What kind of flame is a yellow flame called?
A yellow flame is named as a safety flame as it isn't as hot as the blue flame
Which flame is not suitable for heating in Bunsen burner?
The yellow flame (or luminous flame) should not be used because 1. It is less hot that the blue flame (or non-luminous flame) 2. It produces soot, as compared to the blue flame which is the clean flame
Why is the safety yellow flame important in the laboratory?
The yellow flame is called the safety flame because you can see it very well, whereas the blue flame emits very little light so it is not very easy to see. Therefore the yellow flame is called the safety flame because it emits the most light.
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.
Which flame is not suitable for heating in Bunsen burner and why?
The yellow flame because that is the safety flame

What happens when a Bunsen burner air hole is half open?
When the air hole is opened completely then the flame would turn blue indicating it is very hot. If you closed it the flame will be yellow indicating that it is not as hot (also called the safety flame). So if you half opened the hole then the flame would be hot but not as hot as the blue flame, due to the air flow mixing with the gas inside.
