spray charcoal onto a non-luminous flame, the charcoal will burn due to the presence of oxygen in the flame. The heat from the flame will cause the charcoal to ignite and combust, creating a bright and hot flame.
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.
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.
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.
Why is it necessary to use non-luminous flame in flame test?
Using a non-luminous flame in a flame test ensures that the color produced is due to the metal ion itself and not any additional color from the burning fuel. This allows for accurate identification of the metal ions present in the sample based on the specific color produced in the flame.

What happens to powdered charcoal over the non luminous flame?
When powdered charcoal is exposed to a non-luminous flame, it undergoes combustion. The heat from the flame ignites the charcoal, causing it to react with oxygen in the air, resulting in the production of carbon dioxide and heat. This process can also produce carbon monoxide if there is insufficient oxygen. The flame may appear brighter as the charcoal burns, and it will eventually turn to ash as it is consumed.

What happen to the color of the flame when powdered charcoal was sprayed on it?
When powdered charcoal is sprayed onto a flame, the color of the flame may turn a bright orange or yellow due to the carbon particles burning and emitting light. The charcoal acts as a fuel source, enhancing the combustion process and intensifying the color of the flame.
What kind of flame is non luminous?
No-luminous flames, with a blue color, are formed when the oxygen is in excess.
What color flame test does activated charcoal?
green

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.
What happens to a nichrome wire in a non-luminous flame?
A nichrome wire will not burn or react in a non-luminous flame as it is a highly stable and heat-resistant material. It will retain its structure and properties without undergoing any significant changes.
What is makes the flame luminous?
How: by opening up the air hole on a Bunsen burner after it is turned on.........What: Some atoms or molecules are not luminous when hot. They emit light outside the spectrum we can see, like CO2 emits infrared. Others only emit a faint color in the flame.The non-luminous is made when there is a complete combustion or complete burning process. It happens when there is more than the enough oxygen in the surroundings or in the place where the process will happen.
