Lab 4: Le Chatelier’s Principle Name: Cammey Mahowald Lab Partners: None Date of Experiment: March 16‚ 2015 Course: CHE 112 Abstract: The purpose of this experiment is to understand the components of a reaction at chemical equilibrium and use Le Chatelier’s principle to predict the direction an equilibrium position will shift upon changes in the concentration‚ temperature‚ and pressure. It was determined that in the equilibrium of chromate and dichromate it is an exothermic reaction and in the

Step 1: Read the Grandfield College scenario on p. 18 of the textbook. (COMPLETED) Step 2: Identify the major topics for this database. Track the software that faculty and staff use on their computers. Find out what software does the school own. Find out what versions of software does the school own. Find out what is the license agreement for the software versions that Grandfield College owns. Make sure that out of the several different licensing schemas that Grandfield College uses the least restrictive

Objective: During this lab‚ you will investigate the relationship between the angle of an applied force and the magnitude of one component. You will compare your actual force with the theoretical force and provide a computer generated data table that calculates the theoretical values. You will graph your actual and theoretical values and provide a complete table of % errors for your results. Your paragraph will discuss all the questions below in depth. Procedure and Data: 1. Tie the two pieces of

Objectives: • To be able to explain how the photoelectric effect experiment works and why a photon model of light is necessary to explain the results. • To study the effect of intensity of light on photoelectric experiment. • To estimate the Planck’s constant‚ h through the simulation. • To be determine how to calculate the wavelength of light‚ the work function of the metal‚ or the stopping potential‚ if given the other two. Beginning with the plate made of sodium. Keep all the parameters

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) The eyewash fountain is used to rinse chemical splashes off the eyes. They are used by rinsing the eyes 15 to 30 minutes with water. b. Fire Blanket (2 points) Fire blankets are used to extinguish small fires. They are used by covering the small fires with the blankets until it extinguishes. c. Shower (2 points) Safety showers were made to eliminate any

The purpose of this experiment is to conduct different experiments that will illustrate the different gas laws. We will be given a list of equipment need to perform the experiment as well as general rules to help us do the experiment. We will investigate three properties of gases pressure‚ temperature‚ and volume. By doing this experiment we will be able to define the gas laws. According to Boyles‚ it states that a fixed amount of ideal gas that is kept at a fixed temperature‚ that the pressure and

1. What is the goal or objective of an IT risk assessment? The aim of the risk assessment process is to remove a hazard or reduce the level of its risk by adding precautions or control measures‚ as necessary. By doing so‚ you have created a safer and healthier workplace. 2. Why is it difficult to conduct a qualitative risk assessment for an IT infrastructure? It is difficult to conduct a qualitative risk assessment for an IT infrastructure because it determines the level of risk based on the probability
