Alexander Kollmann 9E D Assessment - Sulfuric Acid Mr. Curran 09.03.2015 Introduction Sulfuric Acid, also known as Oil of Vitriol to medieval European alchemists, is a colourless, greasy, dence and also corrosive liquid, that has the chemical formula of H₂SO₄. It is arguably one of the most important chemicals, that can be used for important things that benefit society to many extents. It can be prepared industrially, with the reaction of water and sulfur trioxide, which can be made by...
Analysis of the metal silver's chemistry Hello my fellow readers. My name is Silver. My name comes from the Anglo-Saxon word of Siolfur. Some people call me Ag for short (Ag stands argentum.) I am a white shinny metal. Since I am a white shinny metal argentum is the Latin word for white and shinning. I live in the periodic table of elements and my address is 47. I usually weigh 107.868. I am solid at room temperature. Copper and gold are my good friends and they make me strong and help me to...
Science, DNA Testing and Modern Crime Solving After a long day at work, you decide to crash on the couch and watch a little television. After flipping through the channels, you notice the impressive line-up of police, courtroom, and medical dramas. Finally, you settle upon an episode of Law and Order. Tonight’s episode is about a young girl who was raped and murdered. In the end, extensive D.N.A. testing reveals the true killer, and the case is solved. Like many other prime time...
Introduction Chapter 3, “Capacitance,” contains laboratory experiments designed to explore the relationship between voltage and the amount of charge stored in an object. These experiments involve measuring electrical properties of capacitors in series, in parallel, while charging, discharging, and at varying widths between the surfaces. Hands-on experience and resulting data should provide insight into the nature of capacitance. Theory In order to charge an object, a certain...
Necrotizing fasciitis, commonly known as flesh-eating disease or flesh-eating bacteria syndrome, is a rare infection of the deeper layers of skin and subcutaneous tissues, easily spreading across the fascial plane within the subcutaneous tissue. The most consistent feature of Necrotizing Fasciitis was first described in 1952 by Wilson, as necrosis of the subcutaneous tissue and fascia with relative sparing of the underlying muscle. Necrotizing fasciitis progresses quickly, having greater risk...
Does HIV cause AIDS? The AIDS Controversy "Science is nothing but perception" ---Plato--- In the first part of my discussion on the HIV/AIDS controversy, I discussed some of the reasons some people were unwilling to believe that HIV causes AIDS. I did not focus on the scientific community nor did I explain how the science handles data that conflicts with accepted scientific theory. This essay will explore these themes. It will concentrate on the scientific establishment and how it formulates...
H, hydrogen to the He, Helium Lithium, Be, Beryllium Already getting sick of ‘em Next is Boron with a B Then Carbon with a C Man, it’s just so easy when I know that N is Nitrogen Continue with my flow to the O in Oxygen So fresh and so clean Number 9 is F Fluorine Then Ne is Neon I won’t be just a peon Never ever be wrong Know the atoms like I’ve been here the last 7 eons …So anyway, Na is Sodium Look at my flodium, I’m eroding ‘em Straight leaving em In the...
Automobile emissions and their effects on our environment and our health has been a widely debated topic over the last few decades. The automobiles we use today emit large quantities of toxins that deteriorate the quality of air we breathe. Concerns over this phenomenon rose among very few people over half a century ago. Nowadays, concerns for the environment are commonly held, and everyone needs to be aware of the impacts our environment faces. The last century has witnessed a huge growth in...
Artificial Intelligence and the Chaos Theory Recently, the media has spent an increasing amount of broadcast time on new technology. The focus of high-tech media has been aimed at the flurry of advances concerning artificial intelligence (AI). What is artificial intelligence and what is the media talking about? Are these technologies beneficial to our society or mere novelties among business and marketing professionals? Medical facilities, police departments, and manufacturing plants have all...
Reaction Enthalpies and Hess’ Law Introduction: This lab will show us how to first determine enthalpy using a simple calorimeter then apply Hess’ law to determine the change in enthalpy for a third reaction. data: Part1: The Heat Capacity of the Calorimeter Ccal = 135kJ (Very off, so we used 30kJ for the rest of our calculations) [img:732940a099]http://www.collegepimp.com/echeat/lab7.gif[/img:732940a099] Discussion: The purpose of this lab was to learn how to determine...
