Why should a lit Bunsen burner never be near alcohol?
no
When you boil water the water near the stove burner becomes less what?
Becomes less dense
What mixes air and gas in a gas fired furnace?
The adjustable air inlet at the end of each of the burner tubes near the fuel nozzle.
How can you convert ethanoic acid into methane?
The simplest way would be to make the sodium salt by reacting it with NaOH. Then evaporate it to near dryness and continue heating it with a bunsen burner or similar heat source. The decarboxylation will produce methane. This is hazardous because the methane will catch fire with the flame or any spark so a gas collection apparatus of some sort must be used. Another method would be to run the electrolysis of the sodium acetate reaction. Methane would be produced at the anode but would be contaminated with CO2 and some ethane. This method is known as the Kolbe electrolysis and is pretty slow.
Why shold avoid wearing shorts or skirts while working with chemicals and with glassware?
It is to prevent a burn or cut if your legs are bare and you (or someone) spills or drops chemicals or broken glass on you or near you.

What is the hottest part of an Bunsen burner?
Near the tip of a blue flame is the hottest.
Why did Robert Bunsen create the Bunsen burner?
A man named Michael Faraday created and invented the Bunsen Burner, Robert Bunsen improved it by making the flame cleaner, hotter and non luminous. The Bunsen Burner was named after him, but that does not mean he made it.
Why is it important to turn off the Bunsen burner when heating enthanol?
It is important to turn off a Bunsen burner near ethanol because it is highly flammable and could ignite if it comes into contact with an open flame.
What causes a Bunsen burner to make noise?
If you let hydrogen gas near the flame it will pop. The way we got hydrogen gas is by adding hydrochloric acid to magnesium powder and putting our thumb over the top of the test tube trapping the hydrogen gas then releasing it near the flame of the Bunsen burner.
What will happen if you place a flammable substance near a Bunsen burner?
If placed close enough, the flammable substance will burst into flames.
Can you Light a Bunsen burner by turning the gas and oxygen on to full volume?
No. You can not light a Bunsen Burner by turning on gas and oxygen. It takes a spark. (Actually, it takes a certain temperature to get the reaction started. The spark simply brings the material extremely near the spark up to that temperature.)
How do you be safe using a Bunsen burner?
how to be safe using a Bunsen Burner:1. never leave the flame unattended... especially when on the blue flame.2. always wear safety glasses.3. don't heat up anything metal because they will get very hot.4. don't let young children near the Bunsen burner when it's on.5. always have someone watch it.6. turn the gas off immediately when the flame goes out.
How does adjusting the barrel on the Bunsen burner affects the flame?
The bottom of a Bunsen burner contains holes that allow air flow. When there is no air flow, the temperature of the flame will be hotter. With the holes wide open, the flame will not be as hot.
What should you never dispense of near an open flame?
the iron ring, the wire mesh over the ring, the beaker or whatever else was being heated. There are special tongs for most types of glassware or porcelain objects that are heated over a Bunsen burner.
What is the function of the burner tube?
A burner tube is a metallic tube with two opposite air holes near its lower end.it is screwed to the nipple and carries the air regulator
