Glass (Borosilicate)
Introduction
Noble gases are the most commonly known inert elements. However, to have a solid material that is inert as well would be highly beneficial to many industries — chemical, medicinal, and pharmaceutical (Glass Alliance Europe, n.d.). Especially in the chemistry industry, where scientists must store and examine countless chemicals, such material is crucial, and if non-existent, would make dealing with chemicals much more difficult. Thus, scientists incorporated glass (specifically borosilicate glass) into their laboratories — a neutralized and transparent material in which most substances contained within would not typically have a tendency to react with the structure of. It is also resistant to heat and chemicals,

In order to break apart bonds, demands energy levels equivalent to that used when creating it (Indiana University, n.d.). Boron Trioxide, is an intermediate that synthesizes the glass, creating a low coefficient of heat expansion, giving the substance glass its heat resistant property and attributes to its mechanical strength (University of Delaware, n.d.)(Glass Alliance Europe, 2012). Na2O is added to the melting mix of silica and aluminum (which reduces energy needed) to create the highly durable glass, providing better chemical stability.
The prevalent molecule bond in this list is SiO2, silicon-oxygen, a bond that has a high enthalpy of formation (contributes to the chemical stability of glass). It would require a possible bond stabler than silicon-oxygen to interfere with the compound. The majority of substances existing would not be altered when stored within the inert material, thus it is used in the laboratory.

The primary goal of this laboratory project was to identify an unknown compound and determine its chemical and physical properties. First the appearance, odor, solubility, and conductivity of the compound were observed and measured so that they could be compared to those of known compounds. Then the cation present in the compound was identified using the flame test. The identity of the anion present in the compound was deduced through a series of chemical tests (Cooper, 2009).
American businesswoman Carly Fiorina once concluded, “If a decision-making process is flawed and dysfunctional, decisions will go awry.” In the critically acclaimed memoir The Glass Castle, Jeannette Walls pilots a turbulent excursion through the bottleneck of her childhood and dysfunctionality and flawed decision-making is all too common. Throughout this memoir the reader learns of the the appearances and disappearances of stability and functionality, discovers the theme of fantasy vs. reality, and determines how and why the familial dynamics of the Walls alter through the duration of the memoir. The reasons for the instability of the family are evident.
GLASS written by ellen hopkins intermenes the real life struggles that teenagers face everyday, from love to drugs to destructive relationships. Ellen really hits home showing the life of a once 4.0 honors student Kristina; whose life easily got turned upside down from one toxic summer at her fathers that will show the darkest side possible of life. An estimated 12 percent of children in the United States live with a parent who is dependent on or abuses alcohol or other drugs. Based on data from 2002 through 2007, it was to be reported that 8.3 million children under the age of 18 lived with at least one substance-dependent or substance-abusing parent according to Substance Abuse and Mental Health Services Administration (Paragraph 4). The bond between a child and their parents is so pure yet
Did you hear about the two little boys who found themselves in a modern art gallery by mistake? "Quick," said one, "Run! Before they say we did it!" Although this may be a hilarious slap your knee joke, I believe this depicts how society feels about modern art. As a popular saying goes “’Modern art’ is produced by incompetents, sold by charlatans, and bought by ignoramuses!” Why such the skepticism towards current art? Why do art historians and renowned scholars set new art aside in favor of a Monet or Rembrandt? Is the importance of modern art so infinitesimal that it is reduced to child’s play? Or, better yet, is contemporary art worthy enough to be art?
In September 1959 DiVita asked 2nd Lt. Richard Sturzebecher if he knew of a way to produce a strong glass fiber that would be capable of carrying a light signal. Sturzebecher had melted 3 triaxil glass systems together for his senior exam at Alfred University. In his exam, Sturzebecher had used SiO2, a glass powder produced by Corning. Whenever he had tried to look at the substance through a microscope he would end up with headache. Sturzebecher realized that these headaches came from the high amounts of white light produced from the microscopes light that was reflected through the eyepiece via the SiO2. SiO2 would be an ideal substance for transmitting strong light signals if it could be developed into a strong fibre.
When people are under the influence of alcohol, using glasses in bars wouldn’t be a good idea, it would actually be pretty dangerous. After what happened to their client the bar decided to switch from glasses and glass bottles to polymer ones, which don’t shatter, they are so strong that they are bulletproof. “Doctors want drinks to be served in plastic to stop 'glassing'
A very important compound is dialuminum oxide Al2O3. The structure of dialuminum oxide is sometimes hexagonal. The structure is .It is one of the hardest substances known.

The explicit presentation of the mathematics involved in the Arrhenius equation (Michels, Tsong, and Smith 1983) rendered the parameters involved in glass hydration understandable. However, the actual implementation of the physical processes described in the mathematical equations into a model replicating the natural environment is a complicated problem hard to solve (Stevenson 1998).
The primary goal of this experiment was to determine which types of glassware are the most accurate and precise in measuring substances. Another goal of this experiment was to help familiarize ourselves with the different types of glassware, and how we should handle the laboratory equipment. The accuracy and precision of a particular type of glassware is important because it allows for accurate measurements when performing different experiments. It also allows us to differentiate between glassware that is better for containing substances versus glassware that can deliver substances more accurately. In order to measure the accuracy and precision of the different types of glassware, we first chose seven different types of glassware. The general
Today safety glass, which will not splinter when exposed to shock, is in windshields for cars. Essential as it is, safety glass was the result of a clumsy mistake. In 1903, Edouard Benedictus, a French scientist inadvertently knocked a glass flask to the floor when fetching reagents. He heard the glass shatter, but later, he saw the broken pieces of the flask still hung together, more or less in their original contour. Then he learned that the flask had recently held a solution of cellulose nitrate, a liquid plastic, which had evaporated, apparently depositing a thin coating of plastic on the flask’s interior. He experimented with coating glass with liquid plastic, then shattering it and it was not broken. When Benedictus read that most of the drivers seriously injured had been cut by shattered glass windshields, he knew that his unique glass could save lives. Unfortunately, automakers were uninterested in the costly safety glass for windshields. It was not until the outbreak of World War I that safety glass found its first application: as the lenses for gas masks. After automobile executives examined the proven performance of the new glass under the extreme conditions of battle, safety glass’s major application became car windshields. It was very dangerous when something hit your car, the glass was broken and as a result, you would be sore and even dead. But with this unbreakable glass, now you don’t have to worry about this because nothing can touch you from the outside.
chains instead of hydrogen atoms. Cross-linking is another way in which the polymer can be made stronger. This involves ultraviolet radiation that bombards the polymer with electrons and formulates bonds between the molecular chains of the polymers. This is like linear polyethylene but different in that it is more impact resistant, and it has a much higher density. This allows it to be stored or be used with different chemicals that would normally cause the polymer to desolve.3 This can start to become a problem because as the polymer continues to become chemically enhanced. So the ways of dissolving and recycling the polymer become more difficult.
In order to learn how glass fractures, we must first learn the composition of glass and the different types of glass. Glass is a hard, brittle, amorphous substance composed of sand (silicon oxides) mixed with various metal oxides. When sand is mixed with other metal oxides, melted at high temperatures, and then cooled to a rigid condition without crystallization, the product is glass (Saferstein, 2010). Glass can come in many different forms all of which can range from very brittle glass to bullet proof glass; the stronger the glass, the more ingredients are required and the more complex the process is.
Metalloids can be applied in almost all aspects of life. From being used in gum and toys to technology and spacecraft, metalloids are very useful. For example, Silicon can be used in electrical insulators, fabric softeners, hair sprays, hand creams, furniture, polishes, paints, adhesives, and gum. While Arsenic is used for bronzing, the hardening of lead in shotgun shells, and as a dopant, because metalloids are semiconductive, Antimony could be used in making bells, tools, printing presses, batteries, alloys, bullets, and cable sheathing. Furthermore, Tellurium is used to build electronics and make metals easier to cut. Tellurium is also used in coloring glass, porcelain, enamel, and ceramics. Lastly, Germanium is used in fluorescent lamps, infrared spectroscopes, and infrared detectors. Together, metalloids have many applications that can be used to create and upgrade certain
Fiber optics, in the world of technology, is used to carry voice, data, and video inside these strands of glass. Optical fiber for telecommunications consists of three components: core, cladding and coating. The core is the central region of an optical fiber through which light is transmitted. The core and cladding are manufactured together as a single piece of glass and cannot be separated from one another. The third section is the outer protective coating. This coating is typically an ultraviolet (UV) light-cured acrylic applied during t...
Since the days of Aristotle, all substances have been classified into one of three physical states. A substance having a fixed volume and shape is a solid. A substance, which has a fixed volume but not a fixed shape, is a liquid; liquids assume the shape of their container but do not necessarily fill it. A substance having neither a fixed shape nor a fixed volume is a gas; gases assume both the shape and the volume of their container. The structures of gases, and their behavior, are simpler than the structures and behavior of the two condensed phases, the solids and the liquids
