Properties of Gases CHE101 Experiment date: 06/20 Write-up date: 06/21-06/22 Purpose: The purpose of this experiment is to examine different properties of gases in order to be able to identify them in a laboratory setting. I will be using Hydrochloric acid‚ mossy zinc‚ Bromothymol blue‚ limewater‚ Manganese‚ and Alka Seltzer‚ to test different properties of gases formed by chemical reactions. In order to extract the gas I will use several household products such as vinegar‚ baking soda‚ water

ab: Observing a Chemical Reaction Name: Deja Eason Period: 5th Period Partners: Melingh Patterson‚ Tori Millens Date Performed: 9/2/11 Teacher: Mrs. Medina Abstract: This experiment was all about observing a chemical reaction. During the experiment‚ we made observations and possible explanations on why Copper(II)Chloride Dehydrate and Aluminum foil created a chemical reaction. The observations were made by using Copper Chloride‚ Aluminum foil‚ and Distilled water. Before the Aluminum

In this paper‚ I will give the Department of Defense (DoD) definition of accountability and responsibility while explaining the importance of maintaining positive physical security of a Common Access Card (CAC) which is a piece of the “intelligence puzzle” and vital to Operational Security (OPSEC). The paper will give examples of how the lack of positive security of a CAC can‚ not only‚ diminish a soldier’s ability to perform daily tasks‚ but also limit their access to information pertinent to the

Chemical equilibrium is a state of balance within a system of chemical reactions. Equilibrium in chemistry is achieved when substances are produced and broken down at the same rate and thus‚ the number of molecules of each substances becomes constant. Thermodynamics is a branch of physical science that involves the relationship between heat and other forms of energy (Energy‚ Enthalpy‚ and the First Law of Thermodynamics). There is a more specific area of thermodynamics that explicitly pertains to

Chemical and Physical Changes in Matter Purpose: The purpose is to observe chemical and physical changes and to identify each. Procedure: Do experiments 1-8 as directed by the handout. Data and Results: Experiment | Observations | Type of Change | Supporting Evidence | 1 | -After a few seconds‚ yellow smoke was produced-Wood splinters are becoming black-Bottom part of test tube has black color on the sides-Some woods splinters have been burned to ash-Middle of test tube has yellow

Introduction: The purpose of this lab was to differentiate chemical changes from physical changes. During the separation lab we were given a test tube with Styrofoam‚ sand‚ salt‚ and Iron fillings in it‚ our goal was to issolate each component from the other. We were given certain tools and materials to help us figure out how to divide the components‚ therefore creating our lab. Doing this lab helped us figure out what component used physical change and which used chemical change‚ it also showed us which

Michael Sherman Unit 6 Lab The first step for risk management would be identifying all of your assets. These assets can include the servers you use to sell your electronic parts‚ as well as all of your data‚ from customer information to the data to build the parts you sell. It also includes any networking devices and end user workstations. Evaluate what the cost to your company would be if these assets went down. How would the current confidentiality‚ integrity‚ or availability be affected
