In part one the Styrofoam cups and the substances that are in the cup which is distilled water and sodium hydroxide was the system while the stir rod and thermometer and the Vernier unit is the surroundings. In part two the Styrofoam calorimeter, HCl and NaOH are the system while the stir bar and the tool that is used to measure the temperature is the surroundings. In part 3 HCl, Styrofoam cup calorimeter and NaOH are the system while the temperature probe, stirring rod are the soundings 6.)…

The purpose of the experiment was to observe limiting reactants by using a fixed amount of one reagent along with a varying the amount of the second reagent used in a chemical reaction. Through these results, the concept of limiting reactants can be determined. Using a graph to demonstrate the relation between the volumes of hydrogen gas produced versus the moles of the reagents will help figure out the stoichiometric balance required. The success of the experiment will be determined by the…

and define the current understanding of human rights. The maturing and growth of human rights has helped to progress the widespread wellbeing of billions around the world. Overtime, historical publications have in this process, including the Cyrus Cylinder, the United Nations Declaration of Human Rights and the New Zealand Bill of Rights. With the increasing freedom, the examples of abuse and denial of rights have escalated. An example of this is the denial of gay rights. However, many…

According to the average density and the boiling point of the experiment, the probable identify liquid of M4C is Propanol (Isopropyl alcohol), with the density value is (0.788 g/mL) and boiling point is (82.67 *C) compare with the literature value of density (0.785 g/mL) and the boiling point (82.4 *C), which Propanol (Isopropyl alcohol) should be the liquid of M4C. The Propanol (Isopropyl alcohol) has no color. The key of identify the unknown is the boiling point and the density, because if…

previous experiments were stuck into the tube, which might possibility be blocking the carbon dioxide to reach to the measuring cylinder. This could be the main reason for the large scatter results. Therefore, the results for 2 and 2.5 grams yeast concentration can be concluded as invalid. Another random error is that the present of air bubbles in the measuring cylinder after inverted which resulted in inaccurate measuring of carbon dioxide released. Additionally the volume of water in the water…

2.3. Pharmacokinetics of (S)-ketoprofen 2.3.1. Blood sampling On the day of the study, rats were cannulated approximately 30 min before uric acid injection and 3 h before the drugs were administered. The animals were anesthetized and the caudal artery was cannulated with a PE-10 cannula (Clay Adams, Parsippany, NJ, USA) connected to a PE-50 cannula. The cannula was kept patent with heparinized saline solution and stopped with a needle. Rats were allowed to recover from anesthesia and…

design for a small two-cylinder car that Cadillac had rejected. Murphy bought into Brush’s idea, and decided it should carry the name “Oakland” as did his horse-drawn vehicles. During the summer of 1907, Murphy organized the Oakland Motor Car Co. His lack of sales with the Oakland, a two cylinder vertical engine that rotated counterclockwise, convinced him that Cadillac might have been right in rejecting the Brush design. In 1909, they introduced a line of 40 HP four-cylinder cars with sliding…

per-formance and emissions of a port-fuel injected SI engine fuelled with ABE and gasoline with volumetric ratios of 0%, 20%, and 40% to create various fuel blends. Moreover, pure gasoline was also used as a baseline for comparison of ABE fuels. In-cylinder pressure data revealed that the peak pressure of ABE20 was higher comparing to gasoline and ABE40 showed a lower peak pressure.…

Amazon Echo Print Ad In the online retail giant, Amazon ad in Popular Science, for the Amazon Echo. There is a large cylinder seen from a top down view. The ad has a dark blue background with a gradient that goes towards the cylinder in the center. The ad has large text above the cylinder that says just ask. While also having questions in a circular pattern around the cylinder. At the bottom of the ad there is small text that talks about how it can answer a questions hands free and the other…

There have been many people whose names, when referenced, are commonly accompanied by the phrase, “The Great”. Although it has been proven throughout history that many people are not shy of hyperbole, there is one historical figure whose greatness is not exaggerated. This man’s name was Cyrus the Great. As his title suggests, Cyrus the Great was highly regarded by his subjects, as well as people born years after his passing. “Father” to the Iranians, and “Liberator” to the Babylonians, Cyrus…
