What else can I help you with?
Which substance will burn in bunse to give a brick red non luminous flame?
NaCl will burn with a brick-red colour in a non-luminous Bunsen flame.
Which bunsen burner luminous or non luminous flame used in laboratory and why?
A non-luminous flame is typically used in laboratory settings when using a Bunsen burner. This flame produces a more controlled and homogeneous heat source, making it ideal for processes like heating, sterilizing, and combustion analysis. The non-luminous flame also produces less soot and is more energy efficient compared to a luminous flame.
Why the dominant color of a nonluminous flame on a Bunsen burner blue?
The dominant color of a nonluminous flame on a Bunsen burner is blue. Whereas, the dominant color of a luminous flame on a Bunsen burner is orange.
What colour is the Bunsen burner safety flame?
Yellow/Orange. The blue one is harder to see and hotter.
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.
Should a luminous or non-luminous Bunsen flame be used for heating in the labortary why?
.
Which substance will burn in bunse to give a brick red non luminous flame?
NaCl will burn with a brick-red colour in a non-luminous Bunsen flame.
What are the two kinds of flames produced by Bunsen burner?
The two kinds of flames produced by a Bunsen burner are the luminous flame (yellow flame) and the non-luminous flame (blue flame). The luminous flame is cooler and produces soot, while the non-luminous flame is hotter and ideal for heating and sterilizing.
What are the characteristics of the luminous Bunsen flame?
A luminous flame is blue and is air/oxygen rich and occurs when the Bunsen vent is open. A non-luminous falme is very yellow and smoky and is fuel rich. It occurs when the Bunsen vent is closed.
Why should the Bunsen burner be left with a luminous flame if it is temporarily not in use?
Leaving the Bunsen burner with a luminous flame while not in use helps prevent gas leaks by indicating that the gas is on. It also maintains a constant temperature for when it needs to be used again quickly.
Which bunsen burner luminous or non luminous flame used in laboratory and why?

The non-luminous flame also produces less soot and is more energy efficient compared to a luminous flame.
How would you adjust the Bunsen burner to obtain a luminous flame?
To obtain a luminous flame on a Bunsen burner, adjust the air intake to decrease the amount of oxygen mixing with the gas. This can be done by partially closing the air hole at the base of the Bunsen burner. This will result in an incomplete combustion of the fuel, producing a yellow, sooty flame.
Which flame should one use if he is leaving a Bunsen burner unattended?
Luminous since it is visible
Which portion of the luminous flame is the coolest?
For a Bunsen burner the lowest temperature is in the extreme lower part of the flame.
Why do you turn off the bunsen burner for the remainder of the experiment?
no idea
What is the thing for heating objects in science?
The device used for heating objects in science is called a heat source. This can come in the form of a Bunsen burner, hot plate, or an oven, depending on the specific experiment or process being carried out. Heating objects is often necessary to initiate chemical reactions or change the physical properties of a substance.
Why you need to continue open the Bunsen burner when the experiment?
Continuing to keep the Bunsen burner open during the experiment ensures a stable flame for heating. It helps maintain a consistent temperature during the process, which is crucial for accurate and reliable results. Closing the Bunsen burner can cause fluctuations in temperature and affect the outcome of the experiment.
