Melting

I propose a film on the melting ice caps, using the character Reina as the reason that they are melting. She will be the reason for melting the ice caps due to humans came to her home and drill for oil where she lives. I chose to have both Greek and Japanese mythology because I thought it would be a great idea to see how the two cultures will come together. Since both countries are known by many people all around the world and because they are surrounded by the sea these two countries would be the

identified by specific physical properties such as its melting point. A compounds melting point varies depending on how pure the compound is, a higher melting point indicates a more pure compound. The purpose of this experiment is to determine the melting point of given crystalline substances as well as the identity of an unknown substance based on its melting point. The DigiMelt melting point apparatus is used in this experiment to determine melting points of different crystalline substances by allowing

Lab 1: Melting Points March 15, 2018 Tina He Lab Partner: Gian Izquierdo SCC 251.275B Instructor Professor Olga Lavinda Abstract This experiment was performed to determine the melting point ranges of standard substances, urea-cinnamic acid mixtures, and unknown substances. The melting point ranges were measured by observing the temperatures in which the substances began

display the melting point range of each of the chemicals tested. Table 1 represents the results found in part 1 of the lab. It was found that the 50-50 mix has the lowest melting point. This is likely because the less pure a compound is, the lower its melting point will be. The 50-50 mix is the least pure of the 3 compounds so therefore the melting point was lower. In Part two of the lab it was found that the melting point range of the unknown compound (shown in table 2) is closest to the melting point

The metaphor that I grew up with saying that we are all the big melting pot in the United States, however, with the implication listed beside that term I would honestly have to say I disagree with that statement or reference. The United States is more like a kaleidoscope, since I believe that many cultures are brought within the society, and the society as well as the groups adapt to fit the needs of those individuals cultures as well the society as a whole. Instead of treating people differently

solids is done by observing the melting point. This is important because if there is an impure substance the melting point would be depression and the melting range would be broader. By finding the melting point of a known substance one can then observe an unknown substance’s melting point to see if the points are the same and try to figure out the unknown. Experimental Section: The first known substance we used was Biphenyl. 68 degrees Celsius is the known melting point. We used the capillary

Introduction: Melting point and Boling point are two fundamental physical properties that are commonly used to identify unknown compounds, to verify already known compounds, and to determine the purity of compounds.2 If the compound is a solid, the procedure for melting point determination is followed. However, if it is a liquid a boiling point technique must be performed, such as distillation or refluxing.2 The melting point determination consists of five major steps: obtain the sample and make

Abstract: The melting point and mixed melting point methods were used to determine identity and purity of samples. The melting points were obtained from phenacetin, acetaminophen, tartaric acid, and 9:1 mixture of phenacetin and acetaminophen by using an apparatus. The melting point range of phecacetin, acetaminophen, tartaric acid, and 9:1 mixture of phenacetin and acetaminophen were 123.4-124.8oC, 154.4-155.1oC, 154.3-157.5oC, and 104.3-114.9oC respectively. With a melting range of 121.8-123

TECH0701: Measuring the Melting Points of Compounds and Mixtures Introduction This exercise dealt with the melting points of pure mandelic acid and benzoic acid. The eutectic temperature and composition of mandelic and benzoic acid mixtures were determined. And finally, an unknown was identified by its mixtures and melting point. The melting point of a compound is used by organic chemists not only to identify the compound, but also to establish its purity. To determine the melting point two temperatures
