Reaction

Introduction Four reactions were done using coffee cup calorimetry for each. Two Styrofoam cups were stacked together for each reaction performed, with a piece of cardboard used as lid with a hole for the thermometer. The beginning and final temperatures were taken for all reactions and solvents used. The end result and point of the experiment is to find what ΔH. Also this is a constant pressure calorimetry experiment. The goal of each of the reactions is to get ΔHrxn which is represented in…

Initially, sand and hydrogen peroxide were added in a test tube to create a mixture. Based on the observation conducted, no reaction was visible (i.e. no gas occurred). In result, the solution did not react because it does not contain the desired enzyme in order to break down H2O2. An enzyme is needed to decompose H2O2 into water and oxygen. With this knowledge, students were able to determine that the results for the rest of the tests did make sense. For example, the solution contained…

This refres to a reaction in which there is not enough O2 in order to react with atom C in buthane to change into CO2 therefore they will change to carbon monoxide. The oxygen reacts with H to produce H2O these can be defined by incompelete combustion. Use Markovnikov's Rule to explain why Propan-2-ol is formed during the reaction between propene and steam. (A.C. 2.3) According to his role if a HX compound was added to an unsymmetrical alkene the H will bond to the compound. As propane is an…

The table below shows what colour the solution has turned after Amylase solution and Benedict’s solution has been added to Starch solution at different temperatures. The tests were completed three times each temperature to find an average. This graph resembles the results from the table above. Making it obvious to observe the unexpected results as the temperatures 2, 20 and 27 remained blue then 37 degrees changed to green and 60 degrees changed to orange. This experiment was carried out to…

Chemical reactions Sabatier’s reaction When hydrogen combines with carbon dioxide at around 350 Celsius in the presence of alumina, ruthenium or nickel catalyst, it gives methane and water. CO2 + 4 H2 → CH4 + H2O This reaction can be used to produce water in empyreal. CO2can be extracted from mars and the waste from the industrial torus where there is high levels of CO2 H2 can be obtained from electrolysis The methane can be used as a fuel in industries. GRAVITY Empyreal has a torus…

A. Bio-reactions I’ve experienced all of the bio-reactions at various times during my life. When I was 15 years old, I got into trouble with some friends. This was a time that I experienced the “freeze” bio-reaction and I stopped interacting with anyone. I have always experienced the “flight” reaction when I encounter clowns and will avoid being near one. Currently, I sometimes experience the “fight” reaction when I think about returning to school. A1. Bio-Reaction Experienced When I was…

As sentient beings we experience bio-reactions in one form or another on a daily basis. In the following I will discuss three specific situations I have experienced resulting in different bio-reactions including; fight, freeze, and appease. Situation 1: I was approximately 21 years old and at a BBQ with friends and their families. The children were all playing in the backyard with the parents standing around and talking, my 4 year old was riding his tricycle around the pool and fell in I felt…

peroxide was added. The flask was swirled until it was a homogenous mixture. Next, the reflux apparatus was set up. After set up was completed, the round bottom flask was heated in a heating mantle attached to a transformer that was set to 80%. The reaction was heated until the reflux began. The reflux was maintained for 30 mins without the condensation ring going above 1/3 of the…

How does one change when their best friend, the one person that they can rely on, suddenly becomes withdrawn, depressed, and that kid who skips school? One answer can be seen in Rachel’s reaction in Speak by Laurie Halse Anderson. In this book the main character is Melinda who is raped by Andy Evans at a party. Melinda called the police on the party, but won’t tell anyone why. As a result, everyone hates Melinda, which doesn’t help her recovery from post-traumatic stress disorder. In the end,…

Afghanistan: There were many challenges in the military but I am choosing to write about one scenario that made me realize what type of person I am. Even though I had struggle all through school, I was surprisingly good at being a Marine. Once I finished my first year in the military my parents grew to be pretty comfortable with the idea of me being in the corps. I think it is because they saw that I was finally growing up. In the Marine Corps they do not care about excuses and they definitely…
