In The Disappearing Spoon, Sam Kean explains chemistry broadly yet detailed through interesting and thrilling stories. He talks about the elements on the periodic table and how the table came into existence and why it is arranged the way it is. He also looks deeply into the history and concepts of some interesting elements. In chapter 15 called “An Element of Madness,” he goes into an explanation about selenium, manganese, palladium, barium, and unununium. Pathological science is considered…

Global Warming happens when the Earths surface temperature increases due to the greenhouse gases like carbon dioxide have on the ozone layer. These emissions come from the burning of fossil fuels, such as gasoline from cars, or deforestation. This process traps unwanted heat that would otherwise leave the earth, causing a rise in temperature. Global Warming can affect the temperature and weather of the earth and cause many devastating consequences all around the world. The most common greenhouse…

Content Stoichiometry is the relationship of the masses of the reactants and products in a chemical reaction. For a given mass of a substance in a reaction, the mass of any other substance in the reaction can be obtained using the coefficients of the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that…

Explaining Evolution Evolution has always been a relevant topic, whether being explained in learning environments or thoroughly investigated by scientists, why is it so important? Evolution tells the story of how humans, as well as other species, came to be. The articles “12 Examples of Evolution Today” by Erin Brodwin and “A Possible Break in One of Evolution’s Biggest Mysteries” by Peter Brannen are both compelling with the information they provide, and contain insights into the world of…

Ecosystems dependent on sunlight would experience the most adverse effects of global ice cover (DUJS, 2010). This statement is supported by evidence that carbon-isotope ratios from this period are similar to those found in the Earth’s mantle, indicating that photosynthesis was non-existent, and most forms of eukaryotic life were destroyed. However, microfossils have been found that date back to this time, of both…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

Fuoco 1 Cole Fuoco Mrs. Bedell English 10H 10 January 2016 Nuclear Fusion: The Energy Solution It seems like science fiction saying that a city like San Francisco can achieve all of its power needs for a year with only a couple hundred gallons of water, but it true with the incredible power of nuclear fusion. As humans in our ongoing society we are always striving to save a pretty penny, embrace efficiency, and preserve the planet from our harmful pollution. However, it seems as if the human…

Nuclear power is the future of the planet. Using nuclear fission — a chemical reaction that splits the atom of a radioactive isotope — huge amounts of energy can be created. By utilizing the electricity that can be created from the energy released, no one in the world would be deprived of energy. Despite anti-nuclear views that technology is unprepared for natural disasters near nuclear plants, nuclear energy is the solution for the United Sates due to its environmental, economic and…

An atomic can put a stop to a busy city in no time, and the effects are like no other. Most countries never think that anything bad will happen to them. That’s what Japan thought. On August 6, 1945 the United States sent an Air Force Airman to drop an atomic bomb on the city of Hiroshima. Japan and the city of Hiroshima had no idea that it was coming. Then three days later they sent another Airman dropped another bomb on the city Nagasaki. The names were “Little Boy” and “Fat Man.” Little Boy…

SYMMETRY WRITING EXERCISE PARAGRAPH I FePO4 is a type of -quartz, and when the temperature is relatively low, FePO4 still has the tetrahedral structure as seen in Figure 1. The Fe-O-P bridging angles are more similar between the FePO4 and -quartz. Change in the cell parameters become more significant between temperatures of 294K and 1073K, and it slowly acquires an octahedral structure as the temperature increases. When temperature reaches 980K, the compound transitions and the tilt angles…
