Chemical Equilibrium: Le Chatelier Principle By Sarah Ramos and Kristina Todorovic Chemistry 203 DEN Dr. Mohamed El-Maazawi Part A. Acid-Base Indicators Purpose In this part of the experiment‚ we will find a reagent that will shift the acid-base equilibrium reaction described by Equation (2) in one direction and then a second reagent that will cause the equilibrium position to shift back in the opposite direction. Introduction An acid–base indicator

he terms “chemical accident” or “chemical incident” refer to an event resulting in the release of a substance or substances hazardous to human health and/or the environment in the short or long term. Such events include fires‚ explosions‚ leakages or releases of toxic or hazardous materials that can cause people illness‚ injury‚ disability or death. While chemical accidents may occur whenever toxic materials are stored‚ transported or used‚ the most severe accidents are industrial accidents‚ involving

Diamond Chemicals PLC Executive Summary Diamond Chemicals is considering two mutually exclusive projects‚ the Merseyside project and the Rotterdam project‚ for the production of polypropylene When considering the Merseyside project‚ senior-management wants a positive impact on earnings per share. The addition to earnings per share was £28‚800 with an average addition of £2‚000 per year2. Calculated with erosion‚ the addition to earnings per share was £18‚800 with an average addition of £1

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test

In the first reaction‚ magnesium was burned to produce magnesium oxide. The reaction produced a bright light‚ which is evidence of a chemical change. The second reaction occurred as a result of solid magnesium reacting with hydrochloric acid. The reaction produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to

Chemical Nomenclature refers to the naming systems used with chemical formulas. This worksheet focuses on the most basic chemicals and nomenclature systems. Please read the information concerning each problem set and then attempt the problems associated with that information. The simplest compounds contain just two elements. Sodium chloride‚ NaCl‚ is an example of a binary compound. Several other examples are listed below. Potassium bromide KBr Calcium bromide CaBr2 Lithium fluoride LiF

to include some potential solutions. First‚ it is agreed that the price for depreciation to the transport division’s equipment should not be included in the proposal. The transport division is responsible for overseeing movement of all raw‚ intermediate‚ and finished materials throughout the company and if the depreciation cost is included in the analysis it would artificially inflate profit for that division. The Transport Division and Intermediate Chemicals Group also have its own vice presidents

CHEMICAL EQUILIBRIUM Reversible reactions and dynamic equilibrium Ammonia (NH3) is an important industrial chemical that is used in the manufacture of fertilisers. It is manufactured by reacting hydrogen with nitrogen. The reaction is said to be reversible and the conversion of reactants to products is never complete. N2 + 3H2 2NH3 A reversible reaction is a reaction which can take place in either direction When the concentrations of the reactants and product have become constant‚ a
