Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine those ratios. During this reaction‚ hypochlorite ions oxidize the thiosulfate

Columbus‚ the man who discovered the new world‚ infact did not discover it‚ for it was inhabited by migrants from Asia‚ more than fifteen thousand years ago‚ almost one thousand years before Columbus landed in America. Christopher Columbus was‚ despite the arguments a Genoan man and infact Christian‚ and he had two brothers and a sister. He sailed a thirty-three day trip on his first voyage and ‘found’ America on October twelfth. But‚ before this‚ Columbus had to go through the queen in order to

Title: Stoichiometry of a Precipitation Reaction Purpose: The purpose is to predict the amount of precipitation using stoichiometry. Another purpose is to measure and calculate percentage yield. Procedure: 1. Weigh out 1.0g of CaCl2*2H2O and put it into a 100mL beaker. 2. Add 25mL of distilled water and stir. 3. Using stoichiometry to determine how much Na2CO3 is needed for a full reaction. 4. Weigh the calculated amount and put it in a small paper cup. Add 25mL distilled water and stir

Kaily Purtle 09-10-2012 Study of the Family Reaction Paper 1 In class we discussed Reading #4. This reading was about the “Super Mom”. We discussed our personally experiences along with readings. We talked about how stay at home mothers and working mothers get looked at by society and by their husbands. I will be writing my reaction paper on this topic because it is very interesting to me. The “Super Mom” is described in the White and Klein text as a “stroller in one hand‚ brief

This is one thing that the two lead characters in the movie do not contain over themselves. They both made sacrifices just to be able to have the title of the one who has the greatest magic trick. They sacrificed their friendship‚ their families‚ even their lives. Before they started their rivalry‚ they both have good relationship with each other‚ good family‚ a

Department of Chemistry Chem 180 Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances. Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water‚ the ions separate and become surrounded by water molecules. The focus of this experiment is on precipitates. The goal of this experiment is to study the nature of ionic reactions‚ write balanced equations‚ and to write

before being killed. I imagine it to be similar to my reaction of seeing a dead dog on the side of the freeway (some sadness if I stop to dwell on the thought)‚ compared to a seeing suffering dog just after being hit by the car (deep sadness to the extent of tears). The Concentration Camp sort of opened my eyes to my inner reactions towards death and my much deeper ractions towards suffering. The Holocaust reading further showed me my reactions to death. As they read countless names of small children

Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction rate with
