claim). -The Salicylic acid that I obtained had a melting point range around 157-158 degrees Celsius for Part A. For Part B the melting point range was 156-157.5 degree Celsius. Part B‚ I would say the sample is less pure because of the notion that impurities lower the melting point. Since part A ‘s melting point was higher and closer to the melting point of the pure sample‚ it was more pure. The pure Salicylic acid that I got the melting point for had a range from 158-159 degrees Celsius. The impure

experiments 3.2 and 3.4 was to determine whether the melting/freezing or boiling point is a characteristic of the property of the substance. A characteristic property is a certain property (physical or chemical) that can determine or identify the substance. For example‚ density and magnetism are two characteristic properties that can distinguish objects from one another. In this case‚ we are figuring out whether the melting/freezing or boiling point of a substance will help us find out what the substance

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Project SCIE206-1203A-32: Biology 07/05/2012 Abstract The effects of rock salt‚ which is used for melting snow in the winter time‚ works in a variety of ways. The main reason is to aid in melting of the snow making it easier for individuals to drive their vehicles and also the sidewalk for pedestrians. Overall‚ the rock salt used for melting snow‚ works but it have some pros and cons about it‚ but using it wisely should be the key to its success. Might grass growth

A turning point occurs when there is a decisive change ; all previous ideas are overturned and the results are especially beneficial for society. From the 1830s onwards there were many turning points. However‚ in order to be the turning point of the century the change in provision must have the greatest positive impact on the paupers’ lives and there be a shift in ideas of ‘deserving’ and ‘undeserving’ poor. One turning point in provision for the poor was the 1834 Poor Law Amendment Act which overthrew

Malcolm Gladwell presents his thesis of small tipping points to a bigger problem in the very title of the book. Within the first chapter‚ he introduces the simple idea that there are three simple “tipping points” that causes a large problem. From there‚ he elaborates on his different causes in a full chapter with other examples to help prove his point. Gladwell uses plenty of examples that the general population could pull from memory easily and then proceeds to use these examples to make more challenging

The Tipping Point: How Little Things Can Make a Big Difference Literature Review of the Tipping Point American culture changes dramatically over time. Malcolm Gladwell (2002)‚ author of The Tipping Point‚ presents a theory of social epidemics. Gladwell’s notion on epidemics and human behavior uses a combination of scientific fields such as psychology‚ epidemiology‚ sociology‚ intragroup and intergroup dynamics to explain the spread of social and cultural behaviors.

finding the melting point of the unknown compound. The theory is that if a substance is pure‚ it will have a very specific melting point‚ within one or two degrees Celsius. This is in opposition to a mixed‚ or contaminated substance‚ which will have a broad melting range. Therefore‚ when we mix our unknown with samples of phenacetin and acetanilide‚ whichever mixture has a more accurate melting point will tell us what our unknown is. It is also important to make sure that the resulting melting points
