Noble gas

Throughout history, humans have been overcome by cursitory to figure out the way our universe works. In the past hundreds of years, there have been numerous discoveries that revolutionize modern civilization and the way humans have thought about Earth. One of the most significant discoveries that humanity has found was the fact that everything is made up of elements. The Noble Gases in particular, set the precedent for what all other elements strive to become. Every element in the periodic table bonds to other elements in order to have eight valence electrons, just as the Noble Gases. This “Octet” rule governs modern chemistry and all the laws of the universe. In 1868, a scientist named Pierre Jansen discovered something very out of the ordinary.…

element on the periodic table. It is a light yellow gas and is most commonly known for helping your teeth. I choiced this element because it has the highest electronegativity. But what other traits does fluorine have? Read my ABC book and find out. A is for… Atomic number The atomic number of fluorine is 9. The most common isotope of fluorine is 19F and 18F. Fluorine is more stable in when it has 10 neutrons. Fluorine is a halogen and is placed on the right near the noble gas…

The gas vents on the circular tread face are nearly aligned with the pre-heating or curing mold support gas vents. Since the pre-heat and curing mold as many parts the space between parts are part of the vents. There are detached block on the outside circumference circular tread face. There is a plug in the circular tread face that is held at the outside circumference of the circular tread face and extend to the inside of the gas vent in circular tread face. The plug extends or retreats…

Greeks. Ajax’s reputation sprung from his own successes, giving him a title that warrants more honor than the nobility of the Greeks who inherited their honor. While Ajax acted on behalf of the welfare of others, members of Agamemnon’s “noble” family allowed themselves to let ego rule their actions. Teucer recounts how, mad with jealousy, Agamemnon’s father turned Agamemnon’s…

Ice skating is a recreational activity that can also be a part of high level Olympic competition. It seems natural when watching someone on the ice gliding so effortlessly, but why is this possible? They are gliding on a solid surface after all. When thinking about solids, slippery is probably not a common word to associate with. However, in the case of ice this happens to be true. Looking at the properties of states of matter, properties of water, and experiments of water and ice, there is…

Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…

If a compound is an electrolyte it conducts electricity by breaking down into ions when dissolved into a solution. A non-electrolyte compound does not dissociate in solution. A non-electrolyte compound cannot conduct electricity because it dissolves in solution as molecules instead of ions. Colligative properties are properties of a solution that depend on the amount of solute dissolved, and not dependent on the identity of the solute. The colligative properties studied in this current…

Theoretical analysis for HPHX's performance by using dimension analysis theory. Assumptions Steady operation conditions exist. The surface temperature of the condenser section is equal to the temperature of Refrigerant R-22. Properties The exit temperature of air, and thus the mean temperature, is not known. We evaluate the air properties at the assumed mean temperature of 42OC (will be checked later) and 1 atm as following: K= 0.02722 (W/m.K) …

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

special, and mysterious. Above all, scientists are willing to put their all attentions to study this unknown atmosphere of Titan. This is also a same way that our groups plan to make some missions and built a spacecraft with plenty of instruments, which can send exactly data back to Earth. Hopefully, each instrument really works each other and helps us to reveal mysterious veiling of Titan. Before we introduce the mission, we would like to share much basic knowledge about Titan’s atmosphere…
