The objective of this lab was to identify an unknown compound by determining the melting point range using fast and slow ramps. Also‚ to determine the eutectic point of Urea and Cinnamic Acid. An unknown compound that was numbered 8 was chosen. A small amount of the unknown compound was placed in a weighing paper using a spatula. The weighing paper was folded in half twice and then was grinded using a spatula. After the unknown compound was grinded about 1-2mm was added into a capillary tube. A

person until you consider things from his point of view- until you climb into his skin and walk around in it” (Lee 33). That simple quotation has been echoed in many forms before‚ but always meant the same thing; think about things from the other person’s perspective before you start throwing stones. This is a good rule to help people discern whether someone did something and why a person acts the way they do. Nonetheless‚ there was once a time when a point of view was irrelevant. Once‚ people used

turning point in the Revolutionary War because it gave the army a backbone‚ made the soldiers stronger for upcoming battles‚ and helped them win alliance with the French.

#2: How does point of view in “Cathedral” determine the plot? What it means to “see” another frequently depends on the maturity level of the viewer. This point is powerfully made by Raymond Carver in his short story “Cathedral” about a man who is navigating life “blind”‚ despite having normal vision. Carver tells his story using the husband’s point of view as the husband meets his wife’s long time friend‚ Robert‚ a man who ‚ despite being physically blind‚ sees life clearly. The point of view in

“Point-of-Care Testing (POCT) is defined as tests designed to be used at or near the site where the patient is located‚ that do not require permanent dedicated space‚ and that are performed outside the physical facilities of the clinical laboratories” (Woodworth‚ Kirsch‚ & Sayers-Rana‚ 2012‚ p. 363). The results of the test are much faster than standard laboratory testing and treatment can be delivered in a timely manor. In addition‚ the results of the testing are immediately connected with the

We were tasked with finding the molar mass of an unknown compound using the colligative property of Freezing Point Depression. The way we did this was first finding the temperature at which ice crystals form for just regular BHT. Luckily thanks to our TA we were given temperature probes so we could pinpoint exact

To what extent was 1949 a turning point? The years between 1945- 1949 could definitely be seen as a turning point as there were increasing divisions in Germany as it was divided between the Allies without the Germans having any say in the matter. 1949 can be argued to be a huge turning point in German history as Germany was literally split down the middle. Change is most well seen in the German democratic Republic as the changes introduced by the Communists were most apparent in ending capitalism
