Why should a lit Bunsen burner never be left unattended?
It is dangerous as other people may just place their hand or other objects over the Bunsen burner causing injuries or burns, especially if it is a non-luminous flame which makes it difficult to tell that the burner is actually lit. You should always switch off the Bunsen burner before leaving to prevent injuries to others and yourself.
one way to reduce risk when using bunsen burner?

Where do carbon atoms come from in a Bunsen burner?
Carbon particles are created by incomplete combustion of the methane gas. The balance chemical formula for the combustion taking place is as follows: CH4(g) + 2O2(g) ---> 2H2O (g) + CO2(g)
What is the correct way to get salt from a mixture of sand and salt?
If you mean seperate: Use a bunsen burner, a tripod, and a beaker. Place the beaker onto the tripod which should be on top of the bunsen burner. Pour the salt/sand water into the beaker and turn the bunsen burner onto the safety flame. Then put the beaker on the tripod, and wait for the water to evaporate.
How can you minimise risks when using a Bunsen burner?
You can place a wire gauze on top of it and keep a safe distance away form the bunsen burner. Try not to perform anyexperiments while sitting down- it is safer while standing.

How does cold water turn in to hot water?
Heat it. Place a 300ml sample of the cold water in a 500ml beaker and place the beaker on a retort stand about six inches above a standard laboratory Bunsen burner. Turn on the gas and ignite the Bunsen burner. Allow the flame to heat the water for several minutes. When small bubbles begin to form in the water, shut off the Bunsen burner and measure the temperature.
What will happen if you place a flammable substance near a Bunsen burner?
If placed close enough, the flammable substance will burst into flames.
Does combustion occur at the inner cone or the outer cone?
Of a Bunsen Burner flame? Combustion takes place in all parts of the flame.
What is an alcohol lamp?
an alcohol lamp is not better than the Bunsen burner, which can make a flame more higher and stronger.. Because alcohol lamp is used to flame and can burn the environment arround you. Bunser burner is more unique than the alcohol lamp. This alcohol lamp is very dangerous when not use properly. When an alcohol lamp is lighting or it flames, use the cover to prevent it and make the flame be gone for an instant without harming yourself or the objects around you cannot be destroyed.>>>>m.j (14)use to contain a chemical in a cylinder flask.d q alam kung tama to? haha pki improve nalang po :)m.j (14)

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.

Safety proceedures using the Bunsen burner?
Step one: Place the Bunsen burner on a heat proof mat Step two: Check that the rubber tubing is connected properly to the Bunsen burner and the gas tap. step 3: ensure that the air hole is closed Step 4: Light the math Step 5: Open the gas tap Step 6: Hold the burning math over the barrel. Make sure your hand is not in the passage of the flame.
