Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely

Critical Lens Essay Fyodor Dostoevsky’s quote “Fear is simply the consequence of every lie” shows that when one is not honest to someone and comes out of it. I agree with Dostoevsky’s quote. Ultimately lying causes worrying and fearing that the person that was lied to will find out the truth. This statement is clearly explained in “The Necklace” by Guy de Maupassant and “The Tell Tale Heart” by Edgar Allen Poe. In “The Necklace” Madame Loisel lost a necklace of her friends and bought another

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

The Iodine Clock Investigation Introduction This is an investigation into the rate of a reaction and the factors that contribute to how fast a reaction will take place. Through the recording and analysis of raw data‚ this investigation also allows us to apply generally accepted scientific rules and to test them against results gained from accurate experimental procedures. Aim The aim of this experiment is to investigate the rate at which iodine is formed when the concentration

character in this film is the reason behind his success and what drives him to win. Willy is introduced as a person who is motivated by the bolstering of his resume; someone who cares deeply about what his achievements say about him and seeks wins simply for the accolades that accompany it. This can be seen in his win percentage itself. When DA Joe Lobruto (David Strathairn) points out that Willy traded all of his losing cases‚ Willy

When Walden was published during the nineteenth century‚ the reactions of people were exceedingly different than they are of modern society. These reactions were towards every aspect of Thoreau and altered with every change in time. The foremost reactions toward Henry David Thoreau occurred when he went to live on his own at Walden Pond. As strange as it may seem‚ some critics think that Thoreau’s choice to live at Walden Pond was simply because he was a hermit. However‚ his sheltered life was the
