I have several oxidation states and I also have a very high melting point which is around 1337.33 Kelvin. That is very high‚ in Fahrenheit it is 1947.92 degrees and in Celsius it is 1064.18 degrees. I am also paramagnetic‚ which means that I have very weak attractions to magnetic forces and can only be attracted when

Cambodians Under Pol Pot Cambodia‚ a small country just west of Vietnam‚ gained independence after nearly 100 years of French rule. They first faced the problem of Communism during the Vietnamese Civil War. They remained neutral by contributing equally to North and South Vietnam. North Vietnam was a Communist country while South Vietnam was advised by the U.S. The Khmer Rouge‚ a group of Communist rebels‚ was led by Pol Pot. They soon took over Cambodia‚ killing hundreds of thousands of people

Over the centuries‚ immigration has benefited the United States for the use of slavery‚ but what about for the economy or just the country itself? The US has been given the name‚ “The Boiling Pot‚” because we have a lot of different races combined into one country. Have you ever wondered how the boiling pot could’ve just been some scrap metal if immigrants hadn’t come into the United States and built it a little? Some people think that immigrants just want to steal our jobs‚ but do they really? Maybe

I think a great way to describe Diversity would be the “melting pot theory” (Richard T. Schaefer‚ 2012‚ p. 24) America being the pot and the people who live here being the indredients within the pot. We are a huge group of indviduals who all add a little something to the country. Diversity is valuable for the mere fact that it allows everyone to learn something new‚ try something

#1: THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the

Pol Pot was Dictator of Cambodia and head of the Khmer Rogue from 1975-1979. The Khmer Rogue was a communist party within Cambodia. The Rogue first initiated a coup d’ētat in 1970‚ which sparked a civil war which lasted 5 years

PREPARATION OF ASPIRIN AND DETERMINATION OF THE MELTING POINT Ferrer‚ Lara Melissa V. Faculty of Engineering University of Santo Tomas Manila‚ Philippines ABSTRACT This experiment involved three steps: synthesis of aspirin‚ isolation and purification‚ and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst‚ phosphoric acid‚ H3PO4. When the aspirin was prepared‚ it was isolated and filtered. The percentage

ABSTRACT Determining the melting point of a solid organic compound is the easiest way to identify the compound and determine its purity at the same time. For actual samples of compounds‚ the melting will occur over a range of temperatures making the melting points into a melting “range”. The difference between the temperature at which the sample begins to melt and the temperature at which it finishes melting‚ or the magnitude of the melting range‚ is a very important criteria of determining the
