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.
Give two reasons why the yellow flame is safer on busen burner?
The yellow flame on a Bunsen burner is cooler than a blue flame, reducing the risk of burns or overheating materials. Additionally, the yellow flame produces less UV radiation compared to a blue flame, making it safer for experiments involving light-sensitive materials.
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 make gas flame luminous?
A luminous gas flame appears yellow or orange due to incomplete combustion, which produces soot particles that emit light when heated. The mixture of fuel and air in the flame is not perfectly balanced, leading to an excess of fuel that results in the incomplete combustion process.
What is a Bunsen burner and its parts and how is it used?
From Wikipedia (see Link to the left):A Bunsen burner is a device used in scientific laboratories for heating, sterilization, and many other uses.The device safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquified petroleum gas such as propane, butane, or a mixture of both.From ScienceByJones.com (see Link to the left):The Bunsen burner is used frequently in the laboratory as a source of heat. This burner is designed so that gaseous fuel may be mixed with the correct amount of air to yield the maximum amount of heat. In order to use this burner properly and safely, it is essential that you understand its construction and the adjustments that can be made.The three principal parts of the burner are: barrel, needle valve, and base. The quantity of gas admitted to the burner is controlled by the needle valve, while the air needed for combustion is admitted at the small opening around the bottom of the barrel. The air is controlled by turning the barrel so as to make the air holes larger or smaller.Always open the desk outlet valve fully and regulate the gas supply to the burner by the needle valve. Always extinguish your burner by turning off the desk outlet valve (and then closing the needle valve and barrel.) If there is an accident always shut off the desk outlet valve immediately.STEPS TO LIGHT BUNSEN BURNER:1. Check connections to burner and desk outlet valve.2. Close needle valve and barrel.3. Open desk outlet valve fully.4. Check for leaks with flame.5. While holding flame above barrel, open needle valve 1/2 turn.6. Adjust barrel and needle valve for blue in blue flame.Always light burner in open space on lab counter. After you have adjusted it for the flame needed move it into position. One person in lab group is always responsible for maintaining the burner and flame.Burner Procedure:1. Light the burner according to our rules. Observe the yellow flame which is produced because not enough air is admitted to give complete combustion. The yellow color is caused by small particles of unburned carbon which become incandescent.2. Now rotate the barrel until the flame is entirely blue. Two different zones should appear when the burner is correctly adjusted. Too much air should not be admitted as it may cool the flame or blow it out entirely. After having the teacher confirm a good hot, blue flame draw a diagram of the flame (use labels and descriptions). Indicate on your diagram of the flame where the hottest part of the flame is located.See the Web Links to the left for more information.Bunsen burner barrels can be rotated, either opening or closing the barrel, to adjust the flow of air or oxygen, thereby controlling the flame.
How do you get a safety flame with Bunsen burner?
To achieve a safety flame with a Bunsen burner, first close the air inlet by turning the collar clockwise to reduce the amount of air entering the burner. Then, light the burner and adjust the air inlet until you get a steady blue flame with a sharp inner blue cone. This will produce a hot and efficient flame while minimizing the risk of accidents.
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 science equipment used to give flame?
A Bunsen burner is commonly used in laboratories to produce a flame for heating, sterilizing, or combustion purposes. It operates by mixing gas with air and igniting the mixture to produce a controlled, focused flame.
Give two reasons why the yellow flame is safer on busen burner?

What colour is barium chloride?
for the most part you really can't tell if it's coloring the flame at all, that is if you're burning it right on a Bunsen burner. if you're lucky it might spark or give the slightest bit of a white flame.
What color does sodium hydroxide give from a flame test?
Sodium hydroxide does not produce a distinct color in a flame test. It is the sodium ions that give a bright, persistent yellow color to the flame.
