The hole in the center of the Bunsen burner flame is caused by air being drawn into the flame and mixing with the gas, promoting efficient combustion. This produces a hot, blue inner flame that is ideal for heating purposes. The outer, cooler part of the flame is yellow due to incomplete combustion.
What else can I help you with?
When Bunsen gauze gets hot what do you see?
When Bunsen gauze gets hot, you generally see the metal mesh glowing red or even white hot, emitting heat and light. This indicates that the gauze is reaching high temperatures, which is important for conducting certain laboratory experiments properly.
Is the following sentence true o false?
I'm here to help! Please provide the sentence you would like me to assess for truth or falsehood.
Weight of the body at the center of the earth?
Here's a nice general rule to ponder: At the center of mass of any planet ... whichis the center of the planet if its mass is distributed uniformly and symmetrically ...the weight of any object due to gravitational attraction is zero.
What is the maximum temperature a fire can reach?
Thomething about 1200 and 1500 degree, its a very conced degree here in Celcius. If you see a fire from gas with it´s blue flame, it has exactly the temperature from about, if you see a yellow flame it is also exactly one spezial degree. That is that astonishing it never various . . . and does not come over 2000
Why the center of pressure is below the center of gravity for an inclined surface?
I'm going to guess it's for easier guidance. If center of pressure were above CG, you'd blast your rocket so that's out, we're not pulling here, we're pushing. If CP is below but too close to CG, you would have a balancing issue. Try to balance a tall object such as a broom on your hand. It's much easier to do than balancing a short object such as a pen. Easier to correct and stay under CG, with more distance.
What is a regular flame on a Bunsen burner?
I am not 100% sure what you are asking here however I will do my best to answer it. The gas that is used in most bunsen burners is methane (natural gas). This is not true for all labs as I have heard of labs using town gas (which is made from distillation of coal). A regular flame on a bunsen is orange this the coolest flame (300°C) and is rarely used. more common will be the blue flame which closer to 700°C. When leaving the bunsen for any length of time the orange flame should be left on as it is easy to observe and insures the safety of your fellow class mates.

What are the temperatures of the Bunsen burner flame zones?
A Bunsen burner flame consists of an inner cone and an inner cone. In the inner cone, no combustion is occurring and the inner cone consists of a mix of air (which has been introduced through the vents in the bottom of the barrel) and gas. In the outer cone, combustion is occurring. Hence a Bunsen burner flame is "hollow;" there is no flame in the inner cone. Because air, containing oxygen, is present in the inner cone, it is called the "oxidizing zone." A piece of red hot copper held inside the inner cone will oxidize, being covered with a layer of black copper oxide.
What can be used for heating small amounts of liquid?
a) Here are some examples of apparatuses that may be used for heating liquids: Bunsen burner b) Alcohol lamp c) Beaker d) Test tube e) Tripod f) Wire gauze g) Iron stand h) Iron clamp
Q: Why do you have to turn off the Bunsen burner before you place the test tube containing methylated spirits in the beaker of water?
It seems like there might be a misunderstanding in your question. It's important to clarify that a Bunsen burner is a piece of laboratory equipment used for heating, and methylated spirits (commonly known as denatured alcohol) is a type of alcohol used for various purposes, such as fuel or disinfectant. If you are heating a test tube containing methylated spirits over a Bunsen burner and then placing it in a beaker of water, here are some reasons why you might want to turn off the Bunsen burner before doing so: Safety: Turning off the Bunsen burner reduces the risk of an open flame near flammable materials like alcohol, which can catch fire easily. By turning off the burner, you eliminate this risk. Control of the heating process: Once the test tube is heated to the desired temperature, turning off the Bunsen burner allows you to control the heat transfer to the test tube and its contents. This can prevent overheating and potential hazards. Preventing accidents: If the Bunsen burner is left on while placing the hot test tube in a beaker of water, it could potentially cause the water to splash or boil violently, leading to accidents or injuries. Turning off the burner eliminates this risk It's important to follow proper laboratory safety protocols and procedures to ensure the safety of yourself and others in the lab. Always be cautious when handling flammable materials and hot equipment to prevent accidents and injuries.

Why does sodium carbonate not decompose when using a Bunsen burner?
because its a single, stable element. its not like copper carbonate, which is a compound of more that one element; here these elements can break apart
What are the points to note in using the Bunsen burner?
- Never leave the gas on when the flame is out- never put anything you don't intend to heat- ensure the tube is arranged properly as if it is turning here and there, the gas might just be stucked somewhere and there will not be any fire burning- never touch the collar(the neck) as it is very hot and when it strikes back at the gashole, off the gas immediately.
Why does sodium carbonate not decompose when heated using a Bunsen burner?
Sodium carbonate does decompose when heated, it undergoes thermal decomposition to form sodium oxide (Na2O), carbon dioxide (CO2), and water (H2O). However, the decomposition of sodium carbonate is not easily noticeable when using a Bunsen burner as the high temperature and rapid combustion of the gas can mask the decomposition reaction.
What are the different zones of candle flame?
The candle flame has 4 zones from innermost to outermost: 1)Blue zone: It is near the base of the flame. Here the fresh air rapidly mixes with was vapour formed from the molten wax.A part of wax vapour completely burns and gives rise to blue flame. 2)Dark inner zone: This part consists of unburnt wax vapour given off by molten wax.It is the coldest part of the flame It is dark because of of decomposed carbon particles. 3) Luminous zone: In this zone partial combustion takes place with liberation of a lot of heat. This zone is hotter than the dark inner zone. 4) Non luminous zone:It is a zone were complete combustion takes placeIt is hottest part of the flame and is hardly visible.
What are synonyms for flare?
Here's a few: erupt, flame, flash, irrupt,
Do you provide blue ray burner?
Blue ray burner are an awesome way to converted your DVD to something even better. Wal-Mart, Target and Best Buy are some of the place around here that provide the blue ray burner with a great price selections.
What are the products of a Bunsen flame?
methane gas combines with the oxygen in the air in a combustion reaction. the only products of combustion are carbon dioxide and water (and energy) To be more specific - Hydrocarbon methane CH4 and Oxygen 2O2 and the combustion of the gas yields Carbon dioxide CO2 and water H2O CH4(g) + 2O2 ----> CO2(g) + 2H2O(g)
