Unknown 6- Isopropyl Alcohol We found that unknown 6 was Isopropyl alcohol. Its chemical name is isopropanol and the chemical formula C₃H₈O but is typically called isopropyl alcohol. Isopropyl alcohol is today used as a primary ingredient in rubbing alcohol. Is smells very unpleasant and is used for disinfecting pads used by medical professionals for tasks such as sanitizing small instruments, wiping down surfaces, and cleaning a patient’s skin before an injection. Since it is also a solvent, it has many cleaning uses. We predicted at once that is could be isopropanol because of its smell. Question: “What is the identity of unknown 6 in test tube 20?” Hypothesis: If I test the characteristic properties of unknown 6 then I will see its properties to be the same or similar to isopropanol. Characteristic property- Test 1- distillation Materials: Goggles, 250 ml beaker, 10 ml graduated …show more content…
Characteristic Property- Test 2- Density Materials: Triple Beam balance, distilled water, graduated cylinder, unknown 6 Procedure: first we found the mass of the empty graduated cylinder and then its mass with the now distilled unknown. After subtracting the mass of the graduated cylinder, we were able to find the volume. For every 1mL=1cm³ so there we had the volume found with the graduated cylinder. We divided the mass by the volume in order to get the density Data: We found that the density of our unknown was 0.76 g/cm3. Characteristic Property- Test 3- Flame Test Materials: tongs, unknown 6, matches Procedure: at the sink, we held a small piece of towel that was soaked with the liquid fraction 6 and held it with the tongs for the lit match to light it on fire. Data: We found that the unknown is flammable after it automatically lit on fire and burned during the burn test.

To find the density of the three coins, I followed a short and simple procedure. First, I used the triple beam balance to find the mass of each coin to the nearest tenth of a gram. Next, I filled the graduated cylinder with 50 mL of water. Then I put the quarter in the graduated cylinder. In my data table, I recorded the volume of the quarter and the the water in the graduated cylinder.
1. If given the power, I would support and convert the US system into a direct democracy which means the winner of the presidential popular vote would win the presidency. On page 182 in the book, it states that a direct democracy enables all actors with a voice (the ability to vote) to make decisions on the matter at hand. Furthermore, a direct democracy provides voice to those affected by the issue.
Our society would not be what it is today if it wasn't for the three French philosophers for the individual freedom, freedom in government, religion, economy, and gender equality. John Locke, Voltaire, and Adam Smith were four of the many great philosophers, who changed our society and the shaped the capitalistic democratic world that we live in today. These philosophers lived in a time of bright and amazing new ideas, known as the Age of Enlightenment or the Age of Reason. Here are the main ideas of Enlightenment. John Locke (1632-1704) was one of the three main French philosophers.
Enlightenment The enlightenment was a time in which leaders and philosophers promoted ideas during the seventeenth and eighteenth centuries that influenced people's thoughts concerning politics, social justice, human progress and religion forever. As said by Philosopher Immanuel Kant, “Enlightenment is defined as the upset of the established order/the awakening of one’s mind/forsaking society’s imposed mindset and establishing one for yourself.” (Document 12) These scientists like Issac Newton and writers like John Locke were challenging the old ways and because of that people became socially aware.
Over the last few class periods, our Theory of Coaching Soccer class viewed the documentary Class of 92. This film focuses on and showcases six young soccer-playing men who would go on together as members of the Manchester United to conquer the world in the arena of soccer. The Class of 92 follows (as a reenactment) the journey of these six young men (Paul Scholes, Ryan Giggs, David Beckham, Nicky Butt, and Gary and Phil Neville).o This film begins with a nostalgic scene of the soccer players intently listening in on a game they played in on May 26, 1999. After the opening scene, the film sets the stage for following each player and their individual journey as a part of the team and a part of the Manchester United.
Unbroken is a biography by Laura Hillenbrand about Louie Zamperini’s entire life. Louie Zamperini is a son of Italian Immigrants that moved to Torrance, California. He starts out as a problem child that would steal, drink and smoke, but he eventually straightens out through sports and became an Olympian later in life. After he went to the Olympics, he gets drafted into World War 2.
The Horrors of the Naoetsu POW Camp Throughout Laura Hillenbrand’s Book Unbroken: An Olympian’s Journey from Airman to Castaway to Captive, Louie is sent to numerous POW camps but eventually ends up at the Naoetsu POW Camp, where he is finally liberated. This camp, the last that Louie has to endure, does not come without struggles and beatings that can put anyone over the edge. Although all parts of the Naoetsu POW camp were horrible, the worst parts were the dreadful living conditions, a wretched prison guard, and extensive torture sessions that caused men to lose all hope of survival. Living conditions at the Naoetsu POW Camp were deplorable and unsanitary, causing Louie’s mental health to decline and his life to worsen. On page 201 of Unbroken,
In the time of the Enlightenment Period many changes were happening in society. In the late 17th and 18th century people called The Philosophers, met in French salons and English drawing rooms to discuss what they believed in. They made many great things happen and strived their best to make what they believed in something possible. The Enlightenment Philosophers imagined they could change the ways of society in many ways. They concluded that they could improve the laws, rights of women, religious rights, and also economic rights.

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.
The Title IX is a law that requires all education programs, mainly sports, that are federally funded to have gender equality. In 1906 the NCAA (National Collegiate Athletic Association) was created for formatting and enforcing rules in men's football, but it soon became the ruling body for college athletics. The NCAA was great for men but not so much for women, women did not get athletic scholarships and there were no championships for women's teams. In 1972 the Title IX was signed by President Nixon and passed, allowing more women to join sports teams and get college degrees. Currently there are more than 2.6 million girl athletes in high school and more than 150,000 in college.
Unit 2 discussion Assignment Using one of the referenced website articles discuss how OS creates the illusion of virtualization by virtualizing the CPU. By running one process, then stopping it and running another, and so forth, the OS can promote the illusion that many virtual CPUs exist when in fact there is only one physical CPU (or a few). last week we learn and discussed about one of basic and fundamental concepts and what about of the operating system and in generally how it 's working and it 's own component that related to complete the work as a group like a team. from this perspective, I would use one of the reference website articles that given for this week and introduced to the concepts of operating systems and discuss one of the most fundamental abstraction that the operating system provides to us to use .
A. Plan of Investigation This investigation will analyze the role of Unit 731, a Japanese biological and chemical warfare research and development unit, during the Japanese occupation in Manchuria. This investigation will be focused on both direct and indirect actions and experiments conducted by the unit that officially goes by the name of ‘Epidemic Prevention and Water Purification Department of the Kwantung Army’. Collection of essays, official articles and testimonies will be mostly used to evaluate the depth of the unit’s role in Manchuria. The two main sources for this investigation: Japan’s Wartime Medical Atrocities: Comparative Inquiries in Science, History and Ethics edited by Jing Bao Nie, Nanyan Guo, Mark Selden and Arthur Kleinman, and Unit 731: Testimony by Hal Gold will be analyzed for their origins, purposes, values and limitations.

The 11+ an IQ test used to determine the type of school a child would attend was highly influenced by psychologist Sir Cyril Burt, Burts research appeared to show that intelligence was largely inherited and could be measured. It was right to assume that a child should then go to a school that suited their intelligence and abilities, although in the results of the 11+ there was a strong suggestion that class had a major influence on the results of the test with middle-class children getting higher scores therefore many more middle-class children gaining entry to the grammar schools. Burts research was later discredited because much if his research had been invented. Although research still showed there was a connection between measured intelligence and achievement in education (Haralambos, M., Holborn, M. 2000). Arthur Jensen (1973) an American psychologist defines intelligence as "abstract reasoning ability" and argues that it is simply a small
