What make gas flame luminous?
There is a lack of oxygen in the flame itself (most probably because of the air holes in the Bunsen burner or of your burning device) this effect would create a luminous flame (better known as a yellow flame). A kind of flame that does not burn as hot as a non-luminous flame (better known as a blue flame)
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
How can a student change a luminowhat would need to be done to a Bunsen in order to change a luminous yellow flame into a non luminous blue flameus yellow flame into a non luminous blue flame?
A blue flame contains lots of oxygen compared to the yellow flame. So the only thing you should do is decrease the oxygen supply
When magnesium ribbon is bought near the Bunsen flame it catches fire and the colour of the flame produced would be?
The flame is white and very luminous.
What is another name for the Bunsen burner?
you would use the safety flame when not heating anything because the blue flame is for heating because its hotter than yellow.
What kind of flame would you use if you have to boil a solution?
Non luminous flame

Why is it necessary to use non-luminous flame in flame test?
because the non-luminous flame has a higher temperature and the natural spectra of the metal is noticed.

How would you adjust the Bunsen burner to obtain a luminous flame?
Rotating the barrel of the burner.

Suggest two reasons why a luminous flame is not used as a source of heat in a laboratory experiment?
It produces more heat. It does not produce soot that would stain the laboratory apparatus.
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
Why does it take time for a match stick to ignite in a non-luminous flame?
A non-luminous flame is a flame colored blue, and is undergoing almost-perfect or perfect combustion. Matchsticks emit luminous flames, which burn red to yellow and aren't as perfect. Matches take a second to reach full flame when put in a Bunsen burner (which emits a non-luminous flame) because the ignition of the match normally is based on the spark produced by swiping the match, which produces massive heat in a split moment. With the Bunsen burner, it takes a second for the match to reach the heat level required for ignition.
What is the yellow flame on a Bunsen burner used for?
It indicates that the air hole is closed. The yellow flame is also called the luminous flame and the safety flame. It is luminous due to small soot particles in the flame which are heated to incandescence. The yellow flame is considered "dirty" because it leaves a layer of carbon on whatever it is heating.It is considered safe as it is more visible than the near invisible and hot non-luminous flame (it can be obtained by half opening the air hole) as people would not mistake it as switched off and touch it. It is usually not used for heating as it's not as hot as the non-luminous flame(also called the blue flame). The blue flame is hotter as it produces more heat energy than light energy, comparing it to the yellow flame, which produces more light energy than heat energy.
