Introduction: Isotopes are explained as the variations of the number of neutrons that an element may have. Some isotopes are more common than others. This experiment was performed to help visualize the different isotopes of an element and show how some isotopes will appear more often than others.
The purpose of this experiment was to identify given Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield. Weighed 1 gram of NaC2H3O2 and mixed it with ionized water. Boiled 12 mL of 1.0M Acetic Acid added into a beaker containing the sodium carbonate on a hot plate until all the liquid is evaporated
Symbolism is a notable feature in Catching Fire. Through symbolism , Suzanne Collins manages to paint Katniss as the ultimate embodiment of rebellion through transferring her into a mockingjay . " A mockingjay is a creature the Capitol never intended to exist"(92), as it is a result of the Capitol's usage of the japperjays which were sent to spy on the rebels. However, the japperjays failed in their mission so the Capitol left them to die ,but they managed to survive through mating to female mockingbirds . This proves that the existence of the mockingjays is an act of rebellion in itself , an act of defiance excuted by the Capitol's own invention , long before Katniss has been born. . While in the Capitol , Katniss realizes that her
The book “Forged by Fire” by Sharon M. Draper is a book with many themes and lessons we all can learn. One of the themes that this essay will talk about will be about loyalty. For one thing, loyalty is a strong feeling because it’s something that comes from inside of a person to have faith in someone . We are all loyal to someone, someone who’s special in our lives and plays a major role in our lives that drags us to support them no matter what. In this book, Gerald gets abused by his drunk father. He wants to get rid of him, but Monique, the mother is very loyal to Jordan and defends him. This makes Gerald’s life miserable, and the only thing that brings a smile to his face is his step-sister, Angel, whom he possesses and cares for. Therefore, referring to some parts, and experience as a person, I can state that loyalty doesn’t always go both ways.
Prompt: “Write about a song you like and why?” My whole life revolves around music; everyday I’m going to either choir or orchestra. While I’m driving I’m singing along with the radio. Narrowing down all of the songs in my repertoire is a difficult task. After thinking about this question for a good half an hour I came to a conclusion. Liking a song doesn’t mean it has to be on the radio or on the track list of a pop star’s album; which is why a song I like is “Fiddles on Fire” by Mark Williams. This song is an iconic orchestra piece for Middle school or slightly advanced Elementary school orchestras. Its melody will infect your brain to the point of insanity. Ask any orchestra conductor their thoughts on “Fiddles on Fire”, and their face will immediately scrunch up in agony.
During the Progressive Era (1890’s - 1920’s) there were political reforms and social activism in the United States of America. These acts of social activism and political reformation were to fix issues in urban areas, fix issues in the garment industry, and to make a changes so tragedies (like the Triangle Fire) don’t happen again. The triangle fire serves as a microcosm for the progressive era because they both needed reformation but action was not taken until things became extreme.
The Great Chicago Fire was an significant event that took place in Chicago, Illinois in 1871. The fire burned more than $200 million dollars worth of property was destroyed along with the death of 300 people, and more than 100,000 people were left homeless.
After reviewing the topics in this course I found In the Watch & Think assignment "Death by Fire," Todd Willingham is arrested, tried and convicted of the murders of his three daughters and sentenced to death. Reports from the neighbors in the documentary claimed Willingham was "a very mean man" and by the law enforcement investigator Jimmie Hensley (2010),"You got to count his actions before and after. You got to count his actions during the fire, and things like that that makes the whole story. Not just one little segment of it, its every bit of the story.”
In a tragic event accruing in the early 1900s, resulting in the deaths of 145 factory workers, ultimately led to the development of several laws and regulations that would better shape labor condition throughout the United States. In the paperback “The Triangle Fire” written by Jo Ann E. Argersinger, there are numerous primary sources with personal stories reflecting how this heartrending event shaped survivors of the Triangle Fire. Life in the Shop, All for One, and The Roosevelt I Knew are three primary sources within the text that reveal the labor conditions before and after the fire, perspectives of workers themselves, factory
In April 2013, Matthew Yglesias, an American Economics Journalist proposed the people of Bangladesh would not appreciate having stronger safety standards in their country because it would cause undue harm economically. He asserts Bangladesh should have different lower standards for safety because they are a poorer country. Most of the people involved in the New York tragedy of 1911 also known as the Triangle Fire, would not agree with Matthew Yglesias on his assertion that lower economic status would be an indication of lower safety standards in factories. Namely, the workers, the union leaders, the progressive reformers and the political leaders would all vote for higher standards commiserate with the United States. The only ones who would not argue with Yglesias are the owners of the Triangle Factory with their vested interest, their own problems of multiple fires and accusations of safety neglect. They would agree with Yglesias. This is evidenced by the documents in The Triangle Fire by Jo Ann E. Argersinger.
The first modern flamethrower, Flammenwerfer, was invented by German engineer Richard Friedler in 1901. These powerful weapons used pressurized air, carbon dioxide or nitrogen to push oil through a nozzle, which was ignited by a charge, producing a jet of flame. Flame throwers were mainly used to clear enemy soldiers from the trenches. Richard Friedler developed two types of flamethrowers – the smaller version Kleinflammenwerfer was a portable one carried by one person, and the larger version Grossflammenwerfer was suitable for transportation, also by a single person. From 1911 onwards, the German army deployed flamethrowers in three specialized battalions. They used it first against French trenches at Malancourt, north of Verdun on 26 February 1915. The Germans made a surprise attack with the flamethrowers on the British troops at Hooge in Flanders on 30 July 1915. The French also used their portable one-man flamethrower, Schilt, a superior build to the
To determine the amount of iron in the iron tablets I carried out a titration, however the titration I carried out in a school lab is different to how titrations are carried out in industry. For example in schools, titrations are carried out by hand using a burette and measurements
This lab report discusses an experiment to study the difference in the burn rate of various colored candles. The objective of this experiment is to analyse the outcome of burning 5 different colored candles including white under the same control variable for 60 minutes. The white candles used in this experiment are pure and no chemicals or dyes are added to it. They are normally made from paraffin wax with a wick in the middle. Candles can also be made from soy wax, other plant wax or animal fat. Wax acts as a fuel to keep the candle burning. The wick has to be an absorbent twine with strong capillary ability. All candles used in this experiment are of the same height, size, shape and brand.
