  • 9-Fluorenone Lab Report

    The objective of this experiment was to oxidize 9-fluorenol with bleach to form 9-fluorenone. This was done with three different reactions, each under different conditions. The reactions were evaluated using the TLC plate to see how far each reaction progressed. During the experiment reaction test tube 2 had the darkest yellow color out of the three reactions. On the TLC plate the starting material had one dot, with an Rf value of 0.22. Reaction 1 had two dots, with Rf values of 0.29 and…

  • Ketones By Reducing 4-T-Butylcyclohexanone

    The purpose of this lab was to perform reduction of ketones by reducing 4-t-butylcyclohexanone with sodium borohydride (NaBH4) to form 4-t-butylcyclohexanol. At the end of this experiment, the infrared spectroscopy was obtain for the final product, 4-t-butylcyclohexanol. The IR graph showed the presence of the desired product, and it also showed if the reaction went to completion or not. In addition, the mass of the final product was obtained to determine the percent yield. To a 5mL conical…

  • The Kinetic Molecular Theory: Why Gases Behave The Way They Do

    The Kinetic Molecular Theory explains why gases behave the way they do. It explains how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container,…

  • Glacial Acetic Acid Lab Report

    The procedure of the experiment includes two parts: 1. Determination of the Freezing Point of Glacial Acetic Acid: to record the temperature of acetic acid every 30 seconds until it reach 300 seconds (5 minutes). 2. Determination of the Molar Mass of an Unknown Compound: to record the temperature of the mixture between unknown solid and glacial acetic acid. After that, put the ice-water mixture into the tube and record the temperature every 30 seconds. Pre lab questions: 1. Solute: dissolved…

  • Essay On Trebuchet

    Trebuchet: A machine used in medieval siege warfare for hurling large stones or other missiles. This is one of the most important and game changing weapon of all time. When the trebuchet is fired, the weight box falls and the force of gravity causes rotational acceleration of the attached throwing arm around the axle (the fulcrum of the lever). The throwing arm is usually four to six times the length of the counterweight portion. These factors multiply the acceleration transmitted to the…

  • Canadian Involvement In Ww1

    Canadian Involvement: The Canadian Parliament didn't choose to go to war in 1914. The country's foreign affairs were guided in London. So when Britain's ultimatum to Germany to withdraw its army from Belgium expired on 4 August 1914, the British Empire, including Canada, was at war, allied with Serbia, Russia, and France against the German and Austro-Hungarian empires. The first major battle fought by Canadian troops in the First World War took place from 22 April to 25 May 1915, outside the…

  • American Biological Warfare In 1763

    During World War I, The United States developed the Chemical Warfare Service, and briefly conducted research on a lethal, natural, plant protein called ricin, but after the signing of the Geneva Protocol, which prohibited "asphyxiating, poisonous or other gases, and of all analogous liquids, materials or devices" and "bacteriological methods of warfare," all research on chemical weapons were officially terminated. However, as The United States’ involvement in conflict…

  • Gravimetric Analysis Of Calcium Carbonate

    Gravimetric Analysis of a Metal Carbonate Purpose The purpose of this lab is to find the mass of an unknown metal by conducting a double-displacement precipitation reaction, which is our gravimetric analysis. Once we find the precipitate mass, we can then find the molar mass by using the molar ratio given in the reaction equation. Procedure First, we set up the ring stand with a Bunsen burner, put a crucible on top of the pipe stem triangle and heated the crucible for a minute, then let it…

  • Limonene Research Paper

    Introduction: Limonene is a terpene that can be isolated from orange peels almost 100% in the (R)-(+)-limonene form. The essential oil from the orange peel belongs to terpenes, which are compounds that are made up of two or more five carbon units, named isoprene.1 The limonene is a monoterpene, which means it is made up of two isoprene units. Natural products are related compounds formally derived from isoprene units are terpenoids.3 The skeleton of terpenoids may differ from strict additivity…

  • Why Droplets Grow Lab Report

    There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle. Once the aerosol particles are large enough, they become cloud droplets that will have a different mechanism of growing. Cloud droplets grow differently because they are larger in size. Instead, they grow by a new process…
