Experiment 2 Title: preparation of a halogenoalkane Objective: To synthesis 2-cholo-2-methylpropane by using corresponding alcohol and HCl(aq). The reaction is via SN1 of tertiary alcohol. Techniques: i) Distillation of the reactant and the product ii) Purification by separating funnel Theory: In the experiment‚ SN1 reaction take place‚ HCl is added to initiate the reaction. The R-OH attack the H+ with the lone pair on O. Then the R-O+H2 bond breaks the release a water molecule and

MAT 300 M&Ms® Project Part 5 (3 pts) Using the methods in Section 8.4‚ test the hypothesis (α = 0.05) that the population proportions of red and brown are equal (pred = pbrown). You are testing if their proportions are equal to one another‚ NOT if they are equal to one another AND equal to 13%. NOTE: These are NOT independent samples‚ but we will use this approach anyway to practice the method. This also means that n1 and n2 will both be the total number of candies in all the bags. The

Reasons for product standardization or adaptationThere are countless reasons for which firms standardize or adapt their product‚ but the bottom line is that‚ there is no firm that is at the extreme end of thespectrum of standardization and adaptation. This assertion is supported andevaluated by Gabrielsson (2004:41): “The standardization alternatives are aspectrum ranging from full standardization to an adaptive approach at differentlevels of marketing mix elements.

Standardization of the English Language There are several important events before 1500 that when listed together show a series of steps in the struggle for English language supremacy. These steps are mainly governmental‚ legal and official events that pushed English usage. In 1356 The Sheriff’s Court in London and Middlesex were conducted in English for the first time. When Parliament opened in 1362 the Statute of Pleading was issued declaring English as a language of the courts as well as of Parliament
