Three Races to Immigrate to the United States In Search for the Promised Land

Three Races to Immigrate to the United States In Search for the Promised Land Introduction: The Mystery of the United States It seems that the USA has become the Promised Land for the people dissatisfied with the quality of living standards in their own country; therefore, these people head to their Mecca, the country where every cloud has a silver lining. In the light of the fact that at present, a number of the USA cities are overpopulated, the issue concerning immigration remains unresolved.Advertising We will write a custom essay sample on Three Races to Immigrate to the United States: In Search for the Promised Land specifically for you for only $16.05 $11/page Learn More Unless the given issue is tackled, immigration into the USA might soon become impossible. Therefore, it is necessary to consider what races are most likely to immigrate to the USA in the nearest future, as well as which of these races have the most legitimate reasons to be accepted into the realm of the USA democracy. When the Oriental Culture Merges with the We stern One: The Chinese The first candidates to migrate to the United States, the Chinese, nevertheless, are bound to face a number of difficulties when acculturating to the American lifestyle and trying to build their own mini-society within the realm of the American culture. However, it seems that the Chinese actually integrated into the American society quite a while ago. According to the existing evidence, the concept of an American–Chinese culture emerged in the distant 1850, when the first immigration wave swept New York and other major cities (Liu). In addition, it is noteworthy that the Americans have been maintaining business relationships with the Chinese for quite long. That being said, it would be reasonable to suggest that the Chinese migrant population is bound to find a common language with the Americans at least in the business field. In Search for Better Working Options: The Mexicans There is no point in denying that the economical and financial state of Mexic o is more than deplorable. The state remains on the list of the so-called third world countries, and with the budget that the government has at the disposal, as well as the policy of the state, there seems to be no way out at present. According to the existing evidence, most of the Mexican population lives beyond the poverty threshold (Ceballos and Palloni). Therefore, it seems rather fair that the Mexican people should search for the place where their professional assets and efforts are going to be evaluated fairly and paid accordingly. However, when considering the migration of the Mexicans into the United States, one rarely takes the possible results into account. To start with, the process of acculturation is bound to take a considerable amount of time. In addition, it is highly recommended that immigrants into the United States, as well as any other state of the world, should perfect their professional skills in order to remain well paid and become successful.Advertising Looking for essay on rhetoric?

Pushing the Science to Its Limits: The Russians and the Brain Drain Naturally, when analyzing the reasons that make people from other countries move to the United States, people rarely consider the possible contributions of the immigrants into the American culture, science and society. When thinking of the opportunities that the so-called â€Å"brain drain† from other states to the USA offers to the latter, it is also necessary to evaluate the quality of education in the state, which the i mmigrants come from. According to the latest research, compared to the USA standards, the greatest quality of education can be observed in such countries as New Zealand and South Korea (Miller, Laugesen, Lee and Mick). In the light of the fact that over the past few years, the standards of living in the new Zealand have dropped and a number of people have been considering the option of moving to the United States, it will be reasonable to allow the New Zealanders become the residents of the United States of America. The given situation will be a graphic example of a reciprocal process that has to take place between the receiving country and the immigrating nation. The same can be said about the residents of South Korea; according to the existing researches, they have very high educational standards. However, when choosing between the two nations, one must mention that the South Korean living standards are much higher than the ones of New Zealand at present, which means that the New Zealanders need the USA assistance more. That being said, the immigration of the New Zealanders into the USA should be considered. Conclusion: Acculturation, Togetherness and Other Related Issues There is no doubt that the USA offers a plethora of opportunities for people to develop professionally, contributing to the state and being able to run their own business, at the same time maintaining their national and cultural identity. However, the problems of acculturation and the loss of identity are still worth bringing up. No matter how well developed the structure of a diaspora is, its members will still be isolated from their culture, which will inevitably lead to the loss of cultural roots. Therefore, immigration will always presuppose a dilemma between economical independence and national identity.Advertising We will write a custom essay sample on Three Races to Immigrate to the United States: In Search for the Promised Land specifically for you for only $16.05 $11/page Learn More Ceballos, Miguel and Alberto Palloni. â€Å"Maternal and Infant Health of Mexican Immigrants in the USA: The Effects of Acculturation, Duration, and Selective Return Migration.† Ethnicity and Health 15.4 (2010): 377–396.

Calculating Concentrations with Units and Dilutions

Calculating Concentrations with Units and Dilutions Calculating the concentration of a chemical  solution  is a basic skill all students of chemistry must develop early in their studies. What is concentration? Concentration refers to the amount of solute that is dissolved in a solvent. We normally think of a solute as a solid that is added to a solvent (e.g., adding table salt to water), but the solute could easily exist in another phase. For example, if we add a small amount of ethanol to water, then the ethanol is the solute, and the water is the solvent. If we add a smaller amount of water to a larger amount of ethanol, then the water could be the solute! How To Calculate Units of Concentration Once you have identified the solute and solvent in a solution, you are ready to determine its concentration. Concentration may be expressed several different ways, using percent composition by mass, volume percent, mole fraction, molarity, molality, or normality. Percent Composition by Mass (%)This is the mass of the solute divided by the mass of the solution (mass of solute plus mass of solvent), multiplied by 100.Example:Determine the percent composition by mass of a 100 g salt solution which contains 20 g salt.Solution:20 g NaCl / 100 g solution x 100 20% NaCl solutionVolume Percent (% v/v) Volume percent or volume/volume percent most often is used when preparing solutions of liquids. Volume percent is defined as:v/v % [(volume of solute)/(volume of solution)] x 100%Note that volume percent is relative to the volume of the solution, not the volume of solvent. For example, wine is about 12% v/v ethanol. This means there is 12 ml ethanol for every 100 ml of wine. It is important to realize liquid and gas volumes are not necessarily additive. If you mix 12 ml of ethanol and 100 ml of wine, you will get less than 112 ml of solution.As another example, 70% v/v rubbing alcohol may be prepared by taking 700 ml of isopropyl alcohol and adding su fficient water to obtain 1000 ml of solution (which will not be 300 ml). Mole Fraction (X) This is the number of moles of a compound divided by the total number of moles of all chemical species in the solution. Keep in mind, the sum of all mole fractions in a solution always equals 1.Example:What are the mole fractions of the components of the solution formed when 92 g glycerol is mixed with 90 g water? (molecular weight water 18; molecular weight of glycerol 92)Solution:90 g water 90 g x 1 mol / 18 g 5 mol water92 g glycerol 92 g x 1 mol / 92 g 1 mol glyceroltotal mol 5 1 6 molxwater 5 mol / 6 mol 0.833x glycerol 1 mol / 6 mol 0.167Its a good idea to check your math by making sure the mole fractions add up to 1:xwater xglycerol .833 0.167 1.000Molarity (M) Molarity is probably the most commonly used unit of concentration. It is the number of moles of solute per liter of solution (not necessarily the same as the volume of solvent!).Example:What is the molarity of a solution made when water is added to 11 g CaCl2 to make 100 mL of solution ? (The molecular weight of CaCl2 110)Solution:11 g CaCl2 / (110 g CaCl2 / mol CaCl2) 0.10 mol CaCl2100 mL x 1 L / 1000 mL 0.10 Lmolarity 0.10 mol / 0.10 Lmolarity 1.0 M Molality (m) Molality is the number of moles of solute per kilogram of solvent. Because the density of water at 25 °C is about 1 kilogram per liter, molality is approximately equal to molarity for dilute aqueous solutions at this temperature. This is a useful approximation, but remember that it is only an approximation and doesnt apply when the solution is at a different temperature, isnt dilute, or uses a solvent other than water.Example:What is the molality of a solution of 10 g NaOH in 500 g water? (Molecular weight of NaOH is 40)Solution:10 g NaOH / (40 g NaOH / 1 mol NaOH) 0.25 mol NaOH500 g water x 1 kg / 1000 g 0.50 kg watermolality 0.25 mol / 0.50 kgmolality 0.05 M / kgmolality 0.50 mNormality (N) Normality is equal to the gram equivalent weight of a solute per liter of solution. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given molecule. Normality is the only concentration unit that is reaction dependent.Example:1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles of H ions. On the other hand, 1 M sulfuric acid is 1 N for sulfate precipitation, since 1 mole of sulfuric acid provides 1 mole of sulfate ions. Grams per Liter (g/L)This is a simple method of preparing a solution based on grams of solute per liter of solution.Formality (F)A formal solution is expressed regarding formula weight units per liter of solution.Parts per Million (ppm) and Parts per Billion (ppb)Used for extremely dilute solutions, these units express the ratio of parts of solute per either 1 million parts of the solution or 1 billion parts of a solution.Example:A sample of water is found to contain 2 ppm lead. This means that for every million parts, two of them are lead. So, in a one gram sample of water, two-millionths of a gram would be lead. For aqueous solutions, the density of water is assumed to be 1.00 g/ml for these units of concentration. How To Calculate Dilutions You dilute a solution whenever you add solvent to a solution. Adding solvent results in a solution of lower concentration. You can calculate the concentration of a solution following a dilution by applying this equation: MiVi MfVf where M is molarity, V is volume, and the subscripts i and f refer to the initial and final values. Example:How many milliliters of 5.5 M NaOH are needed to prepare 300 mL of 1.2 M NaOH? Solution:5.5 M x V1 1.2 M x 0.3 LV1 1.2 M x 0.3 L / 5.5 MV1 0.065 LV1 65 mL So, to prepare the 1.2 M NaOH solution, you pour 65 mL of 5.5 M NaOH into your container and add water to get 300 mL final volume
