Chemistry ERT - ITEM 3 Item 3.1 and 3.2 – Graphs The trend for the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is…

Introduction Global warming or climate change? No one seems to exactly know what is causing sea level rise, and global temperature increase. Climate experts, scientists, and government officials cannot agree on the exact cause. Is it a matter of not knowing what global warming and climate change truly mean? Or is it that global warming is just a myth? According to the United States Environmental protection Agency (EPA), global warming refers to “the recent and ongoing rise in global average…

In page 29-30, Gonzales mentioned an example on how Latina/o are having problems in assimilating into the american melting pot. He stated, “LANGUAGE IS VERY important here.” The context of the memo shows clearly that in referring to “unmeltable ethnics,” Tanton is speaking about Latinos, whom he sees as a group that could never assimilate into the American melting pot because they are racially different from people of Western European heritage.” In my own words, this statements is just saying…

Crystalline and Amorphous Solids  Solids can be divided into two classes: crystalline and amorphous. Crystalline solids have well-defined edges and faces, diffract x-rays, and tend to have sharp melting points. In contrast, amorphous solids have irregular or curved surfaces, do not give well-resolved x-ray diffraction patterns, and melt over a wide range of temperatures. Crystalline solids, or crystals, have distinctive internal structures…

the four sisters to show what other girls who were not American or not caucasian thought what the definition of pretty had to fit. Most of the time, it was blonde hair and blue eyes. This is where America’s great reputation of being this wonderful melting pot of people and the place for all foreigners to go, is wrong. America isn’t the welcoming place everyone thinks it should be. In fact, America is more of a fake welcome. Maybe we’ll solve all your troubles and give you the help you need to…

The American Dream, The milk and honey of America The American Dream is one of the most famous ideas that people have of America before travelling here. Some see it as a land where all of your problems are solved, and where everything goes your way, but it’s not. America is a land where you have the opportunities to make things go your way, with a little hard work. Anything is possible with a little hard work, and the end-goal of the American Dream is to have a better life with your family by…

Cyclodextrins are enzymatically modified starches composed of glycopynanose units which form a ring of either six (α-cyclodextrin), seven (β-cyclodextrin) or eight (γ-cyclodextrins) units. Characteristics of β-cyclodextrins include: • Glucose unit: 07 • Molecular weight: 1135 • Solubility =1.85g/100ml • Cavity diameter = 6.4 Ǻ • Diameter of outer periphery = 15.4 Ǻ • Approx. volume of cavity = 262 (Ǻ)3 Cyclodextrins have a cylindrical shape with central axial cavity and resembles the shape of a…

Pentane and Diethylamine have many similarities, but they also have their differences. Pentane comes from the Greek word pente meaning “five” as the atom is comprised of five carbon atoms as shown in the formula C5H12. Some characteristics of the molecule is that it gives off a gasoline-like odor, generally does not have a color, and is a liquid. Pentane is commonly used in fuels, building construction materials, explosive materials, food packaging, paint, liquid chromatography, and toys just to…

After doing some research, I discovered there is quite a bit more to the Rocky Mountains than high altitudes and pretty mountain views. First, I found the Rocky Mountains may not be here much longer. In The Rocky Mountains' Largest Glaciers Are Melting with Little Fanfare, Storrow talks to outdoor education professor Darran Wells, who has watched the glaciers on the mountains’ faces shrink year after year. Within the next one hundred years, all the ice on the mountains may be completely gone.…

Southommasane describing fond memories of his home town, Carbramatta, a suburb of Sydney which at one point served as the nation’s drug capitol. Southommasane relates a sense of pride of having grown up in a town that represents such a cultural melting pot. The Cabramatta freedom gate currently bears a number of incriptions, all in English, Chinese, Vietnamese and Lao that constitute ideas of freedom and democracy. Today, Cabrammatta serves as a success story of Australian…
