ractice Problem #1: Oxygen gas can be produced by decomposing potassium chlorate using the reaction below. If 138.6 g of KClO3 is heated and decomposes completely‚ what mass of oxygen gas is produced? KClO3 (s) --> KCl (s) + O2 (g) [unbalanced] Answer to Practice Problem #1: 1. Balance your equation first. 2KClO3 (s) --> 2KCl (s) + 3O2 (g) [balanced] 2. Convert from grams to moles using molar mass.

autobiographical story. On May 14‚1894‚ a five-day charity bazaar called Araby opened in Dublin. The name alludes to Arabia where open-air shops and rows of peddler carts lined the streets in an exciting cacophony. For children living in Dublin‚ Arabia enjoyed a mythical‚ mysterious aura. It was a far away place rich with exotic treasures‚ much different from damp and dreary Dublin. Joyce was twelve when the bazaar came to Dublin. The setting for the tale "Araby‚" the house on "North Richmond Street‚" was

Reaction Mechanisms The mechanism of a chemical reaction is the sequence of events that take place as reactant molecules are converted into products. Introduction The study of kinetics includes very complex and sophisticated reactions that cannot be analyzed without a proposed mechanism‚ a series of steps that a reaction takes before reaching the final products. Reaction mechanisms are step-by-step descriptions of what occurs on a molecular level in chemical reactions. Each step of the reaction

Gas law Experiment Anna CunananProfessor Stewart Chemistry 400 T/TH 1:30 PM 18 March‚ 2014 Objectives: In this Experiment‚ we will be decomposing KClO3 into two different compounds‚ KCl and O2. We are given a known mixture that has MnO2 in it to act as a catalyst. When decomposing KClO3 it releases O2 gas‚ which we then collect into the Erlenmeyer flask. The gas then displaces the water into the beaker‚ which we can then calculate the water evolved. The first method we use to determine the percent

This was done by measuring the changes in volumes of gas surrounding the organisms with a Volumeter. For the experiment with the pea seedlings‚ the rate of O2 consumption (measured in the presence of CO2 capturing Ascarite) was determined to be 2.6ml over the course of 30 minutes. Using the weight lost by the pea seedlings (assuming all weight loss was due to the metabolism of glucose)‚ and the equation for

Ireland has always been a mysterious land‚ and it was no different for the Vikings who attempted to conquer this puzzling land of Ireland. The politically fractured island appeared to be an easy target‚ but its apparent weakness turned out to be its greatest strength. The Viking era in Ireland is commonly divided into two periods. The first period beginning in 795 Ad and ending by the mid ninth century‚ the second period ranged from around 914 Ad and ending in the middle of the tenth century.

image of her lover’s eyes when he had told her that he did not wish to live.» James Joyce (Dublin‚ February 1882 – Zurich‚ Jenuary 1941) is an Irish writer who has depicted Dublin in his collection of short stories “Dubliners” (London‚ 1914)‚ and who has revolutioned narrative style and techinques with his mature work “Ulysses” (Paris‚ 1922). Even though Joyce spends most of his life abroad‚ leaving Dublin in his early twenties‚ he mantains a strong bond with his city‚ where he set his stories
