Chemical Equilibrium Lab Report Aim: The aim of the lab “Chemical Equilibrium” is to observe the effects of changes in concentrations of products and reactants on the position of the equilibrium of given chemical reactions. Background Information: We are going to use our knowledge of the Le Chatelier’s principle in order to observe this experiment. The principle states that the equilibrium will shift in the direction that will minimize the effects of the change. This lab consists of two parts

Preparation of an Ester Acetylsalicylic Acid (Aspirin) OBJECTIVE: To become familiar with the techniques and principle of esterification. DISCUSSION: Aspirin is a drug widely used as an antipyretic agent (to reduce fever)‚ as an analgesic agent (to reduce pain)‚ and/or as an anti-inflammatory agent (to reduce redness‚ heat or swelling in tissues). Chemically‚ aspirin is an ester. Esters are the products of reaction of acids with alcohols‚ as shown in the following equation using

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab Report 3: Daphnia‚ Human and Crayfish Cardiac Activity Introduction An electrocardiogram‚ abbreviated as ECG in this report‚ is a visual representation of an organism’s atrial and ventricular depolarization and repolarization. Previous research has shown that although there is variability in the amplitude and shape of the waves of ECG‚ dependent on the subject’s health‚ it follows a universal pattern that can be used effectively for biometrics. The experiments discussed in this lab report were

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew

Dylan McFarland 9/15/14 Honors Chemistry Richardson Lab: Measuring the Density of Pennies Pre-Lab Questions: 1. The equation that relates density‚ mass‚ and volume is: density = mass / volume. 2. All substances have unique densities‚ so if you are able to find the density of a substance‚ you can properly identify it. 3. We measure irregular-shaped objects with the use of water displacement because it would be nearly impossible to get the exact measurements

Lab Report for Chemical Changes and Conservation of Mass Lab Previous to the reaction‚ the magnesium appeared to be a solid‚ white‚ black‚ and grey substance with many small dark particles within the substance. The hydrochloric acid was a clear liquid that looked like water It weighed 42.2 grams in total. During the reaction‚ the two substances produced bubbles‚ creating smoke and became warm with a smell that is irritating to the human nose. After the reaction‚ it appeared to be a clear‚ bubbly

Light Microscopy Lab Lab write-up 1 Parveen Rajper Biology 101 Principles of Biology 1 September 29‚ 2012 Introduction: The light microscope helps see the microscopic world that the naked eye cannot see. If there were no microscopes in the world‚ than it would be very difficult to understand the many particles that surround the living world. The purpose of this lab experiment is to become familiar with a microscope. It is hypothesized that it will be difficult

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and
