In "Spanglish" author Janice Castro defines Spanglish as "a common linguistic currency wherever concentrations of Hispanic Americans are found" but unlike other "broken English efforts" Spanglish has been widely embraced by "Spanish speaking immigrants and native born Americans alike" (76-7). Janice Castro in "Spanglish" describes the many forms Spanglish exemplifies. Rather than declare "go to the supermarket" one would say "ir al supermarket" (77). Yet the phenomenon‚ Castro explains‚ is not limited

Synopsis The purpose of this experiment was for students to prepare some simple organic compound and to purify the compound by recrystallisation. This experiment allowed the students to conduct the synthesis of aspirin‚ acquire the skills of recrystallisation using normal filtration and reinforce the technique of the melting point determination. The method used to synthesize aspirin was esterification by reacting salicylic acid with acetic anhydride with the presence of dehydrating agent‚ conc

Colton Kuhlers Chemistry Paper Organic vs. Non-Organic What should I eat‚ organic or non-organic? This has been is hot topic a lot now that the United States is trying to go healthy. For years people have been researching which is healthier‚ more economical‚ and the most available than the other. It is hard to know what to buy when one researcher says organics better and another researcher says non-organics better. Let me take this topic into more depth to explain myself. First‚ let’s me describe

Title: to get organic food Specific purpose: Organic food advocates claim that organically grown foods are safer and more nutritious than foods raised with non-organic methods such as pesticide and non-organic fertilizer use‚ or antibiotic and hormone use. Thesis statement: Many people just don’t trust these chemicals and don’t want to put them into their bodies. Since virtually all non-organically produced foods contain residues of pesticides‚ fertilizers and other chemicals‚ the only way to

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

Test Bank for Chapter 4 Problem 4-1: Work through the simplex method (in algebraic form) step by step to solve the following problem. Maximize Z = x1 + 2x2 + 2x3‚ subject to 5x1 + 2x2 + 3x3 ≤ 15 x1 + 4x2 + 2x3 ≤ 12 2x1 + x3 ≤ 8 and x1 ≥ 0‚ x2 ≥ 0‚ x3 ≥ 0. Solution for Problem 4-1: We introduce x4‚ x5‚ and x6 as slack variables for the respective functional constraints. The augmented form of the problem then is Maximize Z = x1 + 2 x2 + 2 x3‚ subject to
