of acetylsalicylic acid Results and Data treatment (A) Preparation of aspirin i) Details about the reactants Reaction of the acetylation of salicylic acid is following From the balanced reaction above‚ it can be seen that the stoichiometry between salicylic acid and acetic anhydride is 1: 1. In this experiment‚ 21.7mmol of salicylic acid was used to react 6.0mL of acetic anhydride and salicylic acid was limiting reagent. The expected amount of salicylic acid used: 21.7/1000*138

Separation or Assimilation? Our country‚ The United States of America‚ was essentially founded on the principles of life‚ liberty‚ and the pursuit of happiness through solidarity of human kind. In Bernard R. Boxill’s article‚ "Separation or Assimilation‚" he fundamentally poses the Hamletesque question: to assimilate or not to assimilate. Subsequent to the dilemma of some black cultural nationalists‚ whom not only argue for assimilation of the black American populace‚ but also believe that this

PURPOSE The purpose of this experiment is to become familiar with the separation of mixtures of solid and learn separation techniques based on the chemical properties of a substance. PROCEDURES 1. Separating out the Iron a. Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal

Experiment 2: Separation of a Mixture of Solids Purpose: This experiment allowed me to learn different separation techniques for various substances based on their specific chemical properties. Procedure: I began this experiment by using a magnet to pick up and collect the iron filings out of the mixture. Then the sand was separated by placing the mixture into a beaker and boiling it in distilled water in order to dissolve the salt and benzoic acid‚ once boiling the liquid was poured out leaving

Abstract In this experiment paper chromatography was used in order to identify two unknown amino acids using eight known amino ones. The two unknown ones were identified by comparing the distance they travelled up the chromatography paper and their Rf values to the corresponding values of the other eight known amino acids. The unknown amino acids identified were Glycine and Methionine. Introduction Proteins in cells are important in many ways. There are different types of proteins such as

Separation of Powers under the United States Constitution The term separation of powers originated with the Baron de Montesquieu‚ a French enlightenment writer and John Locke‚ an English Philosopher. However‚ the actual separation of powers amongst different branches of government can be traced to ancient Greece (Kelly‚ 2014). Separation of powers is a political doctrine of constitutional law which creates the division of governmental responsibilities into different branches in order to limit one

Separation of a Mixture of Solids My Flow Chart First remove iron filings with magnet since this is the only substance in the mixture that it is magnetic and will be attracted to a magnet. Second remove the sand by adding the mixture to hot water‚ which the other two substances are soluble. Third remove the benzoic acid since this is less soluble in cold than salt by cooling the mixture in the heated water. This will then leave the table salt behind in the water as the last substance.
