Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

The Post Modernism period just came after the Modern period but it is not clear or impossible to be said when it came. In other words the modern Period was the time when the world was recovered from World War 2‚ which started globalization. The Post Modernism is a concept that arrived an era of academic study about in the mid-1980s. There is a variety of concepts‚ architecture‚ music‚ literature‚ fashion‚ art‚ film etc. In the 1980’s the political climate changed. During that time Post Modernism

Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction

EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural

Kristen Coleman What is Post- Polio Syndrome? Post-polio syndrome (PPS) is an illness that causes symptoms to reappear in individuals who had recovered from polio decades earlier. After recovering from polio‚ some survivors find themselves afflicted again‚ facing a serious condition called post-polio syndrome. PPS is a condition in the nervous system that affects muscles and nerves. What are the symptoms of Post-Polio Syndrome? Symptoms of post-polio tend to show up in a patient gradually

BEHAVIOUR OF AMINO ACIDS IN SOLUTION Abstract In this practical the acid-base behaviour of amino acids was assessed. Amino acids are amphoteric. They have the basic (amine) and the acidic (carboxylic) functional groups. These show the same type of equilibrium reactions that all weak acids and bases undergo‚ and the relative amount of each can be altered by adjusting the pH of the solution. For this practical glycine was used as a model to show this unique nature of amino acids. A series of

Pierson v. Post Deciding Court: Supreme Court of New York Parties: Pierson v. Post Procedural History: Appellate Court ruled in favor of Post Facts: Post was in pursuit of a fox on a beach with his dogs and hound.

The Post-Ottoman Syndrome: A Never-Ending Problem In the novel War and Peace In the Middle East‚ author Avi Shlaim argues that Arab nations have been unable to escape the post-Ottoman syndrome. In particular he describes how the various powers inside and outside the region have failed to produce peace. While some of Shlaim’s arguments hinder the message‚ I agree with his overall thesis that the Middle East problems were caused and prolonged by the failure of both powers and superpowers to

The causes of acid rain are because of the emissions of sulphur dioxide and nitrogen oxides in the atmosphere. This is a result of pollution; sulphur dioxide primarily the result of industrialisation and coal fired power stations‚ and nitrogen oxides produced mainly due to car exhaust fumes. These either form wet or dry deposition‚ and the effects we can see today. It could be argued that once that the human race has used up all of the planets coal reserves‚ the problem of acid rain would disappear
