Rates of Reaction Coursework Aim: To find out how different concentrations of sodium thiosulphate (Na S2 O3) affects the speed of its reaction with Hydrochloric acid (HCL). Introduction When Sodium Thiosulphate and Hydrochloric acid react they produce a cloudy precipitate. Both of the chemicals are clear solutions and they react together to form a yellow precipitate of sulphur‚ the equation for this reaction is: Na2 S2 O3 + HCL‚ H2 O + NaCL + SO2 + S Sodium Thiosulphate + Hydrochloric

William son Eth er Synth esis Introduction In this reaction‚ an alcohol is deprotonated to form a good nucleophile‚ which then attacks the electrophile methyl iodide to form an ether. Tetrabutylammonium bromide‚ a phase transfer catalyst‚ is used to carry ions back and forth between the organic phase and the aqueous phase. OH O NaOH + NaI + H2O CH3I Before coming to lab‚ please review the following techniques: "Reluxing a reaction‚" "Extraction and washing‚" "Drying an Organic Solvent‚" "Evaporating

Assignment 4: Chapter 5 Case Study 1. Because CEOs are not just a top manager of companies‚ they also have functions like leaders and regulators. Their actions always affect the whole company culture. If they did what is wrong‚ their employees may think “if the leaders do it‚ then it’s not a wrong thing‚ and maybe I can do it as well”. CEOs should pay attention to the technology part‚ especially in the areas of security and ethics. To avoid the security problems‚ such as stolen proprietary information

Rebecca Crockett Shannon Lerro Argumentative Synthesis November 4‚ 2010 Does talking on the phone while driving affect the driver? Drivers shouldn’t be able to use phones while driving because it can be extremely hazardous for not only them but their passengers‚ or others traveling along the same road. If changing a radio station is considered a major distraction to drivers‚ how is it not a distraction to look down to find your cell phone? Cell phones‚ have been known to cause wrecks that can

Experiment 3: Stoichiometry of a Precipitation Reaction Abstract: In this experiment‚ the objective is to use Stoichiometry to predict the amount of product produced in a precipitation reaction. We received working knowledge of how to accurately measure reactants and products of the reaction. We then are able to use the data that we recorded to make assessments of the actual yield opposed to the theoretical yield. When we calculated the percent yield we are able

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

These regulators effect the activity of the phosphorylase but not the actual reaction. Regulators bind allosteric sites in order to effect the enzyme activity usually through conformation changes. The activity can either be increased or decreased depending on whether the regulator is an effector or inhibitor for the enzyme. An important
