...I Intro In this lab we are going to observe chemical reactions. A chemical reaction is the rearrangement of stuff into new stuff. When a chemical reaction occurs there is color change, temperature change, energy change, gas release, odor, and precipitation. There are 5 different types of chemical reactions: synthesis, decomposition, single displacement, double displacement, and combustion. A chemical reaction has to be balanced because of the law of conservation of mass. Conservation of mass is mass neither created nor destroyed. The product has to be the same amount of substances as the reactants. II Purpose The purpose of this lab is to observe different typed of chemical reactions. III Data / Observations Reaction #1: 2Mg + O2 2MgO Synthesis * Burning magnesium metal turns it into an ultraviolet light while on fire. Product is a white powder. Reaction #2: Mg + HCl MgCl2 + H2 Single displacement * When magnesium was added to HCl, it started to bubble and the test tube became hot. When a flame lit on a wooden splint was added it made a loud pop sound. Reaction #3: (NH4)2 + CO3 (NH4)2 + CO3 Decomposition * Ammonium carbonate was added into a test tube and heated up it up with fire. After adding a piece of litmus paper a strong odor was released. The litmus paper turned from a color pink to a color of blue. Reaction #4: CaCo3 + 2HCl CaCl2 + H2CO3 Double displacement * When HCl was added to calcium carbonate it began...

...copper (II) nitrate (Cu(NO3)2∙3H2O) A complex ion has a metal ion at its center with a number of other molecules or ions surrounding it. These can be considered to be attached to the central ion by co-ordinate (dative covalent) bonds. The molecules or ions surrounding the central metal ion are called ligands. Simple ligands include water, ammonia and chloride ions. All ligands are lone pair donors. In other words, all ligands function as Lewis Bases. A base is an electron pair donor and an acid is an electron pair acceptor. Ligands like water, can donate a pair of non-bonding electrons(lone pair) intro a vacant orbital of a central metal ion and so dative covalent(co-ordinate) bonds hold a complex together. The central metal ion with vacant bonding orbitals can act as a Lewis acid. Ligands act as Lewis bases by electron pair donation to form the metal-ligand bond. Apparatus : filter paper , Buchner funnel, adapter, suction filtration flask, spatula, graduated cylinder, watch glass, glass rod, pipette Chemicals : water, copper (II) nitrate (Cu(NO3)2∙3H2O), 1:1ammonia solution, acetyl acetone Procedure : 1. 6g of copper(II) nitrate...

...COMM/225 06-13-2013 Palmer Pellham Intro Since the early 1900’s, media has played a vital role in our society. Media has influenced generations of Americans from the record player, Morse code, and radio. Our society has experienced a phenomenal rise of mass media since the beginning stages of the television in the 1940’s. Since then, media has been responsible to bringing live reports on national emergencies, increased the number of voters, and even helped assist in the resignation of a President (Richard Nixon). Digital technology has literally changed the way media is distributed, produced (special effects), and delivered. The Print Press About mid1440, a tinkerer by the name of Johannes Gutenberg thought of a concept of creating letters out of metal while melting alloys. According to Vivian, J. (2011), “The growing quantity of printed materials fueled literacy and, slowly, a standardization in written languages. What Gutenberg begat can be called the Age of Mass Communication, but his innovation also spurred Western civilization into the ongoing Age of Science and Age of Reason. Civilization hasn’t been the same since.” Since the 1800’s, the print press has helped us deliver messages of importance like pamphlets of anti-slavery propaganda to help deter slavery in the Deep Old South, help religion by producing mass scripts (like the Bible) for circulation, and even has helped the casual citizen stay informed...

...Re-Organization and Layoff: Decision Making SAMANTHA STINSON PHL/320 March 14, 2016 Jason Miller Re-Organization and Layoff: Decision Making Introduction When a company chooses to conduct a mass layoff, the employees are not the only ones affected, the ethical business environment and economy are also at threat. Handling a company’s finances can be very puzzling and companies that find it difficult to overcome this task, experience a downturn, weakening business, and when this occurs, the need to find solutions to relieve their financial issues become critical. The purpose of this paper is to provide a recommendation from the two solutions provided in Week 4, how this solution benefits the middle-income customer, business decisions involved in the process, and what resources a company would need to implement that decision. Employee Buyout When a company is enduring extreme financial hardships, they may be able to encourage their workers to resign or retire voluntarily. “A buyout typically includes an offer of severance pay for a particular length of time and the continuance of other fringe benefits.” (D. Sullivan, 2016). The employer is entitled to negotiate the terms so they are not only favorable to the company but the employee too. A positive side effect the company gains from offering buyouts instead of laying off or firing employees can minimize possible lawsuits and bad press. There are several laws and regulations that must be followed when pursuing the employee...

...Organization of a book fair I have chosen to do my research paper on the organization of the book fair for a non-profit company in a major United States city. This book fair will take place in San Francisco, California. There are many non-profit organizations here in San Francisco that could use the help of a fundraiser. There are schools, health organizations, medical clinics, homeless shelters, and food banks to name a few. Successful planning and organizing a fundraiser will make this project successful. To begin the planning stage of this fundraiser, I will need to do much research. This is going to be a book fundraiser. Looking at cost effective ways to hold this fundraiser is crucial since the outcome is to raise money for a particular organization. I will first look at a venue. Is it less expensive to hold a fundraiser on the Internet or is it more cost efficient to hold it a location. Having a fundraiser on the Internet does not seem a personable to me. However, it might be more cost efficient. Holding a fundraiser at a physical location seems that it would be more successful. The advertising and promotion of a fundraiser are just as important. Getting the most exposure to the public will help with the success of my fundraiser. I will need to research to find out if advertising and promoting this book fundraiser is more or less expensive than with actual physical advertising. I am leaning more to the physical...

...Psychology is defined as the scientific study of the behavior of individuals and their mental processes (Gerrig & Zimbardo, 2010). When you take psychology in college, it is to teach you how to understand how people are different and allow you to be non-judgmental. Being in the Navy, I feel that I developed the ability to be open-minded very early on in my career. This is because the military recruits people from all over the country, from the ghetto to the country club. I deal with all walks of life (race, religion, gender) on a daily basis. What I do not get to see in the Navy is people with mental disabilities and disorders. This course has taught me that approximately half of the populations of the United States have experienced or are experiencing some type of psychiatric disorder (Gerrig & Zimbardo, 2010). The average person looks down on someone with any type of disability. They usually label them as deviant when their disorder allows them to commit a crime. What people don’t understand is that some of these people cannot control what they are doing. The only way for them to satisfy an urge is to do what they are thinking about. An example of this would be a serial killer. Serial killers usually have an internal motive for killing repeatedly, whereas a murderer usually commits one crime for a very specific reason. Serial killers need to satisfy some urge, and they do that through killing. However, not all people that have unquenchable urges resort...

...Nutrition and Fitness Paper To remain healthy it is imperative that I consume a well balanced diet, and incorporate physical activity into my current lifestyle. Through assessing my current level of fitness and nutritional status, I identified new habits that could assist me in becoming healthier. By integrating these new habits into my current lifestyle, I will be able to maintain a healthy body weight, and furthermore improve my general health. Obesity is a leading health concern in the United States, placing individuals at risk to other serious diseases. Discussing some of these associated risks emphasizes the importance of personal nutrition and fitness. Personal Fitness and Nutritional Habits I believe I am an active individual and eat healthy most of the time but recognize that there is always room for improvement. My lifestyle both personal and professional is hectic not leaving me much free personal time. Therefore, it is imperative that I develop new habits to improve my current fitness level and nutritional status. I try to work out a couple of times a week at a local gym but find that I often skip scheduled sessions because of other commitments. Concerning nutritional habits, I am guilty of missing breakfast and lunch resulting in me consuming junk foods until dinner in the evening. My diet at this time is lacking the recommended amounts of dietary fiber, and I need to modify my intake of dietary fat. Health Risks Associated with Obesity According to Lazarou...

...SC155 - INTRO TO CHEMISTRY: MATTER AND EQUILIBRIUM Indigestion and Titration: An Acid-Base Titration Imagine yourself as the Lead Analytical Chemist at Kaplan Industries. Your first big assignment is to investigate the strength of several commercial antacids for the Food and Drug Administration (FDA). They have sent five antacids to be tested with a back-titration that works as follows: • • • First, each antacid tablet is mixed with 40 mL of 0.1 M HCl—this acidic solution is the same stuff that is in stomach acid, and one antacid pill is nowhere near enough to neutralize all 40 mL of the acid. So, to see how much extra help each antacid pill needs to neutralize 40 mL of 0.1 M HCL, you add 0.05 M NaOH drop-by-drop to back-titrate the solution until the pH is neutral. What this means is that, the stronger the antacid tablet, the less NaOH it will take to help bring the acid to neutral. (In other words, the stronger antacid tablets counteract more of the original HCl, leaving the solution closer to neutral before the NaOH is added.) Here are your results: Maalox Mass of one dose antacid mL NaOH used in backtitration 20.0 g Tums 21.0 g Mylanta 18.0 g CVS brand 18.3 g Rennies 17.5 g 24.1 mL 22.4 mL 20.0 mL 19.9 mL 24.4 mL 1. Which is the strongest antacid, on a single-dose basis? Which is the weakest? Explain and show your calculations. 2. Which are the strongest and weakest, on a by-weight (mass) basis? 3. When people do back titrations, they usually watch...

...Hacktivism, Freedom of Speech or Cyber Terrorism? Josh T. Diehl ITT-Tech Institute Abstract I will be doing my research paper on Hacktivism and looking into the subsector that is known as “Anonymous”. Hacktivism in itself is the use of computers and computer networks to promote political ends. To see this for what it truly can be, you must look at it with the understanding that it can be carried out under the same premise that proper (and skillful) use of technology can produce results similar to these of conventional acts of protest, activism, and civil disobedience. I plan on exploring whether it is freedom of speech or cyber terrorism, keeping an open mind when conducting my research will be the key to the integrity of this paper. I plan on researching online articles and post from credible sources. I will make set times while I am not at work to research and write this. Body First we need to look at what exactly is hacktivism and who practices it. Hacktivism in itself is defined as “The use of computers and computer networks to promote political ends, chiefly free speech, human rights, and information ethics. It is carried out under the premise that proper use of technology can produce results similar to those of conventional acts of protest, activism, and civil disobedience.” Certain groups such as Anonymous use this form (among others) as their way to speak out against what they see as injustice. We need to look closely, past the top layer of information, to...

...How does the concept of complexity assist you in evaluating issues for sustainability? 2nd- I'll identify the three systems I outlined in the intro (economic, political, social), the ones that impact on the transport system 3rd- I'll identify the relationships between the scale, systems and complexity 4th- Discuss how this impacts the decision making for sustainability. Given its land constraints, Singapore’s overall transportation strategy cannot rely on building roads and more roads to serve its populace’s travel needs. It needs a comprehensive and affordable public transport system and sustainable demand management tools. Hence, its recently launched Land Transport MasterPlan is based on making public transport a choice mode, while continuing to manage road usage and to meet the diverse needs of its travelers. A key element to meet these objectives is the continued use of road pricing. Road pricing has long been associated with Singapore, starting way back in June 1975. Many changes have been made to the road-pricing scheme since that time. Started as a manual scheme based on paper permits and hence, using little technology, it has evolved to become a sophisticated system today, involving various technologies. The economic principles for road pricing however, continues to be valid but the charging structure had been evolving to keep the scheme effective, and deriving benefits to the community as a whole.

...when it is consumed. One of the biggest and most common effect is the how bad it is able to control your brain. Whether it is from, blurring your vision to even impairing your judgment on a certain subjects that you may have to face in your life. That is the biggest reason why marijuana is considered to be illegal. Another reason is because for the longest time the government could not find a way to properly tax the selling and growing of marijuana. In the 1930s was the time when marijuana was considered to be a controlled substance because of a man named Harry J. Anslinger who brought before Congress the proposal of banning marijuana. Because of the mass effects that it has on the human body and the people that it affects around them. When WW2 was started the American people were asked to grow hemp or marijuana again because of the mass amount of material that can be harvested from it. Then in 1973 the Bureau of Narcotics was born and placed marijuana and hemp under the Controlled Substance Act, which was created in 1970, to make sure that it was fully illegal in the United States. Because marijuana was...

...In this era of the new and social media, does it really matter who owns the `mainstream’ media? “It is by the goodness of God that in our country we have those three unspeakably precious things: freedom of speech, freedom of conscience, and the prudence never to practice either of them.” (Clemens, 1897) Foreword According to the Universal Declaration of Human Rights written up by the United Nations, its states that, “Whereas disregard and contempt for human rights have resulted in barbarous acts which have outraged the conscience of mankind, and the advent of a world in which human beings shall enjoy freedom of speech and belief and freedom from fear and want has been proclaimed as the highest aspiration of the common people” (UN, 1948). Articles 19 to 21 specifically target the freedom of thought, conscience and belief of human rights that a Democratic government must abide by and Egypt is no exception. Arab Spring Turmoil has been brewing in Egypt, causing great pain to its inhabitants, destroying homes and families and creating complete mayhem in the process. The first marked incident according to The Guardian is on the 1st of January 2011; a suicide bombing attempt took place outside a Coptic Church in Alexandria. By the 25th of January Egypt finally joined the Arab Spring alongside Tunisia, Yemen and Algeria. The ‘Arab Spring’ was an activist movement by several Middle-Eastern countries in an attempt at freedom from political and religious oppression and authoritarian...
