...Unit 1: Unit 1: Scientific Questions: Inquiry and Methods - Discussion What’s in the can? One afternoon, while finishing up your shift as the stock manager at Circus Supermarket, the store manager tells you that he desperately needs some help with an inventory problem. In the back of the store, he shows you an unmarked, unopened tin can and explains that the owners of the store are threatening to fire him and all his staff if they cannot keep track of the items that they sell. There are no inventory records to trace the origin of the can, so he asks you, the stock manager, to help him figure out what is inside. Unit 1: Unit 1: Scientific Questions: Inquiry and Methods - Discussion What’s in the can? My First question would be what type of warehouse was it, in what isle of the warehouse was the can found, what other cans surrounded the can if any. Were any of the cans in the isle similar looking to the one in question, if not what objects or labeling, or postings were found on the shelf surrounding the can in question. What is the shape of the can, is it in the shape of a cylinder, round, or square etc. etc. Even though there are no shipping documents of the origin of the can in question I would ask the manager for whatever shipping documents he has to see if something was missed and maybe trace what records there are and maybe see if this can came through with another shipment. I would ask my staff if they might remember anything though minute that might...

...In the ‘Blue Peter’ interview with JK Rowling, author of the 'Harry Potter' books, the questions that were asked were planned, open and friendly. They seemed planned because when the kids were asking the questions, one of them seemed like they were trying to remember her question word for word. The questions were pretty open because JK Rowling had the freedom to answer the questions with any answer rather than a simple yes or no. Since it was young children, mainly girls, who were asking the questions and because the kids were fans of her books, the questions were friendly. The structure of the interview was so that the kids or interviewers were sitting around the interviewee, JK Rowling. She was sat on a throne-like chair in the middle of the room with all the interviewers around her. There were also a few adults in the room with the kids to help with them. The reason children were used to interview JK Rowling was because they were all fans of the series and were different ages, although they were mainly girls, there were one or two boys there and this was creating a variety of questions within the room. During the interview, when she was asked a question, she gave a mix of long and short answers and she kept eye contact with the child who asked the question. She also made faces when explaining something and used formal Standard English but it a slightly simpler way so the kids can understand. JK Rowling also used a range of short answers and long answers just like the...

...Many chemical reactions are affected by temperature. The chemical reaction in a battery slows down in lower temperature which results in loss of capacity. A battery will deliver 100% of its capacity at 770F and at 200F the battery can only deliver 74% capacity. Excessive heat will contribute greatly to reducing battery life by corroding the positive terminal. Overcharging of the battery is the most common contribution to excessive temperatures and gassing in the battery. Consistent undercharging of a battery will gradually run down the cells and results in one or more cells becoming completely discharged before others. Periodic equalizing charges that return the cells to a normal condition are a good battery maintenance procedure. Overcharging may also cause permanent damage...

...CHEMICAL EQUILIBRIUM Equilibrium occurs when the rate of the forward reaction is equal to the rate of reverse reaction. Concentration of the reactants and the products remain the same. Dynamic equilibrium occurs when the processes do not stop and forward and reverse reactions still continue in both directions at the same rate. A homogeneous reaction is a reaction wherein all the reactants and products are in the same phase e.g. all are gases. A heterogeneous reaction is a reaction wherein all the reactants and products are not in the same phase. If there is no interaction between the system and its surroundings, i.e., a system from which no substances in the reaction can escape, we say it is a closed system. Calculation of the substance amount and concentration at equilibrium We can determine the concentration of the substance by dividing the number of mol of the substance at that stage of the reaction by the volume of the container in dm3, i.e.: c= n/V where c or [ ] = concentration of the substance in mol.dm-3 n = number of mol of the substance V = volume of the container in dm3 It is handy to use a table to determine these values. Example 1 A mixture of 5 mol H2(g) and 6 mol I2(g) are placed in a sealed container of 2 dm3 at a temperature of 4580C. The balanced chemical equation for the reaction is: Equilibrium is reached after a certain time. At equilibrium there is 4mol HI(g) in the container. Calculate the concentrations...

...------------------------------------------------- Abstract The atoms in a compound are held together by a chemical bond. There are two types of chemical bond: ionic and covalent bond. An ionic or electrovalent bond results from the electrostatic attraction between metal and non-metal atoms by the transfer of electrons. _____________________________________________________________________________________ Introduction The atoms in a compound are held together by a chemical bond. There are two types of chemical bond: ionic and covalent bond. An ionic or electrovalent bond results from the electrostatic attraction between metal and non-metal atoms by the transfer of electrons. One example is the formation of bond between a sodium metal atom and a chlorine non-metal atom [1]. In contrast, covalent bond involves the sharing of valence electrons between non-metal atoms. A covalent bond becomes polar when there is unequal sharing of bonding electrons. This happens when the elements involved in the bond has a significant difference in their electronegativity, such as in hydrochloric acid, HCl. Equal distribution of bonding electrons leads to the formation of a non-polar covalent bond. This happens when there is small or no difference in electronegativity between the atoms in a bond. Chlorine gas, Cl2, has a non-polar covalent bond. Electrical conductivity, the flow of electric current, can be used as a basis for determining the type of chemical bond present in a compound. An ionic compound, when dissolved in an...

...The difference between a mixture and a compound is that a mixture is a substance made by mixing other substances together. Most of the time two or more substances that are chemically united and they do not exist in fixed proportions of each other. Unlike a compound a mixture can be physically separated into pure compounds or elements. For example a cake is made up of different substances that are mixed together that are separated. A compound on the other hand is just the opposite of a mixture. A compound has a constant composition with fixed ratio of elements. It can have properties different from its constituents as a new substance is formed when they are chemically combined. The difference is that a compound can only be separated by chemical methods. That is like taking platinum and gold and melting them both down together. You get platinum gold which is a mixture of two elements combined together. 2. Suppose that you have a pure substance. How can you tell whether it is a compound or an element? You can tell the difference because a compound is a mixture of two or more elements. An element on the other hand is a single thing. It is actually divided into pure substances and mixtures. When we have two or more things that are not chemically combined that is called a mixture. They can be divided into homogeneous, like the particles that are throughout milk or heterogeneous, in which we can tell it is mixed like sand and salt. A pure substance on the other hand is when...

...heard about a company named BASF before, I was worried about writing a research paper about it. However, when I visited its website, my worries disappeared, because the website had lots of valuable information that informs me about what they did in the past and what they plan to do in the future. The BASF is a chemical company that was established in 1865 in Germany. The company name, BASF, stands for Badische Anilin- und Soda-Fabrik (Baden Aniline and Soda Factory). The company has more than 140 years of history and has gone through dramatic changes, which has lead to it becoming a universal modern company. According to its website, there are more than 110,000 employees and 385 production sites all over the world, and its goal is to be a “world’s leading chemical company.” The BASF produces various chemical related products, and these are six main product categories: chemicals, plastics, performance products, functional solutions, agricultural solutions and oil & gas. A few of its competitors are Bayer AG, Dow Chemical and TOTAL. Those companies have similar business products as BASF; however, BASF seems to be the only company that does everything, from chemical related to products to oil & gas. Therefore, the BASF is pretty competitive. By doing some research about this company, I was able to find many attractions that would make students want to work for the company. First, it is a world-wide company that one can work in different regions including Europe, North America...

...CHEMICAL BONDS Chemical Bonds I. Introduction Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms called a chemical bond. The two extreme cases of chemical bonds are the covalent bonds and ionic bonds. Covalent bonds are bonds in which one or more pairs of electrons are shared by two atoms. Covalent bonds, in which the sharing of the electron pair is unequal, with the electrons spending more time around the more non-metallic atom, are called polar covalent bonds. In such a bond there is a charge separation with one atom being slightly more positive and the other more negative, i.e., the bond will produce a dipole moment. On the other hand, Ionic bonds are bonds in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other. In the extreme case where one or more atoms lose electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond. Covalent bonding is a form of chemical bonding between two non-metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds. Ionic bond, also known as electrovalent bond is a type of bond formed from the electrostatic attraction between oppositely charged...

...Polarity Management of Cost and Quality Dustin Klinger Kaplan University Polarity Management of Cost and Quality Polarities are interdependent pairs that support a common purpose yet tend to be contradictory of one other (Polarity Partnerships, para. 1). Some examples of polarities include: stability and change, individual and team, long and short term, autocratic and participatory and my topic, cost and quality. Any of these pairs are known to counter the other. In my case, it is important to note that when quality improves, cost generally increases and vice versa. Throughout this paper I will discuss managerial approaches to utilize these two concepts to your advantage without ever overlooking either of them. It is important to embrace the fact that there are polarities everywhere we turn and instead of trying to fight against them, we should develop their concepts to make us more complete. Larry Hirschhorn has argued that in order for managers to become proficient in managing polarities, they must develop a set of “rules of thumb” for when they encounter different circumstances. They establish these rules with the hopes of somewhat standardizing their way of thinking as well as how to allocate resources for each instance. The guidelines are generally developed to recognize patterns and opportunities. Hirschhorn recommends managers create a 2 x 2 table to help illustrate this concept and to categorize its different states. Each axis would include a “hi” and...

...About Syria attack, President Obama is attempting to employ U.S. military to act against Syria. And there is some of my point of view about this incident. * Three affective tactics to persuade people of the USA and other country about attacking Syria. 1. On the summit of the Group of 20 (G20), Obama tried to persuade the leader of those countries to interfere the Syria war by telling them the people of Syria is suffering from the Sarin ( the poison gas) if they don’t stop the government force there. Some of the country, like France, is showing their support toward U.S. intervention. There were ten countries signed up to the call for a strong international response with U.S. that they want the president of Syria to stop using chemical weapons. 2. Showing the video about how the people of Syria are suffering from the Sarin to the Congress. And some of the congressman took the advice and try to care about the human right in Syria. 3. He seeks the permission from the US Congress and attempts to show the respect to people. Consequently, he didn’t establish any military moves toward Syria now. "I was elected to end wars and not start them" he said. It seems persuasive to me. * One thing that he didn’t to but I think it’s affective Tell the American what is worthy this time when the United States interfere the war of Syria. Every time U.S. interferes some war that is not in the USA, people died because of “the world peace”? And it also cost a bunch of...

...IRAC Brief: JP Morgan Chase Settles the London Whale This is a case study analysis of a current legal case regarding the governance principles of regulatory compliance and the methods used to manage risk arising. The briefing of this case will utilize the IRAC method of case analysis to give a breakdown on the case of JP Morgan Chase on regulatory violations and risk management. The IRAC method will address I - Issue, R - Rule, A - Analysis, and C - Conclusion which will provide a researched assessment of the trading loss violations on this case. Please read and review this analysis of the case utilizing IRAC method of case analysis. Issue JP Morgan Chase permitted traders in its London office to allocate magnified values to transactions and cover up huge losses as they continued to explode. Two traders could face criminal charges for fabricating records to cover up losses. JP Morgan’s charge to the $6 billion oversight in trading loss is the first for a main company since the Securities and Exchange Commission revised its practice of letting firms pay fines without admitting fault. An admission by JPMorgan could provide a pattern for pursuing other admissions in Wall Street cases. The Justice Department is aggressive in getting JPMorgan to admit that from 2005 to 2007, it sold mortgage securities to investors without fully warning of the risks. By wanting the bank to admit some responsibility, officials hope it will caution other corporations to double check before taking...

...Neurotransmitters: Acetylcholinesterase Abstract: A series of three labs were combined to observe the effects of some common biological enzymes: Catalase, Tyrosinase, and Acetylcholinesterase (AChE). Enzymes are catalytic proteins, that when present in a chemical reaction, are able to lower the action potential needed to create the reaction without being destroyed or altered themselves in the process. In Part A, my hypothesis stated that when Catalase is combined with H2O2 the rate of conversion to water and oxygen gas should double when 5-10 drops of enzyme is added and quadruple when 10-20 drops are added. In Part B, my hypothesis stated that increases in enzyme concentration or buffer pH the substrate of the final product will yield increased substrate, also, if the substrate concentration is increased then the enzyme will be less diluted, the buffer pH will increase, or there will be a temperature increase. In Part C, my hypothesis stated that tacrine will have an inhibitory effect on AChE, and that those effects will increase as the level of concentration increases. In all three labs I postulated that increases in temperature and concentration levels and would increase the rates and decrease time to form chemical reactions. We setup each lab with a series of increased concentrations and a control trial using DiH2O. We observed the results using the following instruments: LabQuest and LabQuest App, a Spectrometer, an Oxygen Gas Sensor, LoggerPro software, and class...
