A Bunsen Burner is more useful because its flame is more controllable , it can reach
a roaring blue flame, and its features such as the collar and the gas controller makes it safer.

What is a burner used for in the lab?
A Bunsen burner has several uses in the lab, the most obvious being its use as a heating element. Bunsen burners can reach a temperature of up to 1000 degrees Celsius, which is hot enough to melt silver. Bunsen burners are also useful for initiating combustion, a common experiment being the burning of table sugar in a test tube to yield carbon dioxide, water and ash. In biochemistry and microbiology labs Bunsen burners are used to sterilize equipment.
Why it is more useful to make ethyl acetate with acetic acid and alcohol rather than using other compounds like ketene alcohol or acetamide alcohol?
because it does not react in acetic acid
What is the role of the mineral acids in the esterification process?
esterification is between an organic carboxylic acid and alcohol but sulphuric acid is required in mechanism which converts the carboxylic acid molecule into a carbonium ion which reacts with alcohol and forms an ester.
What is the use of a Burner oil?
Oil burners are used to burn fragrances or aromas. Especially useful as air fresheners because heat makes for a more penetrating smell. Very good for removing pet odors.
Where was rubbing alcohol invented?
According to someone named Jerry who wrote a household hints book I once had, isopropyl alcohol was invented by scientists at the Standard Oil Company in Linden, NJ in 1920. They were trying to invent useful substances from by-products of gasoline manufacturing. They did a few procedures with propylene gas and out came isopropyl alcohol!
How was a Bunsen burner made?
The Bunsen burner was the result of a building lighting approach that Robert Bunsen was trying to implement in a new laboratory building he was entrusted to design for the University of Heidelberg. The building had a gas supply which was thought to be useful for creating heating and lighting capabilities. The Bunsen burner was to regulate this gas supply for these purposes.
Which fuel is useful for a spirit burner?
alcohol, methelated spirits, ethanol
What are the functions of flames produced by a Bunsen burner?
A Bunsen burner is designed to produce a focused, hot flame in a way that radiates heat up, and not out. This means it is very useful for heating up a small sample of matter (like in a test tube), but for it still to be safe enough to handle in close quarters.

What arethe Uses of clay shield and rubber tubing?
The clay shield and rubber tubing are useful in heating during experiments. The rubber tubing connects the Bunsen burner to the gas outlet. The tubing enables the water to cool as it flows through the condenser during the distillation process.
How is alcohol useful?
Alcohol is useful to cleanse things. Alcohol can kill bacteria. Therefore it is often used in a disinfectant. Most of the time it's 70% alcohol 30% water
Different types of reference materials?
the different materials in a science lab are very useful a few of these materials are a pipette,test tube,bunsen burner,gauze and many more
How is alcohol useful back then?
As an anesthetic and disinfectant? When was "back then?"
What is a depressant drug made by a useful microbe?
alcohol
How does the number of carbon atoms affect the degree of luminosity of the flame produced?
luminous flame is the flame when you have not opened the air hole of your Bunsen burner. it moves around a lot. it looks a bit like the flame you find on candles. only it's a lot bigger. non-luminous flame is the flame when you have opened the air holes of your Bunsen burner. it's really steady, coloured blue only with no orange around it. sometimes though, you'll see small orange flames going up and disappears. ---------------------------------------------- Luminous: emitting light A luminous flame is created from an exothermic reaction (normally oxidisation) between that also emits visible light (EM radiation of wavelength 390[violet light]-750nm[red light]). A non-luminous flame is one that doesn't (EM radiation of wavelength<390nm but >750nm) Basically, if a reaction is making lots of heat (your normal, yellow Bunsen burner flame is at about 700^C) and you can see it, it's luminous. If you can't see it (and the heat is there) then it's non-luminous) [The yellow Bunsen burner flame is from the oxidisation of carbon molecules left over from the methane-oxygen reaction. The blue one is too, it's just happening faster so the wavelength decreases - ask your local physics teacher or put 100nm into Wikipedia search]
What two elements did robert Bunsen discover?
Robert Bunsen was born on the 30th of March 1811 in Gottingen, Germany. Robert was the youngest of four sons, he was one of the most appreciated scientists of his generation. He was a great teacher, dedicated to his students. He liked to work quietly in his laboratory, continuing to improve his science with useful discoveries. He never married. Bunsen started studying in chemistry, and received his university degree at 19 years of age. After graduation, he traveled throughout Europe to study engineering, geology and chemistry. One of his first discoveries was in physiological chemistry when he discovered the iron oxide hydrate as a medicine for arsenic poisoning. Bunsen's discoveries added to his scientific knowledge because he would make mistakes trying to invent or create something new and he would make mistakes and that will help him learn more about what he was trying to create. Robert retired at the age of 78 and was 88 years old when he died on the 16th of August 1899,
