“All ethical statements are relative.” (By examining the justification for and implication of making this claim‚ decide whether or not you agree with it). The term ‘ethical’ can be defined as ‘morally correct’‚ however this leads to the question of what do we define as ‘morals’? A ‘moral’ can be simply defined as ‘concerned with the principles of right and wrong behaviour and the goodness or badness of human character’. The word ‘relative’ refers to something‚ which is ‘considered in relation

Laboratory RECRYSTALLIZATION OF ACETANILIDE USING WATER AS SOLVENT Lagarteja‚ M.C.B.; Lim‚ H.G.N.; Lizo‚ K.J.R.; *Macalino‚ M.D.L.; Macapala‚ C. 2D-Pharmacy‚ Faculty of Pharmacy‚ University of Santo Tomas Abstract Recrystallization is a technique used to purify organic solids. This method involves dissolving of a solute in a solvent and inciting the solute to produce a precipitate from a solution. In this experiment‚ acetic anhydride was added to the mixture of 2mL aniline and 20mL of distilled water

Synthesis of p-Nitroacetanilide (electrophilic aromatic substitution) In this experiment‚ we convert acetanilide to p-nitroacetanilide. [pic] The mechanism for the nitration is that of electrophilic aromatic substitution. The nitronium ion is directed to the positions ortho and para to the acetamido (-NHCOCH3) group. This occurs because the resonance electron-releasing effect of that group increases the electron density at those positions‚ helping to stabilize the intermediates that

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

For this lab‚ I decided to focus on relative dating in studying things of the past. I found this the most interesting form to examine. Relative dating doesn’t give one an exact date but can give a good time frame of an artifact. It is used by looking at sequences and layers with regards to the soil for excavating. This is known as stratigraphy (Bahn‚122). It was inspired by geology in looking at layers of soil (Dating Archeology‚ 2016). As an archeologist using this method‚ one would say‚ “the underlying

Relative Velocity and Riverboat Problems On occasion objects move within a medium that is moving with respect to an observer. For example‚ an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example‚ a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this‚ the magnitude of the velocity of the moving object (whether it be a plane or a motorboat)
