Scarlet Letter Essays -- essays research papers fc
Similarities in the works of Nathaniel Hawthorne The Ambitious Guest is a short story bye Nathaniel Hawthorne that presents deadly irony. Residing in a notch in the mountains of New Hampshire, a cottage sits on the side of a steep mountain. In the house lives a family whose contacts with the rest of the world are from the travelers that pass by. One night when the family was huddled by the fire, a traveler stopped by. The family was happy to have a guest and the guest was happy to have people to talk to. The stranger, normally a quiet person, revealed his desires about life and death. The stranger wanted to be known and to have someone to love him and grieve of his death. The family agreed with him and they all talked about how nice it would be to live in a small town and get to know all the people living in the town. They then started talking about death and how they want to die with people remembering them when suddenly there is an avalanche. They all run out of the house and get killed by the falling rocks. The rocks completely missed the house but the people were never found in the rubble around the house. Most writers have a style in which they write and they follow this style through all their works. Nathaniel Hawthorne is no exception to this. In the Scarlet Letter and in The Ambitious Guest Hawthorne uses the same writing style for both so they have many similarities. Some of these similarities include references to symbols such as the forest, death, solitude and li...

Magnesium: Chlorine and Hydrogen Moles
ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The main purpose for this experimental lab is to determine the atomic weight of magnesium, as well as an underlying purpose in determining the relationship between moles evolved and consumed. This can be demonstrated by measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl > H2 + Mg2+(aq) + 2Cl- (aq)The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction. Procedure Step 1: Obtain a 600 mL beaker, and add 300 mL of water. Step 2: Add 30 mL of HCl (2M) to the beaker, and stir. Step 3. Add 10 mg of magnesium metal to the beaker. Step 4. Allow the hydrogen gas to evolve. All of the magnesium should be consumed. Step 5. Record the amount of hydrogen gas that has evolved using the ch emical property dialog.Observations and Results Moles of hydrogen evolved: 0. 000411 (4. 11 x 10-4th) moles of H2 evolved Calculated atomic weight of magnesium: Weight of Mg /moles of H2 evolved [24. 305g/mol / 0. 000411 = 59,136. 25 g/mol of Mg] As I continued with my experiment I came across a few observations that are important to bring to attention. As I added 10 mg of magnesium to the beaker of HCl, a shaded area appeared at the bottom of the beaker. Directly after, bubbles formed in the same beaker thus indicating the Mg was being consumed. DiscussionThe moles of hydrogen gas that have evolved during the experiment resulted in 0. 000411. The calculated atomic weight of magnesium is determined by the formula of; atomic weight of Mg (in grams)=weight of Mg consumed (in grams) / moles of H2 evolved, therefore the equation should be similar to this; [24. 305g/mol / 0. 000411 = 59,136. 25 g/mol of Mg]. This experiment is clearly a branch of stoichiometry because a reaction takes pl ace and it is the duty of the student to calculate or determine the relative atomic mass of Magnesium.

What Do Grad Schools Look for in Students
What do graduate admissions committees look for in potential grad students? Understanding what graduate schools look for in applicants is the first step to tailoring your experiences and application to make yourself irresistible to the graduate programs of your dreams.à An admissions committees goal is to identify applicants who will become good researchers and leaders in their field and on campus. In other words, admissions committees try to select the most promising students. They want students who have the ability to become an excellent graduate student and professional. The Ideal Grad Student The ideal graduate student is gifted, eager to learn, and highly motivated. He or she can work independently and take direction and constructive criticism without becoming upset or overly sensitive. Faculty look for students who are hard workers, want to collaborate with faculty, are responsible and easy to work with, and who are a good fit with the program. The best graduate students complete the program on time, with distinctionââ¬âand excel in the professional world. Some return to become professors at their alma mater. Of course, these are ideals. Most graduate students have some of these characteristics, but few will have all. Criteria Weighed by Admissions Committeesà Now that you know the standard that graduate faculty are looking for in selecting new graduate students, lets look at how faculty weigh the various criteria for admission. Unfortunately, there is no simple answer; each graduate admissions committee is a bit different. Generally speaking, the following criteria are important to most admissions committees: Undergraduate GPA (especially the last two years of college)Graduate Record Exam (GRE) scoresRecommendation lettersPersonal statement/essay Sure, you knew these things were important, but lets talk more about why and the part they play in admissions decisions. Grade Point Average (GPA) Grades are important not as a sign of intelligence, but instead, grades are a long-term indicator of how well you perform your job as student. They reflect your motivation and your ability to do consistently good or bad work. Not all grades are the same, though. Admissions committees understand that applicants grade point averages often cannot be compared meaningfully. Grades can differ among universitiesââ¬âan A at one university may be a B at another. Also, grades differ among professors in the same university. Admissions committees try to take these things into account when examining applicants GPAs. They also look at the courses taken: a B in Advanced Statistics may be worth more than an A in Introduction to Social Problems. In other words, they consider the context of the GPA ... where was it obtained and of what courses is it comprised? In many cases, its better to have a lower GPA composed of solid challenging courses than a high GPA based on easy courses like Basket Weavi ng for Beginners and the like. GRE Scores Clearly, applicants grade point averages are difficult to compare. This is where Graduate Record Exam (GRE) scores come in. Whereas grade point averages are not standardized (there are enormous differences in how professors within a department, university, or country grade student work), the GRE is. Your GRE scores provide information about how you rank among your peers (thats why its important to do your best!). Although GRE scores are standardized, departments dont weigh them in a standardized way. How a department or admissions committee evaluates GRE scores varies;à some use them as cutoffs to eliminate applicants, some use them as criteria for research assistantships and other forms of funding, some look to GRE scores to offset weak GPAs, and some admissions committees will overlook poor GRE scores if applicants demonstrate significant strengths in other areas. Letters of Recommendation Usually, admissions committees begin the evaluation process by considering GPA and GRE scores (or those of other standardized tests). These quantitative measures only tell a small part of an applicants story. Letters of recommendation provide a context within which to consider an applicants numerical scores. Therefore its important that the faculty who write your letters of recommendation know you well so that they can discuss the person behind the GPA and GRE scores. Generally speaking, letters written by professors known to committee members tend to carry more weight than those written by unknowns. Letters written by well-known people in the field, if they signify that they know you well and think highly of you, can be very helpful in moving your application towards the top of the list. Personal Statement The personal statement, also known as the admissions essay,à is your chance to introduce yourself, speak directly to the admissions committee, and provide information that doesnt appear elsewhere in your application. Faculty read personal statements very closely because they reveal lots of information about applicants. Your essay is an indicator of your writing ability, motivation, ability to express yourself, maturity, passion for the field, and judgment. Admissions committees read essays with the intent to learn more about applicants, to determine if they have the qualities and attitudes needed for success, and to weed out applicants who dont fit the program.
