Homeland Security Risk Management Olgera Haywood American Military University Introduction Homeland security in United States comprises of complex and competing requirements, incentives, and interests that need to be managed and balanced effectively to achieve the desired national objectives. Security, resilience and safety of the country are endangered by different hazards such as cyberspace attacks, terrorism, manmade accidents, pandemics, natural disasters and transnational crimes which are part of external risks affecting homeland security. Internal risks such as projects costs, workforce management and acquisition operations also affect the security. Internal and external risks impact the country in diverse ways such as human death, environmental degradation, injuries, economic loss, among other negative impacts. Department of Homeland Security and other involved partners should be in a position to manage and understand the different risks to security. The security state current is dynamic and relying on past cannot completely inform decision making (CRS, 2007). Risk management therefore is a process of analyzing, communicating and identifying risk and avoiding, accepting, controlling or transferring the risk to acceptable limits considering benefits and costs of measures taken with the aim of ensuring improving security decisions.

Observations of Chemical Changes free essay sample

All substances (matter with a definite composition) have characteristics that be used to identify them. These characteristics are referred to as properties. The properties of substances can either chemical or physical. Physical properties are those that do not change the chemical nature of a substance. Dying an Easter egg blue will alter the appearance of the egg not it’s make up. If the nature of a substance were to be altered then the chemical properties have been affected. A good example of a chemical change can be seen repeatedly in our textbook each time a chemical is oxidized. For more examples of physical and chemical substance properties see the map in figure 1. 1. Physical properties are quiet simple to calculate. Determining the solubility or boiling point of a chemical for example is pretty cut and dry. I think this is most likely due to the fact that physical changes do not alter the identity of a substance. Chemical changes, in my opinion, are not as easy to recognize as physical changes. Chemical changes are determined by how a substance reacts with one or more substances when forming compounds. These reactions are known as chemical reactions. (Plaster, Soil Science pg. 13) Not all chemicals will react when mixed with another chemical; while some chemicals can be explosive or toxic when mixed with other chemicals. In previous science courses (soil science and chemistry), and in every day life, I have learned there are â€Å"observable clues† that can be used as indicators of a chemical change. When I drop an Emergent-C tab into a glass of water it reacts by fizzing or bubbling quickly until dissolved. The bubbles are created from gas production. It drives me nuts when a restaurant offers Splenda instead of Sweet-n-Low as a sugar substitute because Splenda doesn’t completely dissolve (insoluble) decaffeinated iced tea. Some Splenda will remain suspended in my glass while some settles in the bottom of my glass. The tea and Splenda formed a compound, but the insoluble Splenda is called a precipitate or a double replacement reaction. (Brown, pg. 47) Ever mixed two clear chemicals together and the compound magically turned a different color. I learned quickly, during a lab about reactions in aqueous solutions last semester that a color change can be a good indicator of a chemical reaction. Prior to beginning my chemistry labs this semester I watched a Lab Paq safety video. The Lab Paq host reminded me that chemicals can react to absorb or give off heat. Temperature changes are classified as exothermic, heat/energy releasing or endothermic, heat/energy absorbing and are both chemical reactions.

Calculations/Errors Before beginning my chemical changes exercise I tried to determine the chemical changes and reaction products.

I observed double replacement reaction, precipitation reaction, reactions between various chemicals with Bromothymol Blue and Phenolphthalein (acid/base indicators). In the e-text book, Chemistry: The Central Science (Twelfth Edition) , I learned about properties of acids and bases in chapter 4. I was able to use what I learned to aid in understanding what I observed chemically during this exercise. BTB or Bromothymol Blue (acid/base indicators – by color) Acids turned orange with a hint of yellow at the start of the reaction. Bases turned dark blue. Phenolphthalein (acid/base indicator – by color or lack of) Neutral and acidic solutions had no chemical reaction (color change) when combined with the phenolphthalein. Bases on the other hand turned as pink as a radish. Rate of Reaction I’m curious as to way some reactions take so much longer than others. I wonder if it has something to do with how strong of an acid or base it is, or something to do electromagnetic attraction of anions and cations, maybe solubility plays a big role. I’m uncertain what factor or factors determine the rate at which a reaction takes place, but I’d be an interesting topic to look into Knowing the rate of a reaction can aid in maintaining safety or enable one to speed up or slow down a desired reaction. I am now wondering all the possible benefits of knowing the rate of a reaction when it comes to soil and water remediation. Hmmmm†¦ Most importantly, I learned more about physical and chemical changes that could aid in the identification of unknown substances. I was able to practice the scientific method, write and predict chemical equations, get better acquainted with ionic charges (cations and anions), enforce what I learned in chapter 3 about replacement reactions, precipitates and more. I experienced first-hand the indicators that signal a chemical reaction is taking place (e. g. : gas evolution, heat/energy change, color change, and precipitate reaction). IX. Questions A. I could test for the presence of sodium hydrogen carbonate (sodium bicarbonate) in a household product by repeating one of test conducted early in the lab and comparing results. Test: 1. Place 2 pipet drops of the household cleaner into one well. 2. Add 2 drops of HCl (hydrochloric acid) into the same well. 3. Observe, waft smell, record 3. If bubbles are produced then CO2 gas was created and if a Clorox bleach smell is produced then I would assume sodium bicarbonate is present in the cleaner B. Phenolphthalein remains clear when testing an acid or a pH neutral substance and pinkish-red when testing a base. Bromothymol blue turns yellow when testing an acid, green when pH is neutral and blue when testing a base. I tested the household cleaning chemicals below, recorded my observations, and recorded my interpretation of the results. Data Table 2: Reactions Observed Well # Chemical Reaction Interpretation A 12 Windex BTB Dark blue in color, no precip. Windex is basic B 12 Dish Soap BTB Bright yellow color, Dish soap is surprisingly acidic C 12 Lysol Pheno. Light pink color, no precipitate Lysol is basic C. Suppose I found a sample of solution with a faint odor resembling vinegar. I then decided to verify the presence of vinegar by adding a few drops of phenolphthalein. The sample turned pink. I could assume the odor may resemble vinegar, but the sample does not contain vinegar. Vinegar is an acid. In earlier test, only bases turned pinkish-red when mixed with phenolphthalein. D. Using BTB (bromothymol blue), I selected five flavors of the new wave Vitamin Water to test their claimed pH neutrality. Three of the flavor-samples turn a murkey green when combined with BTB, indicating the likelyhood of acid/base (neutral) balance. Of the two remaining samples, one turns slightly yellow when combined with BTB, indicating the pH is most likely 6. 0 or slightly lower and more acidic then the first three samples. The fifth and final sample tested remained blue when combined with BTB, indicating the pH is 7. 6 or higher and is more basic then the first three samples. E. I devised the simple test below to confirm the presence of lead (Pb, an ingredient in Grecian Formula) in a new brand of hair tonic. Test To test the tonic for lead (Pb) I would combined a sample of Pb with potassium iodine (an acid). KI and Pb() react to form a precipitate when combined. If the hair tonic and potassium iodine react to form a bright yellow precipitate I could assume the tonic does indead contain lead. Background Knowledge (Includes: lead, aqueous reactions, precipitate, solubility, replacement reaction) Chemical Equation Pb(NO3)2(aq) + 2KI(aq) PbI2(s) + 2KNO3(aq) Double Replacement Reaction Pb2+(NO3-)2(aq) + 2K+I-(aq) Pb2+I-2(s) + 2K+NO3-(aq) Atoms like to have full valence (outer) electron shells with eight electrons. Depending on how full the valence shell of an element is determines its ability to attract another atom’s electrons. Ions are charged atoms which have lost or gained electrons. Cations are positive charged ions. While negative charged atoms are called anions. Ever heard the saying, â€Å"opposites attract†? Well, the saying is true in chemical reactions. The reaction between lead nitrate and potassium iodine is a double replacement reactions, Meaning the oppositely charged cations and anions â€Å"switch partners†. Net Ionic Equation Pb(NO3)2(aq) + 2KI(aq) PbI2(s) Group one potassium (K), iodine (I), and nitrates (NO3) are soluble in aqueous solutions. Lead (Pb) is soluble with Nitrates (NO3). However, Lead (Pb) is a not soluble with any group 17 elements (F-, Cl-, Br-, I-, and At-). Therefore, two soluble reactants combined to form one insoluble product: a solid bright yellow precipitate. G. During this lab exercise I allowed the chemicals NH3 and CuSO4 to react. The reaction produced a dark blue precipitate known as tetramminecopper(II) sulfate. The ammonia fumes have been known to waft from animal excrement and interact with nearby copper ammunition cartridges, damaginh the casing. Suppose a sample of this metal casing was collected from the site for analysis A researcher recorded the mass of a graduated cylinder filled with 10. 0 mL of water as 14. 1 g. (1mL = 1cm3 = 1g for pure H2O) Volume of H2O: 10. 0 mLMass of Graduated Cylinder: 4. 1 g She placed a chunk of the metal casing into the cylinder and recorded the volume as 11. 4 mL, its mass increased to 16. 6 g. Volume of metal chunk: 1. 4 mLMass of metal chunk: 2. 5 g Density = Mass/Volume or D= m/V in g/cm3 or g/mL D = 2. 5 g/1. 4 mL D = 1. 79 g/mL The density of the metal chunk is 1. 79 g/mL. H. Two pipette drops of each liquid in the table below were allowed to react for one minute. After reviewing the data recorded I can assume the unknown is NH3. I came to this conclusion because the unknown turned pale pink in phenolphthalein an indication it is a base with a pH above 7. 6. The unknown didn’t react with NaHCO3 indicating the substance must be soluble and relatively basic. The student could confirm their choice by testing the unknowns response to CuSO4. If the solution changes to baby blue and a cloudy precipitate forms then the student could assume the unknown is indeed CuSO4. Unknown Phenolphthalein The phenolphthalein turned the unknown pale pink. NaHCO3 No reaction seen Pb(NO3)2 White solid (precipitate formed) AgNO3 Nothing happened I. This lab exercise allowed me to observe several chemical and physical changes. It also improved my ability to recognize the difference between chemical and physical changes. Below I identified and explained some chemical and physical changes.

Night Time In Denver Essays - Carrie, English-language Films

Night Time In Denver One day Carrie and Jerry were walking home from school, and there was an ambulance at the next door neighbors house. They asked what was wrong and they found out that Mr. Zooman (that is what the kids call him) had a heart attack (that's what they thought). And what do Carrie and Jerry care about it? He was a weird person anyway. That night Carrie and Jerry decide to climb the big brick fence that surrounded the house. They just wanted to check out what was there. They got their flashlights and shovels and started walking toward the house. They climbed the fence and had a rough drop down the fence. They looked around and saw huge plans; they were shaped like animals. Jerry looked up and saw a lion with wings; it was so big that he could fit his head into its mouth...If he wanted to. Jerry and Carrie were both scared, but they did not admit it. Ten they herd a rustle, Jerry said "here kitty kitty." Just to try to convince him that it was only a cat. But Jerry and Carrie both knew it was the plants. They started to dig in the roots and chop them down, but one grabbed Jerry and smashed him to the ground. They ran away. This time when they climbed the fence to run away it was much harder, but the did. The next day in school they talked about what happened and what they could do about it. Jerry had an Idea. They were going to have to go to visit Zooman in the hospital, to find out how to get ride of them. They thought about this. Why didn't he get ride of them? They would soon find out.
