The Fear Of Having A Son Essay - 1665 Words

The Fear of Having a Son In the beginning of this article, Andrew Reiner described his experience with having a son. He stated, â€Å"I was faced with one of my biggest fears about parenthood: having a son† (Reiner, 2016, para. 6). Reiner elaborated on the growing trend of parents wanting female children instead of males. The article mentioned that adoptive parents are even willing to pay an average of $16,000 more in finalization cost for a girl instead of a boy (Reiner, 2016, para. 10). Reiner also noted that the boys-will-be-boys behavior does not originate with them (Reiner, 2016, para. 12). Instead, it is a product of their environment. He cited â€Å"... parents tend to touch infant boys less often and more roughly than infant daughters and that daughters are handled more gently and protectively†¦ (Reiner, 2016, para. 12)† This displayed how societal norms shape behavior attributes that can be seen as non advantageous. Towards the end of the article, Reiner emphasized that we should empower our daughters and empower our sons with the same emotional literacy skill set and expansive worldview we teach our daughter (Reiner, 2016, para. 18). He finished the article with a short anecdote about how his son only wanted his attention and that is why he was acting out.

Recalled to Life in A Tale of Two Cities by Charles...

How can someone be â€Å"recalled to life†? It is a blazing strange statement. In Charles Dickens’ novel, A Tale of Two Cities, there are many people who are or help someone else to be recalled to life. In particular, there are three main characters that experience this. Dr. Manette, Charles Darnay, and Sydney Carton are all resurrected, as implied by the statement â€Å"recalled to life†. Dr. Manette is resurrected, or recalled to life, multiple times in A Tale of Two Cities. Lucie Manette, Dr. Manette’s daughter, always helps in saving him. Dr. Manette’s story begins with him being imprisoned in the Bastille. He gets out after eighteen years and stays at Monsieur Defarge, an old servant’s house. This is where Lucie meets him for the first time.†¦show more content†¦After marrying Lucie, Charles gets a letter from an old servant, saying he needs to go to Paris to help the servant out of prison. When Charles goes back he is arrested for being an aristocrat and for being an emigrant. His trial is one year and three months after he is imprisoned. Dr. Manette saves Charles Darnay during his first trial because he related to the crowd with his story of his imprisonment in the Bastille. The people took pity on Darnay and were inspired by Manette’s story and allow Charles to go free. This was the second time Charles is recalled. Charles is condemned again by three people who are later revealed as Monsieur and Madame Defarge, and Dr. Manette. He then goes back to prison to await his second trial. At this point, Sydney Carton is also in France. He knows of Charles’s danger and is planning a way to save him. Charles is waiting in his cell for his trial when Sydney comes in to talk with him. Sydney gets Charles to switch clothes with him and gives him something to sedate him. Once he is asleep and they have swapped clothes, John Barsad takes Charles out to an awaiting carriage. The next day Sydney goes to t he guillotine in Charles’s place.

The current situation in Asia is marked by wars and conflicts in the Middle East, terrorism in some parts of same location, increased and perpetual religious autocracy. In the same place, countries like Japan and China are improving the technological facilities while the Koreans are busy maintaining ‘peace’. In all the circumstances that surround the state of Asia, one realizes that culture has a major part; indeed it forms the only fulcrum upon which all acts are carried. The culture in China supports communism and individual multinational companies are only allowed to work or operate in this nation if they are ready to abide by existing rules and regulations of the country. The religious affiliation of people of this country also allows them to work effectively in the team, and even cater for the elderly.

Experimental Research Elements free essay sample

In the United States the development of a new drug, for human consumption is a long and difficult process requiring many levels of testing. Mandated by the food and drug administration (FDA) the rigorous process of new drug development can consists of at least four phases. If the FDA approves the new drug to be safe and effective for humans, generally, from start to finish the entire process of new drug development, take an average of 12 years of experimental research costing the pharmaceutical company millions of dollars. Recently a pharmaceutical company wants to test a new sleep aid for humans, using a scenario like this can provide more specificity on exactly how the potentially new sleep aid goes from the laboratory to a consumer. In new drug development, researchers systematically use the experimental research placing emphasis on key elementshypothesis, randomization, treatment group, control group, and measurement (University of Phoenix, Week Three Supplement, 2012). We will write a custom essay sample on Experimental Research Elements or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Each key element of experimental research corresponds to a specific phase in new drug development. Possibly the most important element is hypothesis testing that occurs in the pre-clinical research phases of new drug development. Hypothesis testing in the pre-clinical phase is necessary to support the claim made by the pharmaceutical to convince the FDA that the new sleep aid shows is effective and safe to test on humans (Simonoff, 2010). In this case, the hypothesis is that the new sleep aid is more effective in reducing the symptoms of insomnia. Using evidentiary support in pre-clinical trials of the new sleep aid did prove the claim of efficacy and that it is safe to test on humans in clinical trials. The next step in new drug development occur in three phases of clinical trials in which researcher’s further use experimentation to test the hypothesis of the sleep aide on human subjects. Critical to clinical researchers/scientists is to reduce confounding factors (health, age, culture, gender, and race) as this can affect the results of the experiment (Myers, 2012). Therefore, clinical scientist or researchers randomly assign the human subjects to a treatment group, or control group. The treatment group exposes the independent variable to the subjects whereas the subjects in the control group do not have exposure to the independent variable (Comer, 2012). By comparing the treatment and control groups, the experimenter can better determine the effect of the independent variable— or measure the variable that indicates if the hypothesis is true or not (Comer, 2012). Therefore, in terms of measurement the independent variable to measure is the new sleep aid in which experimenters did expose to participants in the treatment group with symptoms of insomnia. Proving effective, in terms of the time it takes for one to fall and stay asleep the experimenters might consider the new sleep aid or independent variable as therapy, or a way of treatment for participants with symptoms of insomnia. Furthermore, the clinical scientists, researchers, and or experimenters consider the dependent variable the medical or psychological improvement caused by the independent variable. Clinical trial phases in new drug testing lasts up to three years in which the new sleep aid continues further testing on thousands of existing patients (who volunteer) in clinics and or hospitals (Today’s Science, 1995). If perhaps, the new sleep aid meets FDA approval, this may occur at least ten to twelve years later after which experiments will continue to determine if there are long-term side effects of the new aid. It is evident that in the United States, new drug development is a long, costly process including but not limited to hypothesis testing, pre-clinical, clinical trials, thousands of brave subjects in treatment and control groups (and more). In the hope to provide safe, effecting drug treatment to help in the treatment of illness and disease in human and animals dedicated scientists, various specialists, and researchers press on using the key elements of experimental research to do so.

Analysis of Silver in an Alloy Essay Example

Analysis of Silver in an Alloy Essay Example Analysis of Silver in an Alloy Paper Analysis of Silver in an Alloy Paper Analysis of Silver in an Alloy Introduction In this experiment an alloy of silver will be analyzed to determine its silver content. The silver-copper alloy will be dissolved in nitric acid, the silver will be precipitated as silver chloride, and the silver chloride will be filtered, washed, dried and its mass determined. From the mass of the silver chloride formed and the mass of the original sample, you will be able to calculate the percent of silver in the alloy. Because the results are based on the mass of a product, this procedure is classified as a gravimetric analysis. Silver and copper are very nonreactive metals. Neither will dissolve in hydrochloric acid or sulfuric acid. The oxidizing acid nitric acid, HN03, is required. In acidic solutions the nitrate ion is an excellent oxidizer, and it will oxidize Ag(s) to Ag+(aq) and Cu(s) to Cu2+(aq). The reduction product is the gas NO. As the colorless nitrogen monoxide gas forms, it immediately reacts with the oxygen in the air to produce the orange-brown gas N02. The half-reactions for the oxidation of silver and copper by nitric acid are as follows: Ag(s) > Ag+(aq) + e- Cu(s) > Cu2+(aq) + 2e- 4H+(aq) + NO3- (aq) + 3e- > NO(g) + 2H2O(l) Once the silver and copper ions are in solution, they can be separated from each other by precipitating the silver ions as silver chloride. Silver chloride (AgCl) is very insoluble in water, while copper(II) chloride (CuCl2) is soluble. The addition of chloride ions to the solution will precipitate essentially all of the silver and none of the copper. The silver chloride precipitate is then filtered from the solution. Experimental Methods Follow protocol as listed for Laboratory Experiment #1 in â€Å"Experiments for Advanced Placement Chemistry† by Sally Ann Vonderbrink, Ph. D. With these modifications: instead of using a Gooch Crucible and fiber glass pad, we used a Buchner Funnel and filter paper. Theoretical Methods Balance out the half reactions of Ag and NO3- 3( Ag(s) > Ag+(aq) + e- ) 4H+(aq) + NO3- (aq) + 3e- > NO(g) + 2H2O(l) 3Ag(s) + 4H+(aq) + NO3- (aq) > 3Ag+(aq) + NO(g) + 2H2O(l) Calculate amount of NaCl needed to precipitate NaCl > Na+ + Cl- Ag + Cl > AgCl(s) .3015 g Ag 1 mol Ag 1 mol Cl 1 mol NaCl 58. 44 g NaCl 107. 7g Ag 1 mol Ag 1 mol Cl 1 mol NaCl = . 1635g NaCl multiply needed NaCl x 2 .1635 x 2 = . 3269 g NaCl Calculate the percent of Ag in the Alloy .3555 g AgCl 1 mol AgCl 1 mol Ag 107. 87 g Ag = . 2675 g Ag 143. 23 g AgCl 1 mol AgCl 1 mol Ag % Ag = . 2675 g Ag x 100 = 75. 25% .3555 g AgCl Calculate the percent error between percents of Ag in an Alloy % error = actual – experimental x 100 = actual = 90. 08 – 75. 25 x 100 = 16. 46 % 90. 8 Results Experimental Results: We first weighed our original sample of silver alloy, as shown in table 1. Then added 10 ml of nitric acid to the silver alloy which dissolved, by heating, the alloy into silver and copper ions as nitrite gas escaped in an orange cloud. After the alloy was completely dissolved we added a solution of sodium chloride dissolved in distilled water. When calculating out sodium chloride we doubled the necessary amount to make sure that a full and complete reaction occurred when once again heating. After letting that sit over night covered in para-film to form large precipitate particles of silver chloride we filtered the particles from the solution with the buchner funnel. We used a diluted nitric acid as our wash because it helped to keep the precipitate from forming to small particles. We then heated the sample so we could weigh out the final product as shown in table 1, and then calculated the percent of silver as shown in table 3. Theoretical Results: In table 2 it shows the necessary amount of sodium chloride that was needed for this reaction to four decimal places. While in table 1 it is shown that we had to round to two decimal places lacing a small error. And not only that but also the fact that as table 2 shows that the final amount needed was . 0131 g less to the actual mount that we added from table 1. During the procedure our percent error must of have come from loosing the silver ions. After heating we had to wash the moisture of the watch glass back into the beaker and there could have been a possibility that we didn’t wash of all of the silver back into the beaker. When it precipitated, some of the particles may have peptized causing us to filter out some of the silver chloride precipitate. Also when removing the filter paper from the buchner funnel some of the precipitate may have been lost, which is just due to human error. Which all experiments have. Discussion In the lab you must first dissolve the alloy in nitric acid; if the allot doesnt completely dissolve it may cause some error in your final result because not all of your silver ions were dissolved. You then must make a solution of distilled water added with sodium chloride. Once you calculate the amount of sodium chloride needed you must double the amount for the experiment to push the reaction to a full completion. This essentially should precipitate all of silver and none of the copper. No accurate balance is needed to measure out the sodium chloride because as long as you have an excess of sodium chloride to provide enough chloride ions to precipitate all of the silver ions its is safer than having a need of more chloride ions.. Before adding the sodium chloride solution to the dissolved silver you must rinse any moisture on the bottom of your watch glass back into the beaker of dissolved silver so that way not silver is lost. Thus causing a source of error if not all of the silver ions were still in the beaker upon adding the sodium chloride solution to precipitate the silver as silver chloride. You wash to remove all of the other chemicals from the silver chloride precipitate. There will be copper(II) nitrate, nitric acid and excess sodium chloride. These have to be washed through to make sure only (wet) sodium chloride is left in the filter. The nitric acid in the wash water will not interfere with the weight of the silver chloride because it will be washed through with the filtrate leaving the solid sodium chloride in the filter paper. If the silver chloride is not cool when its mass is determined the calculated percent would be too high, because if we do not dry the precipitate in the oven then the water in the filter paper and solid will affect the weight making it higher. We need for that excess water to be dried out to have a good calculation. We dont use hydrochloric acid to both dissolve and precipitate the silver because the acid cannot dissolve either silver or copper because they are insoluble when mixed. It could work to make a precipitate but not to dissolve the alloy. A special filter crucible rather than plain filter paper is used because it gives rapid filtering and helps pull the soluble material and water through. Also you have to wash several times so this speeds up the process. Observations made throughout the experiment is that when the solution of the alloy when dissolved with the nitric acid, were being heated a yellow orange gas of nitric escaped which smelled like rusted metal. The liquid that was left behind had an aqua color to it. But once the sodium chloride was added it turned into a cloudy blue. When this new solution is heated for 15 minutes the sodium chloride begins to precipitate into white clumps of the bottom of the beaker. When precipitate is filtered and dried in oven it then looks like white dust particles. Conclusion In this lab, the percent of silver in the alloy was calculated by dissolving the alloy in nitric acid to precipitate the silver as silver chloride. By weighing the mass of the precipitate you are able to calculate the percent of silver in the original sample. Anytime you are wanting a quantitative percent of an element in an alloy dissolving it in a solution then precipitating the solution should give you the result s you want as long as it is insoluble in the reaction. Improvements that we could o made during the experiment are that my partner and I should have divided the lab in a better way in which we both could have the job done faster and with more patience. Because one of the sources of error that could be possible is that when we are washing the solution back into the beaker we could have not washed it properly and some silver could have been left behind.

However, the teaching staff is mainly made up of a white population.
