this experiment equilibrium. Esterification is a slow and reversible reaction. The equation for the reaction between an acid RCOOH and an alcohol RẬᶦ can be the same or different; at equilibrium‚ the concentrations of both reactants and products are constant. In this experiment set up‚ the reaction between ethanoic acid and ethanol to produce ethyl ethanoate and water is a reversible reaction as shown by the following equation: CH₃COOH + CH₃CH₂OH↔CH₃COOCH₂CH₃ +H₂O The Equilibrium Law states that

atom of that element. The atomic number gives the “identity “ of an element as well as its location on the Periodic Table. No two different elements will have the atomic number. 4. The of an element is the average mass of an element ’s naturally occurring atoms‚ or isotopes‚ taking into account the of each isotope. 5. The of an element is the total number of protons and neutrons in the of the atom. 6. The mass number is used to calculate the number of

8% in 1950. This high rate of return kept for couples of years (1951-1955)‚ ranging from 29% to 31%. Starting from 1956‚ rate of return on invested capital in sulphur industry dropped sharply‚ all the way back to the profitability level of early 40’s 15% rate of return in only 2 years. This fall did not stop until the rate of return dropped to as low as 7.5% in 1963 where the very bottom was. From 1964‚ the profitability started to rise again. The rate of return went back to the original 15% level

Term Paper Le Corbusier ARTH220 D001 Spr 13 Dr. Irene Nero July 21‚ 2013 I first decided to write about Alberti‚ but then seeing that we were allowed to write about any architect we’ve come across in this course‚ I thought to myself who would be better than Le Corbusier or Frank Lloyd Wright; cliché’ ‚ but yet they’re the fathers of the modern Architecture. Alberti’s type of Architecture wasn’t in use and he’s only looked at as history. Modern Architecture is what we live in‚ what

In Victor Hugo’s novel Les Miserable’s‚ one character plays a part in each of the other character’s lives. Cosette‚ a little girl‚ is created to develop the rest of the “miserables” throughout the book. Fantine‚ Cosette’s mother‚ digs herself into the shameless lifestyle of prostitution and poverty‚ while trying to support Cosette. The Thenardiers become her home while her mother leaves in search for work. There‚ Cosette is used to clean and work. Through Cosette‚ the Thenardier’s are shown as they

CHEMICAL WASTE MANAGEMENT IN DEVELOPING COUNTRIES INTRODUCTION Chemical waste is managed in various ways‚ some which are environment friendly and some which are hazardous. It has effects on water supply‚ fertility of the soil‚ climate‚ health of individuals‚ et.c. What really matters is how well this waste is managed. Chemical waste management typically includes the collection‚ transportation‚ processing and recycling/disposal of chemical waste. In past times‚ it was the role of the country to

DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

Partner’s Name: Shanygne Swann Lab Report #2 Title of Experiment: Static Friction and Limiting Equilibrium Brief Theory of Experiment: In limiting equilibrium‚ the sum of the forces on block X and on the hanging masses (load) Y is zero. The load is increased to a value until block X just slides at constant speed when the table is tapped. Tapping the table destroys the limiting equilibrium condition momentarily by altering the balance between tension (T) in the string and the maximum force

was held in the recreation room in the basement of a church. There was an oblong table at the head of the two rows of chairs placed in a 360 degree circle. Participants: There were roughly 40-50 participants ranging in age from mid teens to late 50’s. There were only 5 females in attendance. This group’s ethnicity was about 85% Caucasian‚ 10% African American and 5% Latino.
