Data analysis will involve determination of copper’s concentration using Beer-Lambert law. During the analysis, relevant graphs and calibration curves will feature in establishing the relationship between experimental variables. In addition, relevant statistical tests, especially the t-test well are used in detecting significant differences between absorbance by reference and sample solutions. Discussion of results will lead to eventual conclusion regarding the amount of copper metal in a penny.

Technically, penny coins comprise of copper, zinc and metals in different proportions. In the past, copper metal was cheap. hence was used primarily in manufacture of coins. After 1980, copper metal became valuable and rare. Therefore, coin manufacturers used only copper coating in pennies and used primarily zinc in making the bulk part of the coins. With increasing value of copper, the metal’s composition in a coin keeps changing. The only way to determine the metal’s proportion today is to carry out quantitative analysis using reliable analysis methods like molecular spectroscopy.

Concentration and hence the quantity of a metal species within a mixture is determined through molecular spectroscopy. This means that metals contained by a penny must be converted into molecular species in order to employ spectroscopic analysis. Fortunately, copper and zinc form molecular species with different colors. Copper form deep-blue ions while zinc form colorless species (Smith 45). The variation in ionic colors for the two penny components forms the basis of spectroscopic differentiation between copper and zinc. In this context, both copper and zinc must be converted into their ionic species with distinct colors before proceeding with subsequent steps of the experiment. This explains why the experiment’s procedure involved dissolution of a penny in nitric acid.

Chemically, zinc is more reactive than copper.

Hi, I need help with essay on Expatriate Salespeople. Paper must be at least 250 words. Please, no plagiarized work!

es, there may be legal challenges that determine whether or not expatriate salespeople can be used or if the market is unable to support a full-time salesperson.

The times that there might be situations in which expatriate sales managers are supervisors of the foreign salespeople. However, there are some issues that should be addressed. Some of these include the inability to be able to communicate between the foreign sales team and the expatriate sales manager. Another issue that is often faced is when the expatriate is unable to adapt to the foreign environment in which they are required to work. Many times there may also be legal barriers that can be significant problems.

Many of the skills that an expatriate salesperson is required to do is to be nonjudgmental, be able to react professionally if there is frustration in a situation, and must be empathetic of other people’s needs based on their own standpoint rather than the salesperson’s own standpoint. A person must also have an interest in the culture and the people and be respectful. The family may include an interview with the candidate’s family to ensure that the person is right for the job because the family is typically the people who know the person the best and their ability to adapt and work in new areas. The candidate’s family is critiqued to see if there is a problem if the expatriate salesperson will be gone to a foreign country for a significant amount of time.

Expatriates returning to the United States are often dissatisfied because of a growing number of attrition of those who return. There is a much lower morale. Many times those coming from the U.S. find that there are several family related problems that have strained their ability to work things out by being away for so long. They are often dissatisfied because of the compensation levels and

Hi, I need help with essay on Exercises. Paper must be at least 500 words. Please, no plagiarized work!

This gives the appearance that I am not in my room. I love my colleagues, but they often distract me with gossip and stories about their personal lives. I do not want to visit during my planning period. Each day I try to make concrete lesson plans for the next several days. I then review these plans and make adjustments at the end of each day.

I never take lesson planning home with me. There is something about being in my classroom that actually helps me to visualize what will happen (or what is supposed to happen) with each lesson. Conversely, I never grade at school. Grading is kept for the end of the day. I actually find it relaxing in some ways. I will often put on soft background music and pour myself something refreshing to drink. Scoring writing does take more of my concentration. I usually will sit in my kitchen in silence to do this sort of grading. Everything else is done at a lap desk curled-up on the couch. Grading is usually the last chore I do before going to bed.

I same all of my documents directly to the hard drive of my computer. I rarely back them up because my computer is synchronized with the servers at school each day. I probably should have my own personal back up on a thumb drive of some sort. This would be a good practice because the tech personnel at my school are not really all that good a retrieving lost information. I know some teachers that have lost hundreds of documents and have never gotten them back because a server malfunctioned. I think I’ll start using a thumb drive tomorrow.

After viewing the video and reading the documents, I can see that I have good time management skills but there is room for improvement. I have a very good schedule for accomplishing all of the tasks required of a teacher, but I sometimes lack focus on those tasks. I do not group like tasks together very well. For example, I answer e-mails as they arrive in my mailbox all day long. This is not a good

nal integration with highly qualified management, external technical assistance, and good project communication (Applegate, Austin & Soule, 2009:317).

Low structured-high technology projects: These refer to projects that are even more complex, considering that such projects entail the combination of low technology and unknown outcomes (Applegate, Austin & Soule, 2009:351). Thus the level of uncertainty is very high, since the expectations are uncertain, while the technology being used is novel and experimental, putting such projects at a great risk of project failure. To avert the chances of such projects failing, the tools that are necessary are the internal integration and the external integration tools, comprising of teams of highly qualified developers, and the excellent application f communication skills (Applegate, Austin & Soule, 2009:317).

High structure-low technology projects: These are projects that have the lowest level of risk involved, since they comprise of well understood technology and well-defined outputs and user-requirements (Applegate, Austin & Soule, 2009:316). The essential tools for such type of projects include formal control of results and formal project planning.

Low structure low technology projects: This are projects with low levels of risk, because the technology applicable is well known, so the only difficulty is the high rate of volatility of user requirements (Applegate, Austin & Soule, 2009:313). Such projects require the application of good project communication and excellent external integration as the tools to assist in the ever-changing user requirement.

Before the incident: At this stage, the issues that need to be considered are the sound design of the project. Further, there also needs to be the consideration of the level of execution, where a high level of disciplined execution is required (Applegate, Austin & Soule, 2009:281). Further, it is important to have detailed documentation of all process and procedures, as

Hi, I need help with essay on Evidence For Hominid Evolution. Paper must be at least 500 words. Please, no plagiarized work!

This was the probable lifestyle of early man. Scientifically, nearly 98% of human genes and chimpanzees are identical showing the biological closeness to humans. The cardinal difference between the two is the human brain size that is larger and complex. This makes man to communicate through speech, walk upright among others (Ruse, p.23).

About five million years ago, australopithecines evolved from the apes. It had small canine and was bipedal. This was the earliest human species. There were two major australopithecine groups. robust and gracile. The main difference was the jaw and teeth size. From australopithecine, the next probable evolution was the Homo habilis. This represented the modern man and Louis and Mary Leaky in Tanzania found the evidence. The primate was bipedal, upright and would use forearm to handle tools and weapons. It had increased brain size than the former and climbed ability suppressed. They had opposable thumbs (Ruse, p.43).

From the Homo habilis, there came the Homo ergaster that led to Homo erectus. This then led to Homo sapiens. The changes in the humans also showed changes in other primates such as the Chimpanzee. However the primary characters of the family bond, use of hand remained. The Chimpanzees just like humans are in the ape family. The differences in brain size, fur and eyes demonstrate the evolution that has occurred. Many similarities point to a similar origin. The similarities include the family bonding, the use of facial gestures such as surprise and comfort, omnivorous in nature, bipedal (Ruse, p.69).

Neolithic revolution lead to a widespread change in human lifestyle from the era of hunting and gathering to agriculture and settlement era. This enabled the humans support the fast growing population. This Neolithic revolution has led to improved health and longevity as well as morbidity. With Neolithic
