Chemical compounds that are available to determine are CaCO3, CaCl2, Ca(NO3)2, mgCl2, MgSO4, KCl, HCl, HC2H3O2, KNO3, K2SO4, NaC2H3O2, Na2CO3, NaCl, Na2SO4, HNO3, H2SO4, HNO3, H2SO4, NH4Cl, (NH4)2SO4, K2CO3, 0.1 M AgNO3, 0.2 M BaCl, Mg(s), NaOH, and KOH. To start this experiment, start with the flame test by gathering a Bunsen burner and a Nichrome wire. Connect the Bunsen burner with a rubber tube to a laboratory gas. To prepare solutions for the flame test, weigh out 0.205 gram of Unknown Compound using an analytical balance and mixed it into a 140 mL beaker filled with 20 mL ionized water. Ensure that solid is completely dissolved using a stirring rod.
Some compounds have very distinctive colors when burned, such as Potassium, which is a white/purple, and sodium, which is a deep red hue. The first step for a flame test is to gather the needed materials. These include beakers, distilled water, the unknown substance, a Bunsen burner, matches, a nichrome wire, tubing to connect the gas line to the Bunsen burner, goggles, and known compounds to compare with. The first step is to make aqueous solutions of all the substances to be tested. This is done by adding .5
'Flames and Dangling Wire ' just like 'Meatworks ' portrays Earth as a kind of hell, where humans have destroyed what good parts there are about nature. "There is fog over the hot sun" emphasises the waste of humans and humanity that wastes not only nature but themselves. The hot sun would make the dump smell terrible, but they are still inside the car at this point. "A water bird lifts above this swamp as a turtle moves on the Galapagos shores" is a strong simile; a direct comparison to a prominent issue. However, nature will prevail and go above humanity, even if humans treat the earth like an experiment or their playground.
Kylie Kenneavy April 7, 2024 U.S. History Since 1877. The Triangle Fire trial was a famous trial that took place in December of 1911 after a detrimental fire broke out in March of the same year. This fire took place at a shirtwaist factory in Manhattan, New York City. 146 workers’ lives were taken during the fire from smoke inhalation while trapped inside with limited ways out, and other fatalities occurred from employees jumping out of windows nine to ten floors high.
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. Right before the Progressive era, America was full of living condition issues, political leader problems, and issues among the people. A serious urban issue included “Laws regulating factories were worthless if not enforced, a truth horribly demonstrated a
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.
Doctor Irving Greenberg, a Modern Orthodox rabbi contemplates the question of whether it makes sense to believe in God after the Holocaust in his Cloud of Smoke, Pillar Fire” (1977). Considering the nature of the Holocaust as a historical transforming event and its substantial death toll, that is taking the lives of six million Jewish, several postulations surrounding the subject of God after the Holocaust have emerged, such as the works of Richard Rubenstein, Eliezer Berkovits, and Hans Jonas to name a few. Greenberg’s work explores that when considering the horrible nature of the Holocaust, it may be fallacious to believe in God and moreover disrespectful to its victims. However, despite of this, there are still moments in which God is present,
In Table 1, Trial 1 and Trial 2 contain two mol of oxygen reacting with four mol of hydrogen to obtain that 1:2 ratio. As seen in the observation of distance the rockets flew, the farthest distances were found to be when this ratio was used. Also, the rocket that flew the farthest in the entirety of Table 1 was found in Trial 2 when oxygen was added to the pipet first. This observation does coincide with the hypothesis which predicted the addition of oxygen to the system first would produce the greatest propulsion. The remaining trials typically followed a trend characterized by a decrease in distance flown with an increase in the number of moles of oxygen in the combustion reaction.
Feelings of Inadequacy and Low Self-Worth Feelings and emotions can manifest themselves in many ways. Some individuals bottle them up while others wear them on their sleeve. Guy, from Edwidge Danticat’s “A Wall of Fire Rising,” focuses on operating a hot air balloon to escape his feelings of inadequacy, even at the expense of his family. The author uses Guy’s feelings of inadequacy to show how poverty and social expectations can take a toll on a person’s idea self-worth. While others may interpret Guy’s motives differently in the end he is successful in avoiding his feelings but left a broken family behind.
A flamethrower is a device designed to project flames and massive clouds of smoke in a controlled manner during wars. It was mostly used in battlefields, fortifications, bunkers and any other closed or shielding location. It was used because it can jet out flames up to 20 yards away from where the person controlling it is standing. It was also created to be carried and used by a single soldier. The device was first used on February 26, 1915 by the German 3rd pioneer regiment.
Alicia Suskin Ostriker's, “The Window, at the Moment of Flame” and Jack Gilbert's Michiko Dead” are poems that connect to the reader to deliver different, yet powerful and complex themes. There are different thematic statements that really bring out the author's strong feelings behind what many may think the thematic concepts says. “The Window, at the Moment of Flame” was written two weeks after 9/11 showing a glimpse of what it means to be an innocent American in a world wracked by violence. Ostriker says she was trying to "mostly tap a sense of looking on helplessly at human madness"(Friday Pick). Her poem is written in the first person point-of-view and we see directly into a child’s mind in the first line, and as the distance increases
In this lab we studied the properties of hydrogen and oxygen gases in order to determine the best chemical ratio of H2:O2 for the explosive reaction between the two gases when forming H2O. To preform this lab, we tested different ratios of hydrogen and oxygen by taking Zinc and hydrochloric acid to form hydrogen and manganese and hydrogen peroxide to form oxygen. Once we made these two gases we collected them by putting a pipet full of water on top of the stopper. We tested different ratios like 1:1 H2:O2, 2:1 H2:O2, 1:2 H2:O2, 3:1 H2:O2, 1:3 H2:O2. When testing our ratios, we believed that the ratio 2:1 was the best ratio for explosive reaction between the two gases when form H2O because of the loud pop and flame reaction it produced.
3. The machines control the amount of the two liquids that enter the combustion chamber so that they
To Build a Fire During the story “To Build a Fire” the theme that is developed is that sometimes you have to trust animals instincts because they might know more about the fire than you do. The setting of the story is on the Yukon Trail and it is seventy five degrees below zero while the man and the dog are on the trail. The reason they are on the trail is because the man is trying to find the camp to get food, water, and shelter. There are two ways the theme is developed. One way that the theme is developed is that the man made a fire to keep him warm, but later the man wanted to continue on the trail to try and find the camp.
The results indicated that white candles burn the slowest and red candles burn the fastest. The processed data indicates that after completion of 60 minutes, the white candle reduced from a height of 1.4cm to 0.6cm, while the red candle was reduced to a height of 0 cm. Furthermore all the other colored candles were recorded at a lower height, compared to the white candle after burning for 60
