CHM2330 Experiment F- Raoult ’s Law Experiment By: Sanah Assaad Student Number: 5267864 Partner: Jihad Arafa T.A: Didier University of Ottawa March 25‚ 2010 Objective: The purpose of this experiment is to study the total vapour pressure of ideal or non-ideal mixtures of two volatile liquids as a function of chemical composition. Introduction: For ideal mixtures of volatile liquids the vapour pressure of any given mixture may be obtained by applying Raoult ’s Law to each of

This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant. ------------------------------------------------- ------------------------------------------------- Introduction In a reaction where a slightly soluble ionic solid

is by eating chocolates. To confirm this assumption‚ the experimenter‚ Victor Seo has developed an experiment to prove the hypothesis: “people who consume lots of chocolate will produce more acne than people eat less chocolate. 400 students of teenagers with grades ranging from 9 to 11 will be examined divided into four groups each consuming 1 bar‚ 3 bars‚ 6 bars‚ or 10 bars daily. This experiment will remain over a time period of a month. Meals will be served in equal amounts and the amounts of

In 2003‚ Phillip McGraw‚ better known as Dr. Phil‚ created a weight loss solution that consists of seven steps that make up a process of learning and working on resolving the emotional and physiological obstacles to weight loss. In preparation to his program‚ Dr. Phil spent eight years counseling people who were up to three hundred pounds overweight. The first step in his solution is right thinking‚ which involves the individual taking responsibility for their weight problem. The second step is healing

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes. Bandura wanted to show‚ by using aggressive and non-aggressive adult-actors‚ that a child would be apt to replicate and learn from the behavior of a trusted adult (Shuttleworth‚ M. 2008). These issues have been present for many years‚ even before the media used these

Dr. Babasaheb Ambedkar- A Social Reformer. Abstract As per Dr. B.R. Ambedkar‚ the concept of socialism is based on the principles of justice‚ liberty‚ equality and fraternity. It is his thought that socialism can be achieved by State control over land‚ industries‚ religions‚ caste and through an elaborate scheme of constitutional method. As per him‚ caste consciousness hampers economic progress‚ so he suggested that the State should redistribute the land to poor farmers and it was his demand

The three characters that are going to be compared in this analysis are going to be: Eliza Doolittle‚ Henry Higgins‚ and Colonel Pickering. They stay with each other throughout the play‚ so it is mighty easy to see how they act towards each other. Higgins and Pickering decided to take Liza in and show her how to be a duchess. They not only teach her how to act like one‚ but they also teach her how to talk like one. Liza is a lower class flower girl‚ who goes around selling flowers to people to get

Introduction The major component of eggshells is calcium carbonate (CaCO3). Calcium carbonate cannot be dissolved in water‚ but can dissolve in an acid using the reaction: 2HCl(aq)+CaCO3(s) Ca2+(aq)+CO2(g)+H2O+2HCl-(aq) This reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Instead adding an excess of acid to dissolve all of the CaCO3 and then titrating the remaining H3O+ with NaOH solution can achieve the determination of the amount
