“Back in my days” We are all well aware of the classic case of cultural difference. And who are the prime targets of this epidemic; it’s us and our parents. Let me start with a story. I was schedule to leave on the red eye at 11 45 pm‚ unfortunately a very close friend of mine 25th birthday bash coincided with the date of my departure. I had this entire strategy meticulously mapped out in my head‚ I was going to leave home around 8- 8:30pm‚ atend ari’s party‚ be there for an hour or so and still

1. (a) Explain how a firm operating in an oligopolistic market might attempt to increase its market share. Oligopoly: A market or an industry dominated by a few firms The key point in Oligopoly is that whether the number of the firms in the industry is big or small‚ a large proportion of the market/industry’s output is shared by just a small number of firms. The number of ‘a few’ firms that dominate the market varies depending on the sections of industry. For example 90% of petrol sold in a

Niharika Palakodety‚ Victoria Wang‚ and Grace Xiong Mrs. Rhonda Smith Honors Chemistry Period 4 13 May 2012 Redox Reactions Lab Report We wished to investigate the oxidation number of a metal that would form aqueous ions when reacted with an aqueous nitrate salt. For this purpose‚ we chose to investigate the reaction of solid copper metal‚ in the form of a wire‚ with aqueous silver nitrate. Before we began the lab‚ we hypothesized that when silver nitrate‚ AgNO3‚ reacts with copper‚ Cu‚ the

Purpose: The purpose of this experiment is to observe the colours produced when the solutions of metal ions are heated to high temperatures‚ then to explain the results in terms of the energy levels of the metal ions. Lastly‚ to use the flame colours to identify a series of unknowns. Hypothesis: Substance being tested Predicted flame colour NaCl(s) Yellow NaCl Red-Orange NaNO3 Dark Orange LiNO3 Red Sr(NO3)2 Dark Red KNO3 Blue-Indigo Ba(NO3)2 Yellow-Green Cu(NO3)2 Green Ca(NO3)2

Laboratory 3: Molarity Of Saline Solution Data: Please write your observations about the appearance of the solution. 1. Normal Saline- The solution appeared clear at the start with slight particles showing‚ once adding the salt it still appeared clear. 2. Nasal Irrigation Saline- Solution appeared cloudy once adding the salt and baking soda‚ then it turned semi-clear about 30 secs later; it was more concentrated than the normal saline. Results: 1. Determine the molar mass of NaCl. Show the workup
