What are the two regions in a Bunsen burner?
What are the two regions in a Bunsen burner? The two regions in a Bunsen burner flame are: 1.An outer transparent, dim blue cone. 2.An inner,less transparent, brighter greenish-blue cone. This relatively non luminous,cone shaped flame is a combustion of carbon-hydrogen fuel which is used in a Bunsen burner to provide heat for laboratory purposes.
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
What are the bad Bunsen burner flames?
The yellow flame, containing unburned carbon, is considered as bad.
Can a Bunsen burner create carbon monoxide?
Yes, a Bunsen burner can produce small amounts of carbon monoxide when the combustion is incomplete due to insufficient oxygen supply. It is important to ensure proper ventilation and adequate airflow to prevent the buildup of this potentially harmful gas.
When air hole of the Bunsen burner is closed what is the observation?
When the air valve in closed a yellow luminous flame is observed due to carbon particles from in incomplete combustion.
What dos a Bunsen burner do when the air hole is clos?
When you close the air valve of a Bunsen burner the flame turns yellow due to incomplete combustion and the ignition of carbon particles (soot).
What is deposited on the porcelain dish when put in a bunsen burner with yellow sooty flame?
The yellow sooty flame is a sign of incomplete combustion in the bunsen burner, which produces carbon particles (soot) along with carbon monoxide. When a porcelain dish is placed in the flame, these carbon particles can deposit on its surface, leaving a black residue. This residue is mainly composed of carbon.
Why does porcelain go black when heated over Bunsen burners?
Porcelain will turn black when heated over a Bunsen burner due to carbon deposits from incomplete combustion of the gas. The carbon particles are deposited on the surface of the porcelain, causing it to appear black.
What is the black substancecreatedmade by a yellow Bunsen burner flame?
The black substance created by a yellow Bunsen burner flame is typically soot, which is carbon particles that have not fully combusted in the flame. The yellow color of the flame indicates incomplete combustion, leading to the production of soot as a byproduct.
What happens when methane is burnt in the Bunsen burner?
When methane is burnt in a Bunsen burner, it undergoes combustion with oxygen to produce carbon dioxide and water vapor. This reaction releases heat and light, which is used to provide a hot, blue flame in the Bunsen burner for heating purposes.

Why is a luminous yellow flame on a Bunsen burner often smokey?
A luminous yellow flame on a Bunsen burner indicates incomplete combustion, which can produce soot or smoke. This happens when there is not enough air mixing with the fuel gas, leading to inefficient burning of fuel and the formation of carbon particles that become visible as smoke. Adjusting the air intake on the Bunsen burner can help achieve a cleaner, blue flame with complete combustion.
What does black soot deposited on the porcelain dish consist when it is being at the top of Bunsen burner?
The black soot deposited on the porcelain dish is primarily carbon particles that result from incomplete combustion of the gas in the Bunsen burner. The high temperatures at the top of the flame cause the gas to break down into carbon atoms, which then combine to form soot when they cool and deposit on the dish.
When heated with a Bunsen burner does sodium carbonate decompose?
Yes, when heated with a Bunsen burner, sodium carbonate (Na2CO3) decomposes to form sodium oxide (Na2O) and carbon dioxide (CO2).
Why does carbon get produced when a Bunsen burner is on a safety flame?
The oxygen necessary for burning is not sufficient.
What gasses come from a Bunsen burner?
The Bunsen burner uses natural gas to burn. Methane, CH4. Below is the equation of Bunsen burner combustion. CH4 + 2O2 --> CO2 + 2H2O Methane burns combined with oxygen gas ( with ignition from a flame ) from the air and carbon dioxide and water are the products of this Bunsen burner reaction.
How does a Bunsen burner sterilize the area around it?
A Bunsen burner simply burns everything around it. It oxidises any impurities in the surrounding area, removing particulates such as carbon and changing them into carbon dioxide, these gasses then dissapate away from the area, sterilising the area.
