Developing a successful business model without strong control mechanisms will only generate temporary profits. The purpose of control mechanisms in business models is to protect the created values and profit streams from being reduced by competitors‚ partners or strong customers. The last decades have shown a rapid growth in customer power at the same time as new technology and services are being replaced faster. Even though control always has been an important part of the business model

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

proton with a functional group. The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products. The methyl benzoate reaction product‚ methyl nitrobenzoate‚ was determined to be meta-substituted and the acetanilide reaction product‚ nitroacetanilide‚ was determined to be para-substituted.

Nitration of Naphthalene Wed 2/25/2015 Lab report # 1 Abstract: The purpose of this experiment was to nitrate naphthalene with nitronium ion‚ which is formed at low concentration from a reaction of nitric acid and sulfuric acid. The percent yield from the experiment was 54.4% of the product‚ and the melting point of the possible results were 59 °C for 1-nitronaphthalene‚ and 78°C for 2-nitronaphthalene. Introduction: Polynuclear aromatic hydrocarbons such as naphthalene can be nitrated

Title: Nitration of Methyl Benzoate Objective: To prepare methyl-3-nitrobenzene from nitration of methyl benzoate. Results and calculations: Density = 1.094 g/ml = Mass of methyl benzoate = 1.094 g/ml x 2.8 ml = 3.0632 g no. of mol of methyl benzoate = = 0.022499 mol 1 mol of methyl benzoate produced 1 mol of methyl m-nitrobenzene. Therefore‚ 0.022499 mol of methyl benzoate produced 0.022499 mol of methl
