Survey of the Sciences Week 2 Assignment 2 – Lab 2.1.1 – States of Matter Date of assignment: 12/18/2013 Date turned in: 01/15/2014 Liquid at over 650K | Liquid under 650K | The molecules appear to be faster and more spread apart | Molecules are even faster, mostly touching and mostly compact | Gas at over 1540K | Gas at under 300K | Faster and mostly apart and randomly touching | Slower, more clustered and in ring shapes and mostly touching with less space apart | Solid at 350 – 360K and over 600K | Solid at under 10K | Moving from one position to another at accelerated pace but mostly touching at an even faster rate and mostly spread apart | Less movement, but still clustered and connected in ring forms | Solid is at 157K and appears to be moving slower and less close but compact in rings. Liquid is at 328K and appears to be closely bonded but moving around much faster. Gas is at 809K and appears to be moving much faster and occupying more space than solid and liquid. But when the temperature is reduced to about 97K the rate of movement decreases and the molecules get more clustered and compact, the reaction in liquid is almost the same as gas when the temperature is reduced to the same 97K. The reaction in solid liquid and gas stages of water are almost constant at a reduced temperature of 97K. Only the solid state resembles itself in heated and cooled stages. The others have different resemblance. In...

Mustafa Lab Due Date: 23/2/2016 Overview Enron, a corporation headquartered in Houston, operated one of the largest natural gas transmission networks in North America, totaling over 36,000 miles, in addition to being the largest marketer of natural gas and electricity in the United States. Enron managed the world's largest portfolio of natural gas risk management contracts and pioneered innovative trading products. The company was on Fortune's "Most Innovative" in the United States listing for several years running and reached 7 on the Fortune 500 list in 2000. Its bankruptcy in December 2001 was the largest such filing in United States history. The name Enron became synonymous with corporate greed and corruption, and its demise cost investors and employees over $70 billion in lost capitalization and retirement benefits. Enron shows us what a company and its leadership are capable of, when they are obsessed with making profits at any cost. One of Enron's lasting effects was the creation of the Sarbanes-Oxley Act of 2002, which tightened disclosure and increased the penalties for financial manipulation. Second, the Financial Accounting Standards Board (FASB) substantially raised...

...clues of a crime scene. Each clue adds up to the story of something terrible. A crime has taken place, and law enforcement is on the scene. Whether it is a detective, county Sheriff or the FBI, the investigators will rely on their forensic teams to link all the pieces of the puzzle that don’t quite fit yet. A Forensic Chemist can make them fit by scientifically analyzing the evidence. Chemistry, biology, materials science, and genetics to analyze clue found at the scene of the crime, on the victims or in the bodies of the bad guys. Forensic Chemists go into a case with many unknow pieces of the crime scene they need to analyze to determine the nature of each sample. Most Forensic Chemists work in a lab. It is rare for private labs to do this kind of work so most of the time these labs are associated with Local, State, or Federal law enforcement agencies. From local Medical Examiner’s labs to state of the art FBI labs, Forensics Chemists often provide the strongest evidence in court against the defendants. They have many different types of test and methods they use to figure out what the samples mean. Each crime scene brings new types of clues and samples so a Forensic Chemist must always be thinking of ways to analyze the evidence. Some of the more common test for optical testing, X-ray spectroscopy, UV, and infrared. For separations analyses, HPLC, gas chromatography and thin-layer chromatography. In a typical day a Forensic Chemists could use as many different...

...Lab Report 2 – Titration CHEM1903 – Chemistry 1A (SSP) Michael West (305159240) 1. Experiment 2.2 – Titrimetric determination of the molecular mass of an organic acid Method An unknown organic acid was supplied in solid form. The acid was known to be diprotic and had the reference number 19. Using an analytical balance, 1.5397 g of the acid were weighed out, and made up with deionised water into 250 mL of solution. 25 mL of the acid solution was added to a conical flask with phenolphthalein indicator and titrated against standardized 0.0983 M NaOH solution. Three titrations were performed and the results averaged. The molar mass of the acid was then calculated and compared to a list of given possibilities. Results and Calculations The three titres were 26.30 mL, 26.50 mL and 26.30 mL. The mean titre volume was hence 26.37 mL. The number of moles of NaOH was thus moles. Because the acid was diprotic, reaction stoichiometry dictates that there was one mole of acid for every two moles of NaOH. Accordingly, in 25 mL of the acid solution, there were moles of acid. The molar mass of the acid is then g⋅mol-1. This matches most closely with succinic acid, for which the given molar mass was 118.1 g⋅mol-1. Although this represents a 0.6% discrepancy, the error is small enough to identify the acid as succinic acid with a high degree of certainty, given the possibilities listed. 2.

...that of addictive narcotics whether physiologically addictive and narcotic or not 2: something that soothes, relieves, or lulls”. The government has used science to come up with a list of narcotics and classified them based on several factors and this paper is intended to cover those factors as well as how the law uses forensics to find the evidence needed to proceed within a court of law. One of the first things a court of law has to use is the knowledge of a drugs ability to cause dependency. This means that a person cannot function in a normal manner without the use of the drug and to go without the drug causing withdrawal symptoms. The government also uses information to understand the pharmacological effects of drug based on science as well as other scientific information about each drug. The government also keeps records of whether certain drugs cause a physical dependency or mental dependency or both as well as information concerning each drug with its history, patterns of abuse as well as what the risk is to the health of the public. Information also concerning other drugs or substances used that may enhance a drugs performance (Justia US Law, Indiana Code 2010). Narcotic is the term used by both many states and the federal government for drugs that are both...

...Lab Research Report 1: Procedures in the Physical Sciences Robert Hugee Professor Brian McCann SCI110024VA016-1134-001: Introduction To Physical Science April 25, 2013 One of the underlying challenges in astronomy measurement is the determination of precise distances. Without a knowledge of its distance, the size of an observed object in space would remain nothing more than an angular diameter, and the brightness of a star could not be converted into its true radiated power, or luminosity .astronomy. (2013). Direct measurement of the wavefunction had also long been deemed impossible because of the key tenet of the uncertainty principle. University of Rochester (2013, March 3). Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light. ScienceDaily. Large-scale surveying & mapping problems are also key challenges in making direct Measurements in astronomy. Pogge R.(2006) One of the indirect forms that the scientists have used is to resort to GEOMETRY to find the Distance. Parallax is one of the indirect methods where astronomers can measure the position of a nearby star very carefully with respect to more distant stars behind it, then measuring those distances again six months later when the Earth is on the opposite side of its orbit. Allen J.,Boyd P. (1997,April 15) The limitation of parallax is that it just gives distances to stars tp up to a few thousand light Years and beyond those...
