In this lab‚ theoretical chemical equations of ionic compounds were balanced by the group to determine ratios of reactants and products. The products were determined by the group through switching the cation with their anion partner. Using this information‚ it was determined by the group‚ whether the reaction should result in a solid‚ gas‚ or water based on theoretical solubility. Then several experiments testing the reaction of these ionic compounds were performed by the partners. Two ionic compounds

How do the unique chemical and physical properties of water make life on earth possible? Heat Capacity the amount of energy required to raise the temperature of something one degree celcius Cohesive strength - The internal strength of the adhesive. The measure of a label’s resistance to removal. Surface Tension - the attraction of molecules to each other on a liquid’s surface‚ creating a barrier between the air and the liquid.

Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants

Lab #4: The Immune System Purpose: The purpose of this lab was to perform and understand the procedures of conducting an ELISA test to determine whether a particular antibody is present in a patient’s blood sample through a virtual simulation. Hypothesis: If I successfully complete this lab‚ I will then understand how to perform an ELISA test‚ the purpose an ELISA test‚ and also how to interpret the results of this test. Materials and Procedures: Materials: Howard Huges medical

Introduction The following report shows that the proposal of the modernisation project should obtain funding from the corporate headquarters of Victoria Chemicals. The project has an initial outlay of GBP12 million to renovate and rationalise the polypropylene production line at Merseyside plant. This is done in order to make up for deferred maintenance and exploit opportunities to achieve increased efficiency. This report will look at the following four main areas of concern in order

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

Overview: This paper presents statistics on major factors that affects the property crime rates in the U.S. Abstract: The property crime rates of 45.7% occurs more in urban areas. About 16.8% of the crimes were committed by high school dropouts and only 0.4% of the crimes that occurs were related to the population density. The type of property crimes that happens includes larceny-theft‚ home burglary‚ home invasion‚ grand theft auto‚ forgery‚ and arson. These types of crimes may be caused by factors

Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that
