“The USA was not a ‘melting pot’ but a ‘mosaic’ of different cultures in the period 1890-1910’ Do you agree? According to some historians‚ the USA in 1890 had become a ‘melting pot’ of different cultures‚ meaning that the people who had immigrated to America had left their old traditions behind to start a new country free from outdated laws; this idea was also linked to American Exceptionalism as America was ‘Exceptional’ for these reasons. Many historians argue against this idea as there is plenty

Have you ever heard that America is a melting pot or a salad bowl? The metaphor for the melting pot is unfortunate and misleading for America. A more accurate metaphor would be a salad bowl‚ for the salad bowl can be very different from the melting pot because of all its ingredients can make it distinguished from the melting pot. Even today Americans are calling America a salad bowl instead of a melting pot. Whereas it once was a melting pot but soon changed. There have been many questions

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

student from Singapore‚ I am alarmed about the catastrophic consequences of climate change. It is already happening in our lives. Rising sea levels caused by the melting glaciers poses a direct threat to my home. Island nations and coastal cities will suffer the inevitable if we do not act now. In six degrees‚ Mark Lynas warned the impending arctic tipping point‚ once passed‚ the melting of the glaciers cannot be reversed‚ leading to a loss of habitable environment. However‚ I believe that the situation

is one of the many ideas that are illustrated throughout Gloria Anzaldua’s “How to Tame a Wild Tongue”. The language you speak is a part of your culture‚ and your culture is what defines a person the most. Living in a country that is seen to be melting pot of many cultures and heritages‚ you are bound to encounter someone of another culture but that doesn’t mean we suppress their ability to represent who they are because of their lack of knowledge pertaining to the primary language used in this

#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

VI: Conclusion: The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compound changes to a liquid when the molecules acquire enough energy to overcome intermolecular forces holding them together in an crystalline lattice structure. The melting point range is defined as the span of temperature from the point at which the crystals first begin to liquefy to the point at which the entire sample is liquid. This data can be tabulated experimentally

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest

America: The Melting Pot The term the melting pot was coined in 1782 by J. Hector St. John de Crevecoeur. It was a term used to describe the new country and all of its new inhabitants. Where people from different countries and different races and ethnicities could come together to form a new race of people; the American. It encompassed taking the good‚ strong qualities from each culture and keeping them to form an overall new culture. “Across four centuries‚ the steady arrival of millions

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
