- 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 gas
hole, off the gas immediately.

The closed flame (orange) is only ever used when turning on the bunsen burner or when you are leaving it for any amount of time to insure the safety of your class mates. The open flame (blue) is used at all other times. Please note it can be hard to see the blue flame so it is important that you stay aware and safe as it is often as hot as 700oC.
Lauren sat in front of the piano then played the incipient note of the musical piece.
Note cards in a science fair project are used to organize and present information in a concise and structured manner. They typically contain key points, data, and references that support the project's research and findings. Note cards help the presenter stay organized during the presentation and serve as a guide to ensure all important information is covered.

You can boil mercury from a Bunsen burner. Mercury has a low boiling point of 674 degrees Fahrenheit, making it possible to vaporize it using a Bunsen burner's high heat. However, it's important to note that working with mercury can be hazardous, so proper safety precautions should be taken.
you put your water in the bursen burner then put in on heat the heat should be moderate to avoid vigorous boiling.Alway take note that you do not make the mouth of the bursen burner to face you put it the opposite side and do not lok in side the bursen burner.
When using a Bunsen burner, ensure there is proper ventilation to prevent the build-up of potentially dangerous gases like carbon monoxide. Use appropriate personal protective equipment such as safety goggles to protect your eyes from potential splashes or sparks. Always place the burner on a heat-resistant surface and never leave it unattended when in use. Follow proper lighting and extinguishing procedures to avoid accidents.

The Bunsen burner is such a familiar fixture of chemistry labs that its reputation reaches students even before they enter the classroom. As an icon of science, it permeates popular culture. But where did the Bunsen burner come from? Who invented it? You might hope to chuckle at the absurdly obvious: "why, Bunsen, of course!" But a brief foray into history may be warranted before placing too significant a wager on the "obvious."Robert Bunsen, whose name we associate with the burner, was a 19th-century German chemist of some renown. He worked on explosive organic arsenic compounds--leading to the loss of one eye--and, later, on gases from volcanoes, geysers and blast furnaces. With Kirchoff he contributed to our understanding of the meaning of spectra lines. (He also gained note for not bathing--one woman of polite society remarked that Bunsen was so charming that she would like to kiss him, but she would have to wash him first.) Bunsen invented many bits of laboratory apparatus: the spectroscope, the carbon-pole battery, an ice calorimeter and vapor calorimeter, the thermopile, and the filter pump--but not, as one might imagine, the gas burner that bears his name. Rather, the "Bunsen" burner was developed by Bunsen's laboratory assistant, Peter Desdega. Desdega himself likely borrowed from earlier designs by Aimé Argand and Michael Faraday. So why does Bunsen get the implicit credit? --And why do we know so little about Desdega that we cannot add much to his story?"Bunsen's" burner illustrates an important dimension of science frequently omitted in teaching about science: professional credit. Eponymous laws and labels--whose names reflect their discoverers--appear throughout science: Snell's law of refraction, Gay-Lussac's law of gases, the Hardy-Weinberg model of population genetics, the volt (named for Alexander Volta), etc. The naming of laws for their discoverers seems appropriate for honoring the scientists--and the human names are handy for reminding students that science is done by real persons. But in this system, one person and only one person gets all the credit. Focusing on great individuals can hide the collective nature of science, especially the role of technicians such as Desdega. How do we distribute the credit where appropriate?The great Isaac Newton is frequently quoted for expressing the humbling effect of the collective effort in science: "If I have seen further," he once professed, "it is by standing on the shoulders of giants." Newton's claim, we now know, betrayed a false modesty. Newton's bitter priority dispute with Leibniz over the invention of the calculus, in particular, bears witness to his ambition and obsession with prestige--and his political maneuvers in trying to achieve it. In that case, at least, Newton tried to further his own stature "by standing on the claims of competitors." In similar ways, perhaps, the contributions of technical workers often get buried when we allow theoretical discoveries of the work of their masters to overshadow them. Bunsen's burner--or perhaps the Desdega burner--is a notable example.The story of the Petri dish is an interesting exception--while at the same time underscoring the general pattern of invisible technicians. Julius Richard Petri (1852-1921) worked for the master of "germ theory" in Germany in the late 1800s, Robert Koch (1843-1910; pronounced as a gutteral "coke"). Initially, bacteria were cultured in liquid broth--a practice captured in our famous images of experiments on spontaneous generation. But Koch saw the advantage of growing bacteria on a solid medium instead. By spreading out mixtures of microorganisms on a solid surface, he could separate individual types in isolated colonies. With pure colonies, he could investigate the effects of each bacterium. The method allowed Koch to identify the specific organisms that cause tuberculosis, cholera, diptheria, among many other diseases--and then to develop vaccines.
The Wrap Fat Burner can help with weight loss and body toning by increasing sweat production, which may temporarily reduce water weight. However, it is important to note that any weight loss from using the Wrap Fat Burner is likely to be temporary and may not lead to long-term fat loss. It is always best to combine its use with a healthy diet and regular exercise for sustainable results.

Since you need the key points to study for your test, the correct answer would be "capturing key points in short phrases."
Yes, using the root note (tonic note) of the scale and its 3rd and 5th note of the scale.
Some effective strategies for note-taking during lectures include actively listening to the speaker, using abbreviations and symbols, organizing notes in a structured format, and reviewing and summarizing key points after the lecture.
Invariants are points that remain the same under certain transformations. You could plug the points into your transformation and note that what does in is the same as what comes out. The details depend on the transformation.
