Measurement of Mass‚ Volume‚ and Density through Archimedes Principle Overview: The purpose of this experiment was to measure the density of a solid and a liquid using Archimedes principle. Archimedes is one of the greatest inventors and mathematicians of all time. The principle we used in this experiment was discovered when Archimedes stepped into a full bath tub. Using Archimedes principle‚ we were able to determine the density of a lead rod‚ water‚ and an unknown liquid. Physical Data:

07.05 Le Chatelier ’s Principle Research Project Fritz Haber was born in December of 1868‚ in Prussia to a German chemical merchant. He went into the field of organic chemistry at the University of Jena. He was appointed as director of the Kaiser Wilhelm Institute for Physical Chemistry in Berlin in 1911. He was in charge of forming a center for cross-disciplinary research and gave his country the knowledge of ammonia and other significant fertilizers. He left Germany in 1933 after their loss

Lab: 5 Experiment:13 Pre-Lab The purpose of this experiment is to observe an equilibrium reaction counteracting changes to it’s system all in accordance to Le Chatelier’s principle. An equilibrium reaction can be pushed toward products or reactant based on changes in temperature or concentration. The reversibility of reaction will also be looked at. Pre-Lab questions 1. The concentrations of products and concentrations of reactants remain constant but both reactions

LE CHATELIER’S PRINCIPLE EXPERIMENT 2 AMANDA BUCHANAN – SEPTEMEBER 15‚ 2015 CHEMISTRY 1212- SECTION 50 OBJECTIVES: The objectives of this experiment are to be able to define equilibrium‚ equilibrium position‚ equilibrium constant‚ reaction quotient and Le Chatelier’s Principle. Another objective is to explain how changes in temperature‚ pressure and concentration affect the equilibrium position of a reaction. Also‚ perform chemical equilibrium reactions and manipulate equilibrium positions

Experiment 11 Date: 28-3-2011 Title: Interpretation of reaction by the Le Chatelier’s principle Objective: To determine the factors that affecting the equilibrium position Introduction: Le Chatelier’s principle states that if a system in equilibrium is subjected to a change‚ the equilibrium position of the system will shift in a direction to minimize the effect of the change. Iron(III) ions and thiocyanate ions (NCS-) react in solution to produce thiocyanatoiron(III) (FeNCS2+)‚ a

Experiment No. 2: Dynamic Equilibrium and Le Chatelier’s Principle December 1‚ 2011 Final Formal Results Le Chatelier’s Principle states that “when a stress is applied to a chemical system at equilibrium‚ the equilibrium shifts in a direction that reduces the effect of stress” (Gross‚ Abenojar‚ and Tan 23). Moreover‚ it helps us “predict the direction of the shift of the equilibrium” (Silberberg 745). Silberberg also stated that there are three kinds of disturbances - concentration‚

Preparation of SKEO The extraction of S. khuzistanica was performed by hydro distillation and clevenger apparatus for 5 hours. Once extraction was completed‚ the resulted essential oil was dehydrated using sodium sulfate (Merck). The essential oil was stored at temperature of 4ºC until using (12). In order to provide different concentrations of the extract‚ Dimethyl sulfoxide (DMSO) was used. Gas chromatography/mass spectrometry analysis of essential oil Isolation and measurement of the sample
