Philippines ABSTRACT This experiment was performed to learn the technique of acid-base titration and to compare the efficiency of commercially available antacids by looking at their weight of HCl and weight of antacid values. The analysis of antacid tablets was highlighted in this experiment. The efficiency of antacid tablets was determined and compared when the number of grams of HCl can be neutralized by 1 gram of the tablet was found. First‚ the two antacid tablets (Kremil-S) were crushed and weighed

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Experiments: Doctors‚ Experiments‚ and Results Melissa Anjeanette Edwards POLYTECH High School of Kent County‚ Woodside‚ Delaware Abstract During World War II experiments were done on the prisoners of war in Nazi Germany. Doctors for these camps came in all shapes and sizes including former S.S. Troops‚ Women‚ and a variety of prisoner doctors. The experiments differed as much as the doctors themselves; however they stayed the same in one factor‚ medical curiosity become killing in atrocious

Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

risk with either currency futures or currency options. It is generally suggested that hedgers should choose a hedge instrument that matches the risk profile of the underlying currency position as closely as possible. This advice‚ however‚ ignores the possibility that the hedging effectiveness may differ for the alternate risk management tools. This study compares the effectiveness of currency futures and currency options as hedging instruments for covered and uncovered currency positions. Based on

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

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

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

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
